Siemens SIMATIC S7 series PLC Used in various industrial fields, including energy, water conservancy, oil, natural gas, chemical, building automation, and manufacturing. S7-1200 During firmware update to V2.0.3 It is possible to set the controller to Stop/Detect Status, causing communication errors (for example, by running a network scan to send malformed HTTP flow). Therefore, communication errors occur at S7-1200 Web Server interface that allows the controller to enter Stop/Detect status. In automation applications, Stop/Detect A state is a state defined when an external process is stopped.

The Neighbor Discovery (ND) protocol implementation in Cisco IOS on unspecified switches allows remote attackers to bypass the Router Advertisement Guarding functionality via a fragmented IPv6 packet in which the Router Advertisement (RA) message is contained in the second fragment, as demonstrated by (1) a packet in which the first fragment contains a long Destination Options extension header or (2) a packet in which the first fragment contains an ICMPv6 Echo Request message. IOS is prone to a security bypass vulnerability. Cisco IOS is an operating system developed by Cisco in the United States for its network equipment

Veri-NAC is a network control access device. The input passed to the WEB interface via the URL lacks filtering before use, and the attacker submits a request containing a directory traversal sequence to obtain arbitrary file content. In addition, its Active Directory authentication information is stored in clear text. Veri-NAC is prone to a directory-traversal vulnerability. Exploiting the issues can allow an attacker to obtain sensitive information that could aid in further attacks. Veri-NAC firmware version prior to 8.0.10 are vulnerable. ---------------------------------------------------------------------- Join Secunia @ FIRST Conference, 12-17 June, Hilton Vienna, Austria See to the presentation "The Dynamics and Threats of End-Point Software Portfolios" by Secunia's Research Analyst Director, Stefan Frei.

Golden FTP Server is a Windows platform FTP server. A stack buffer overflow vulnerability exists in the GoldenFTP PASS command because of a security vulnerability in the Golden FTP service that allows a malicious user to trigger a buffer overflow using the PASS command. This vulnerability can be exploited by remote attackers to cause sensitive information to leak.

Buffer overflow in RSEds.dll in RSHWare.exe in the EDS Hardware Installation Tool 1.0.5.1 and earlier in Rockwell Automation RSLinx Classic before 2.58 allows user-assisted remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a malformed .eds file. RSLinx Classic connects RSLogix and RSNetWorx products to Rockwell Automation networks and devices, and is also an OPC server. Execute arbitrary code. RSLinx Classic is prone to a remote buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied input. Failed exploit attempts will likely cause denial-of-service conditions. RSLinx Classic 1.0.5.1 is vulnerable; other versions may also be affected

The MODACOM URoad-5000 is a portable WiMAX/WiFi router. The MODACOM URoad-5000 device uses the modified RaLink SDK version to access standard web interfaces via HTTP. The WEB management interface can be accessed by admin:admin via a standard username/password, which can be changed later. But there is another engineer:engineer pair can also be changed by the WEB interface. MODACOM URoad-5000 is prone to a security-bypass vulnerability and a remote command-execution vulnerability. An attacker can exploit these issues to bypass certain security restrictions and execute arbitrary commands on the affected device. MODACOM URoad-5000 firmware version 1450 is vulnerable; other versions may also be affected

expat_erl.c in ejabberd before 2.1.7 and 3.x before 3.0.0-alpha-3, and exmpp before 0.9.7, does not properly detect recursion during entity expansion, which allows remote attackers to cause a denial of service (memory and CPU consumption) via a crafted XML document containing a large number of nested entity references, a similar issue to CVE-2003-1564. Ejabberd is an instant messaging server for the Jabber/XMPP protocol. There is an error in processing part of the XML input. ---------------------------------------------------------------------- Alerts when vulnerabilities pose a threat to your infrastructure The enhanced reporting module of the Secunia Vulnerability Intelligence Manager (VIM) enables you to combine advisory and ticket information, and generate policy compliance statistics.

