Stack-based buffer overflow in ataudio.dll in the Cisco WebEx WRF Player 26.x before 26.49.32 for Windows, 27.x before 27.10.x (aka T27SP10) for Windows, 26.x before 26.49.35 for Mac OS X and Linux, and 27.x before 27.11.8 for Mac OS X and Linux allows remote attackers to cause a denial of service (application crash) or execute arbitrary code via a crafted WebEx Recording Format (WRF) file. Cisco WebEx is prone to multiple remote buffer-overflow vulnerabilities because the software fails to perform adequate boundary checks on user-supplied data. An attacker can exploit these issues to execute arbitrary code with administrative privileges. Successful exploits will completely compromise affected computers. Failed exploit attempts will result in a denial-of-service condition. ---------------------------------------------------------------------- Do you have VARM strategy implemented?

The Cisco WebEx WRF Player is an application that is used to play back WebEx meeting recordings that have been recorded on the computer of an on-line meeting attendee. The WRF Player can be automatically installed when the user accesses a WRF file that is hosted on a WebEx server. The WRF Player can also be manually installed for offline playback after downloading the application from www.webex.com. If the WRF Player was automatically installed, the WebEx WRF Player will be automatically upgraded to the latest, non-vulnerable version when users access a WRF file hosted on a WebEx server. If the WebEx WRF Player was manually installed, users will need to manually install a new version of the player after downloading the latest version from www.webex.com. Cisco has released free software updates that address these vulnerabilities. This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20091216-webex.shtml. Affected Products ================= Vulnerable Products - ------------------- The vulnerabilities disclosed in this advisory affect the Cisco WebEx WRF Player. Affected versions of the WRF Player are those prior to the "first fixed" versions, which are shown in the section "Software Versions and Fixes" of this advisory. To check if a Cisco WebEx server is running an affected version of the WebEx client build, users can log in to their Cisco WebEx server and go to the Support -> Downloads section. The version of the WebEx client build will be displayed on the right-hand side of the page under "About Support Center", for example "Client build: 27.11.0.3328". There is no way to check if a manually installed version of the WRF Player is affected by these vulnerabilities. Therefore, Cisco recommends that users upgrade to the most current version of the player that is available from http://www.webex.com/downloadplayer.html. Products Confirmed Not Vulnerable - --------------------------------- The Cisco WebEx Player for the WebEx Advanced Recording Format (ARF) file format is not affected by these vulnerabilities. No other Cisco products are currently known to be affected by these vulnerabilities. Details ======= The WebEx meeting service is a hosted multimedia conferencing solution that is managed by and maintained by Cisco WebEx. The WebEx Recording Format (WRF) is a file format that is used to store WebEx meeting recordings that have been recorded on the computer of an on-line meeting attendee. The WRF Player is an application that is used to play back and edit WRF files (files with .wrf extensions). The WRF Player can be automatically installed when the user accesses a WRF file that is hosted on a WebEx server (stream playback mode). The WRF Player can also be manually installed after downloading the application from www.webex.com to play back WRF files locally (offline playback mode). Multiple buffer overflow vulnerabilities exist in the WRF Player. The vulnerabilities may lead to a crash of the WRF Player application, or in some cases, lead to remote code execution. To exploit a vulnerability, a malicious WRF file would need to be opened by the WRF Player application. An attacker may be able to accomplish this by providing the malicious WRF file directly to users (for example, via e-mail), or by convincing users to visit a malicious website. The vulnerability cannot be triggered by users attending a WebEx meeting. These vulnerabilities have been assigned the following Common Vulnerabilities and Exposures (CVE) identifiers: * CVE-2009-2875 * CVE-2009-2876 * CVE-2009-2877 * CVE-2009-2878 * CVE-2009-2879 * CVE-2009-2880 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 * Multiple Cisco WebEx Player Buffer Overflow Vulnerabilities (all vulnerabilities in this advisory) CVSS Base Score - 9.3 Access Vector - Network Access Complexity - Medium Authentication - None Confidentiality Impact - Complete Integrity Impact - Complete Availability Impact - Complete CVSS Temporal Score - 7.7 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed Impact ====== Successful exploitation of the vulnerabilities described in this document could result in a crash of the Cisco WebEx WRF Player application, and in some cases, allow a remote attacker to execute arbitrary code on the targeted system with the privileges of the user running the WRF Player application.