Cisco Media Processing Software before 1.2 on Media Experience Engine (MXE) 5600 devices has a default root password, which makes it easier for context-dependent attackers to obtain access via (1) the local console, (2) an SSH session, or (3) a TELNET session, aka Bug ID CSCto77737. The Cisco MXE 5600 includes a root account for advanced debugging, but is not required for normal operations. The root account is different from the admin and user accounts. If Telnet is enabled, it can also be accessed via Telnet. An attacker can exploit this issue to gain unauthorized administrative access to the affected device. Successful exploits will result in the complete compromise of the affected device. This issue is being tracked by Cisco bug ID CSCto77737. A software upgrade is not required to resolve this vulnerability. Customers can change the root account password by issuing a configuration command on affected engines. The workarounds detailed in this document provide instructions for changing the root account password. To determine the software release that is running on a Cisco MXE unit, log in to the device and issue the show version command-line interface (CLI) command to display the system banner. The following example shows a Cisco MXE 5600 device running software version 1.2.0-34. No other Cisco products are currently known to be affected by this vulnerability. For instructions on how to set or change the root password, see the Workarounds section of this advisory. Vulnerability Scoring Details ============================= Cisco has provided scores for the vulnerabilities in this advisory based on the Common Vulnerability Scoring System (CVSS). The CVSS scoring in this Security Advisory is done in accordance with CVSS version 2.0.

The NetGear WNDAP350 is a wireless access device. The NetGear WNDAP350 wireless access point lacks the correct restrictions on access. An attacker can exploit the vulnerability to obtain sensitive information, including plain text management passwords or WPA ciphertext, through the download.php or BackupConfig.php script. WNDAP350 with firmware 2.0.1 and 2.0.9 are vulnerable; other firmware versions may also be affected

The helper application in Cisco AnyConnect Secure Mobility Client (formerly AnyConnect VPN Client) before 2.5.3041, and 3.0.x before 3.0.629, on Linux and Mac OS X downloads a client executable file (vpndownloader.exe) without verifying its authenticity, which allows remote attackers to execute arbitrary code via the url property to a Java applet, aka Bug ID CSCsy05934. The Cisco AnyConnect SSL VPN ActiveX and Java clients contain a vulnerability that can allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system. Cisco AnyConnect Secure Mobility Client is a remote access solution from Cisco that is Cisco's next-generation VPN client. WEB pages that use social engineering spoofing or other vulnerabilities to entice users to access, allowing an attacker to provide arbitrary executable programs for the helper application to download and execute. This issue is tracked by Cisco Bug IDs CSCsy00904 and CSCsy05934. There are no workarounds for the vulnerabilities described in this advisory. This advisory is posted at: http://www.cisco.com/warp/public/707/cisco-sa-20110601-ac.shtml Affected Products ================= Vulnerable Products +------------------ The vulnerabilities described in this document apply to the Cisco AnyConnect Secure Mobility Client. The affected versions are included in the following table: +------------------------------------------------------------+ | Vulnerability | Platform | Affected Versions | |-------------------+-----------+----------------------------| | | Microsoft | All versions prior to | | | Windows | 2.3.185 | | |-----------+----------------------------| | Arbitrary Program | | * All versions in major | | Execution | | releases other than | | Vulnerability | Linux, | 2.5.x and 3.0.x. | | | Apple | * 2.5.x releases prior | | | MacOS X | to 2.5.3041 | | | | * 3.0.x releases prior | | | | to 3.0.629 | |-------------------+-----------+----------------------------| | | Microsoft | All versions prior to | | Local Privilege | Windows | 2.3.254 | |Escalation |-----------+----------------------------| | Vulnerability | Linux, | | | | Apple | Not affected | | | MacOS X | | +------------------------------------------------------------+ Note: Microsoft Windows Mobile versions are affected by the Arbitrary Program Execution Vulnerability. No other Cisco products are currently known to be affected by these vulnerabilities. After the user logs in, the browser displays a portal window and when the user clicks the "Start AnyConnect" link, the process of downloading the Cisco AnyConnect Secure Mobility Client begins. The helper application is a Java applet on the Linux and MacOS X platforms, and either a Java applet on the Windows platform or an ActiveX control if the browser is capable of utilizing ActiveX controls. The downloaded helper application is executed in the context of the originating site in the user's web browser. This arbitrary executable would be executed with the same operating system privileges under which the web browser was run. Common Vulnerabilities and Exposures (CVE) IDs CVE-2011-2039 (for CSCsy00904) and CVE-2011-2040 (for CSCsy05934) have been assigned for these vulnerabilities. An attacker may engineer a web page to supply an affected version of the ActiveX control or Java applet and still accomplish arbitrary program execution because of the lack of authenticity validation. When this occurs, an old version of the ActiveX control will not be instantiated if one is presented for download. This action accomplishes the same result as the previous recommendation -- it deploys new, fixed versions of the ActiveX control so that old, vulnerable versions of the control are not instantiated if one is presented for download. This action prevents the ActiveX control from being instantiated under any scenario. Instructions for setting the kill bit are beyond the scope of this document; refer to the Microsoft Support article "How to stop an ActiveX control from running in Internet Explorer" at http://support.microsoft.com/kb/240797 and the Microsoft Security Vulnerability Research & Defense's "Kill-Bit FAQ" blog posts referenced in the Microsoft Support article for more information. Note that this CLSID did not change with new versions of the ActiveX control that implement code signing validation. Mitigating the risk of old versions of the Java applet can be accomplished by blacklisting old, vulnerable versions using the Jar blacklist feature introduced with Java SE 6 Update 14. For information on the Jar blacklist feature refer to the Java SE 6 Update 14 release notes, available at: http://www.oracle.com/technetwork/java/javase/6u14-137039.html The jar files to be blacklisted are identified by the following SHA-1 message digests: # 2.3.0254, 2.3.1003, 2.3.2016, 2.4.0202, 2.4.1012, # 2.5.0217, 2.5.1025, 2.5.2001, 2.5.2006, 2.5.2010, # 2.5.2011, 2.5.2014, 2.5.2017, 2.5.2018, 2.5.2019 SHA1-Digest-Manifest : xmarT5s8kwnKRLxnCOoLUnxnveE= # 2.2.0133, 2.2.0136, 2.2.0140 SHA1-Digest-Manifest : 2wXAWNws4uNdCioU1eoCOS4+J3o= # 2.0.0343, 2.1.0148 SHA1-Digest-Manifest : OlNnvozFCxbJZbRfGiLckOE8uFQ= Local Privilege Escalation Vulnerability +--------------------------------------- Unprivileged users can elevate their privileges to those of the LocalSystem account by enabling the Start Before Logon (SBL) feature and interacting with the Cisco AnyConnect Secure Mobility Client graphical user interface in the Windows logon screen. To prevent this issue, fixed versions of the Cisco AnyConnect Secure Mobility Client limit the amount of interaction that is possible in the client's graphical user interface when it is displayed on the Windows logon screen.