The Cisco WebEx WRF Player is an application that is used to play back WebEx meeting recordings that have been recorded on the computer of an on-line meeting attendee. The WRF Player can be automatically installed when the user accesses a WRF file that is hosted on a WebEx server. The WRF Player can also be manually installed for offline playback after downloading the application from www.webex.com. If the WRF Player was automatically installed, the WebEx WRF Player will be automatically upgraded to the latest, non-vulnerable version when users access a WRF file hosted on a WebEx server. If the WebEx WRF Player was manually installed, users will need to manually install a new version of the player after downloading the latest version from www.webex.com. Cisco has released free software updates that address these vulnerabilities. This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20091216-webex.shtml. Affected Products ================= Vulnerable Products - ------------------- The vulnerabilities disclosed in this advisory affect the Cisco WebEx WRF Player. Microsoft Windows, Apple Mac OS X, and Linux versions of the player are affected. Affected versions of the WRF Player are those prior to the "first fixed" versions, which are shown in the section "Software Versions and Fixes" of this advisory. To check if a Cisco WebEx server is running an affected version of the WebEx client build, users can log in to their Cisco WebEx server and go to the Support -> Downloads section. The version of the WebEx client build will be displayed on the right-hand side of the page under "About Support Center", for example "Client build: 27.11.0.3328". There is no way to check if a manually installed version of the WRF Player is affected by these vulnerabilities. Therefore, Cisco recommends that users upgrade to the most current version of the player that is available from http://www.webex.com/downloadplayer.html. Products Confirmed Not Vulnerable - --------------------------------- The Cisco WebEx Player for the WebEx Advanced Recording Format (ARF) file format is not affected by these vulnerabilities. No other Cisco products are currently known to be affected by these vulnerabilities. Details ======= The WebEx meeting service is a hosted multimedia conferencing solution that is managed by and maintained by Cisco WebEx. The WebEx Recording Format (WRF) is a file format that is used to store WebEx meeting recordings that have been recorded on the computer of an on-line meeting attendee.

The Cisco WebEx WRF Player is an application that is used to play back WebEx meeting recordings that have been recorded on the computer of an on-line meeting attendee. The WRF Player can be automatically installed when the user accesses a WRF file that is hosted on a WebEx server. The WRF Player can also be manually installed for offline playback after downloading the application from www.webex.com. If the WRF Player was automatically installed, the WebEx WRF Player will be automatically upgraded to the latest, non-vulnerable version when users access a WRF file hosted on a WebEx server. If the WebEx WRF Player was manually installed, users will need to manually install a new version of the player after downloading the latest version from www.webex.com. Cisco has released free software updates that address these vulnerabilities. This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20091216-webex.shtml. Affected Products ================= Vulnerable Products - ------------------- The vulnerabilities disclosed in this advisory affect the Cisco WebEx WRF Player. Microsoft Windows, Apple Mac OS X, and Linux versions of the player are affected. Affected versions of the WRF Player are those prior to the "first fixed" versions, which are shown in the section "Software Versions and Fixes" of this advisory. To check if a Cisco WebEx server is running an affected version of the WebEx client build, users can log in to their Cisco WebEx server and go to the Support -> Downloads section. The version of the WebEx client build will be displayed on the right-hand side of the page under "About Support Center", for example "Client build: 27.11.0.3328". There is no way to check if a manually installed version of the WRF Player is affected by these vulnerabilities. Therefore, Cisco recommends that users upgrade to the most current version of the player that is available from http://www.webex.com/downloadplayer.html. Products Confirmed Not Vulnerable - --------------------------------- The Cisco WebEx Player for the WebEx Advanced Recording Format (ARF) file format is not affected by these vulnerabilities. No other Cisco products are currently known to be affected by these vulnerabilities. Details ======= The WebEx meeting service is a hosted multimedia conferencing solution that is managed by and maintained by Cisco WebEx. The WebEx Recording Format (WRF) is a file format that is used to store WebEx meeting recordings that have been recorded on the computer of an on-line meeting attendee. The WRF Player is an application that is used to play back and edit WRF files (files with .wrf extensions). The WRF Player can be automatically installed when the user accesses a WRF file that is hosted on a WebEx server (stream playback mode). The WRF Player can also be manually installed after downloading the application from www.webex.com to play back WRF files locally (offline playback mode). The vulnerabilities may lead to a crash of the WRF Player application, or in some cases, lead to remote code execution. To exploit a vulnerability, a malicious WRF file would need to be opened by the WRF Player application. An attacker may be able to accomplish this by providing the malicious WRF file directly to users (for example, via e-mail), or by convincing users to visit a malicious website. The vulnerability cannot be triggered by users attending a WebEx meeting. These vulnerabilities have been assigned the following Common Vulnerabilities and Exposures (CVE) identifiers: * CVE-2009-2875 * CVE-2009-2876 * CVE-2009-2877 * CVE-2009-2878 * CVE-2009-2879 * CVE-2009-2880 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 * Multiple Cisco WebEx Player Buffer Overflow Vulnerabilities (all vulnerabilities in this advisory) CVSS Base Score - 9.3 Access Vector - Network Access Complexity - Medium Authentication - None Confidentiality Impact - Complete Integrity Impact - Complete Availability Impact - Complete CVSS Temporal Score - 7.7 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed Impact ====== Successful exploitation of the vulnerabilities described in this document could result in a crash of the Cisco WebEx WRF Player application, and in some cases, allow a remote attacker to execute arbitrary code on the targeted system with the privileges of the user running the WRF Player application.