Successful exploits will result in the complete compromise of affected computers. Versions prior to AnyConnect Secure Mobility Client 2.3.254 are vulnerable. There are no workarounds for the vulnerabilities described in this advisory. The affected versions are included in the following table: +------------------------------------------------------------+ | Vulnerability | Platform | Affected Versions | |-------------------+-----------+----------------------------| | | Microsoft | All versions prior to | | | Windows | 2.3.185 | | |-----------+----------------------------| | Arbitrary Program | | * All versions in major | | Execution | | releases other than | | Vulnerability | Linux, | 2.5.x and 3.0.x. | | | Apple | * 2.5.x releases prior | | | MacOS X | to 2.5.3041 | | | | * 3.0.x releases prior | | | | to 3.0.629 | |-------------------+-----------+----------------------------| | | Microsoft | All versions prior to | | Local Privilege | Windows | 2.3.254 | |Escalation |-----------+----------------------------| | Vulnerability | Linux, | | | | Apple | Not affected | | | MacOS X | | +------------------------------------------------------------+ Note: Microsoft Windows Mobile versions are affected by the Arbitrary Program Execution Vulnerability. No other Cisco products are currently known to be affected by these vulnerabilities. This action causes the browser to first download a "helper" application that aids in downloading and executing the actual Cisco AnyConnect Secure Mobility Client. The helper application is a Java applet on the Linux and MacOS X platforms, and either a Java applet on the Windows platform or an ActiveX control if the browser is capable of utilizing ActiveX controls. The downloaded helper application is executed in the context of the originating site in the user's web browser. An attacker could create a malicious web page that looks like the normal VPN web login page and entice a user, through social engineering or exploitation of other vulnerabilities, to visit it. This would allow the attacker to supply an arbitrary executable that the helper application would download and execute on the machine of the affected user. This arbitrary executable would be executed with the same operating system privileges under which the web browser was run. Common Vulnerabilities and Exposures (CVE) IDs CVE-2011-2039 (for CSCsy00904) and CVE-2011-2040 (for CSCsy05934) have been assigned for these vulnerabilities. Additional Considerations for the Arbitrary Program Execution Vulnerability +------------------------------------------------------------ Note that while new versions of the ActiveX control and Java applet that are shipped with the Cisco AnyConnect Secure Mobility Client make use of code signing to validate the authenticity of components downloaded from the VPN headend, there is still the issue of old versions that do not validate downloaded components. An attacker may engineer a web page to supply an affected version of the ActiveX control or Java applet and still accomplish arbitrary program execution because of the lack of authenticity validation. Mitigating the risk of old versions of the ActiveX control can be accomplished in the following ways: * Load fixed Cisco AnyConnect Secure Mobility Client versions on the VPN headend and establish a VPN connection (via web browser or standalone client). This action will cause the new version of the Cisco AnyConnect Secure Mobility Client, including a new version of the ActiveX control to install. When this occurs, an old version of the ActiveX control will not be instantiated if one is presented for download. This action accomplishes the same result as the previous recommendation -- it deploys new, fixed versions of the ActiveX control so that old, vulnerable versions of the control are not instantiated if one is presented for download. This action prevents the ActiveX control from being instantiated under any scenario. Instructions for setting the kill bit are beyond the scope of this document; refer to the Microsoft Support article "How to stop an ActiveX control from running in Internet Explorer" at http://support.microsoft.com/kb/240797 and the Microsoft Security Vulnerability Research & Defense's "Kill-Bit FAQ" blog posts referenced in the Microsoft Support article for more information. Note that this CLSID did not change with new versions of the ActiveX control that implement code signing validation. Mitigating the risk of old versions of the Java applet can be accomplished by blacklisting old, vulnerable versions using the Jar blacklist feature introduced with Java SE 6 Update 14.

The helper application in Cisco AnyConnect Secure Mobility Client (formerly AnyConnect VPN Client) before 2.3.185 on Windows, and on Windows Mobile, downloads a client executable file (vpndownloader.exe) without verifying its authenticity, which allows remote attackers to execute arbitrary code via the url property to a certain ActiveX control in vpnweb.ocx, aka Bug ID CSCsy00904. The Cisco AnyConnect SSL VPN ActiveX and Java clients contain a vulnerability that can allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system. Cisco AnyConnect Secure Mobility Client is a remote access solution from Cisco that is Cisco's next-generation VPN client. When the Cisco AnyConnect Secure Mobility Client is deployed from the VPN front end, a WEB browser is used to initialize an SSL connection to the VPN front end. After the user logs in, the browser displays the portal window. When the user clicks \"Start AnyConnect\", the process will start downloading the Cisco AnyConnect Secure Mobility Client. The helper application is a Java Applet on Linux and MacOS X platforms or a Java Applet on a Windows platform or an ActiveX plugin on a browser. The downloaded Helper program is in a web browser. The initial site context is executed. The helper program then downloads the program from the VPN front end and executes it. An attacker can exploit this issue by using social engineering techniques to coerce unsuspecting users to download and execute arbitrary applications. This issue is tracked by Cisco Bug IDs CSCsy00904 and CSCsy05934. The control itself is provided by the server upon connecting. For more information, visit the following URL. http://www.cisco.com/en/US/docs/security/vpn_client/anyconnect/anyconnect23/release/notes/anyconnect23rn.html II. The vulnerability exists within the ActiveX control with the following identifiers: CLSID: 55963676-2F5E-4BAF-AC28-CF26AA587566 ProgId: Cisco.AnyConnect.VPNWeb.1 File: %WINDIR%\system32\vpnweb.ocx This ActiveX control is not marked as safe for initialization or scripting within the registry, but it does implement IObjectSafety. When queried, this control's IObjectSafety interface reports that it is safe for both scripting and initialization. Once it is instantiated, it will attempt to download two files from the site supported in the "url" property. As such, an attacker can craft a page such that the control will download an executable of their choosing. One of the files will be executed upon the successful completion of the download. III. An attacker typically accomplishes this via social engineering or injecting content into compromised, trusted sites. Additionally, in a default configuration, a targeted user must have this control already installed or must accept several warning prompts at the time that the attack is taking place. This control is not on the white list included with Internet Explorer 7.0. More information can be found at the following URL. http://msdn.microsoft.com/en-us/library/bb250471.aspx IV. V. WORKAROUND Setting the kill-bit for this control will prevent it from being loaded within Internet Explorer. However, doing so will prevent legitimate use of the control. VI. For more information, consult their advisory at the following URL. http://www.cisco.com/en/US/products/products_security_advisory09186a0080b80123.shtml VII. This is a candidate for inclusion in the CVE list (http://cve.mitre.org/), which standardizes names for security problems. VIII.

This advisory is posted at: http://www.cisco.com/warp/public/707/cisco-sa-20110601-ac.shtml Affected Products ================= Vulnerable Products +------------------ The vulnerabilities described in this document apply to the Cisco AnyConnect Secure Mobility Client. The affected versions are included in the following table: +------------------------------------------------------------+ | Vulnerability | Platform | Affected Versions | |-------------------+-----------+----------------------------| | | Microsoft | All versions prior to | | | Windows | 2.3.185 | | |-----------+----------------------------| | Arbitrary Program | | * All versions in major | | Execution | | releases other than | | Vulnerability | Linux, | 2.5.x and 3.0.x. | | | Apple | * 2.5.x releases prior | | | MacOS X | to 2.5.3041 | | | | * 3.0.x releases prior | | | | to 3.0.629 | |-------------------+-----------+----------------------------| | | Microsoft | All versions prior to | | Local Privilege | Windows | 2.3.254 | |Escalation |-----------+----------------------------| | Vulnerability | Linux, | | | | Apple | Not affected | | | MacOS X | | +------------------------------------------------------------+ Note: Microsoft Windows Mobile versions are affected by the Arbitrary Program Execution Vulnerability. No other Cisco products are currently known to be affected by these vulnerabilities. An attacker could create a malicious web page that looks like the normal VPN web login page and entice a user, through social engineering or exploitation of other vulnerabilities, to visit it. This arbitrary executable would be executed with the same operating system privileges under which the web browser was run. Common Vulnerabilities and Exposures (CVE) IDs CVE-2011-2039 (for CSCsy00904) and CVE-2011-2040 (for CSCsy05934) have been assigned for these vulnerabilities. An attacker may engineer a web page to supply an affected version of the ActiveX control or Java applet and still accomplish arbitrary program execution because of the lack of authenticity validation. When this occurs, an old version of the ActiveX control will not be instantiated if one is presented for download. This action accomplishes the same result as the previous recommendation -- it deploys new, fixed versions of the ActiveX control so that old, vulnerable versions of the control are not instantiated if one is presented for download. This action prevents the ActiveX control from being instantiated under any scenario. Instructions for setting the kill bit are beyond the scope of this document; refer to the Microsoft Support article "How to stop an ActiveX control from running in Internet Explorer" at http://support.microsoft.com/kb/240797 and the Microsoft Security Vulnerability Research & Defense's "Kill-Bit FAQ" blog posts referenced in the Microsoft Support article for more information. Note that this CLSID did not change with new versions of the ActiveX control that implement code signing validation. Mitigating the risk of old versions of the Java applet can be accomplished by blacklisting old, vulnerable versions using the Jar blacklist feature introduced with Java SE 6 Update 14. For information on the Jar blacklist feature refer to the Java SE 6 Update 14 release notes, available at: http://www.oracle.com/technetwork/java/javase/6u14-137039.html The jar files to be blacklisted are identified by the following SHA-1 message digests: # 2.3.0254, 2.3.1003, 2.3.2016, 2.4.0202, 2.4.1012, # 2.5.0217, 2.5.1025, 2.5.2001, 2.5.2006, 2.5.2010, # 2.5.2011, 2.5.2014, 2.5.2017, 2.5.2018, 2.5.2019 SHA1-Digest-Manifest : xmarT5s8kwnKRLxnCOoLUnxnveE= # 2.2.0133, 2.2.0136, 2.2.0140 SHA1-Digest-Manifest : 2wXAWNws4uNdCioU1eoCOS4+J3o= # 2.0.0343, 2.1.0148 SHA1-Digest-Manifest : OlNnvozFCxbJZbRfGiLckOE8uFQ= Local Privilege Escalation Vulnerability +--------------------------------------- Unprivileged users can elevate their privileges to those of the LocalSystem account by enabling the Start Before Logon (SBL) feature and interacting with the Cisco AnyConnect Secure Mobility Client graphical user interface in the Windows logon screen. To prevent this issue, fixed versions of the Cisco AnyConnect Secure Mobility Client limit the amount of interaction that is possible in the client's graphical user interface when it is displayed on the Windows logon screen. Vulnerability Scoring Details +---------------------------- Cisco has provided scores for the vulnerabilities in this advisory based on the Common Vulnerability Scoring System (CVSS). The CVSS scoring in this Security Advisory is done in accordance with CVSS version 2.0. CVSS is a standards-based scoring method that conveys vulnerability severity and helps determine urgency and priority of response. Cisco has provided a base and temporal score. Customers can then compute environmental scores to assist in determining the impact of the vulnerability in individual networks. Cisco has provided an FAQ to answer additional questions regarding CVSS at: http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html Cisco has also provided a CVSS calculator to help compute the environmental impact for individual networks at: http://intellishield.cisco.com/security/alertmanager/cvss * CSCsy00904 & CSCsy05934 - Arbitrary Program Execution Vulnerability CVSS Base Score - 7.6 Access Vector - Network Access Complexity - High Authentication - None Confidentiality Impact - Complete Integrity Impact - Complete Availability Impact - Complete CVSS Temporal Score - 6.3 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed * CSCta40556 -- AnyConnect: Security issue with SBL on versions prior to 2.3 CVSS Base Score - 7.2 Access Vector - Local Access Complexity - Low Authentication - None Confidentiality Impact - Complete Integrity Impact - Complete Availability Impact - Complete CVSS Temporal Score - 6.0 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed Impact ====== Arbitrary Program Execution Vulnerability +---------------------------------------- Exploitation of this vulnerability may allow an attacker to execute arbitrary programs on the computer of a Cisco AnyConnect Secure Mobility Client user with the privileges of the user who is establishing the VPN connection.