Multiple cross-site request forgery (CSRF) vulnerabilities on the Network Management Card (NMC) on American Power Conversion (APC) Switched Rack PDU (aka Rack Mount Power Distribution) devices and other devices allow remote attackers to hijack the authentication of (1) administrator or (2) device users for requests that create new administrative users or have unspecified other impact. The web management interface for the APC Network Monitoring Card (NMC) used in various APC devices contains cross-site scripting (XSS) and cross-site request forgery (CSRF/XSRF) vulnerabilities. By convincing a victim to load a specially crafted URL while authenticated to an NMC, an attacker could obtain credentials or perform certain actions as the victim, including turning off the NMC-based device and any systems attached to it. An attacker can exploit the cross-site request forgery issues to alter the settings on affected devices, which may lead to further network-based attacks. The attacker can exploit the cross-site scripting issues to execute arbitrary script code in the context of the affected browser, potentially allowing the attacker to steal cookie-based authentication credentials. Other attacks are also possible. Versions prior to the following are vulnerable: Network Management Card Firmware 3.7.2 Network Management Card Firmware 5.1.1. ---------------------------------------------------------------------- Do you have VARM strategy implemented? (Vulnerability Assessment Remediation Management) If not, then implement it through the most reliable vulnerability intelligence source on the market.

I. Description Adobe Security Advisory APSB10-02 describes a number of vulnerabilities affecting Adobe Reader and Acrobat. These vulnerabilities affect Reader 9.2 and earlier 9.x versions and 8.1.7 and earlier 8.x versions. Further details are available in the US-CERT Vulnerability Notes Database. An attacker could exploit these vulnerabilities by convincing a user to open a specially crafted PDF file. The Adobe Reader browser plug-in is available for multiple web browsers and operating systems, which can automatically open PDF documents hosted on a website. Some of these vulnerabilities are being actively exploited. II. III. Solution Update Adobe has released updates to address this issue. Users are encouraged to read Adobe Security Bulletin APSB10-02 and update vulnerable versions of Adobe Reader and Acrobat. Acrobat JavaScript can be disabled using the Preferences menu (Edit -> Preferences -> JavaScript; un-check Enable Acrobat JavaScript). Prevent Internet Explorer from automatically opening PDF documents The installer for Adobe Reader and Acrobat configures Internet Explorer to automatically open PDF files without any user interaction. This behavior can be reverted to a safer option that prompts the user by importing the following as a .REG file: Windows Registry Editor Version 5.00 [HKEY_CLASSES_ROOT\AcroExch.Document.7] "EditFlags"=hex:00,00,00,00 Disable the display of PDF documents in the web browser Preventing PDF documents from opening inside a web browser will partially mitigate this vulnerability. If this workaround is applied it may also mitigate future vulnerabilities. To prevent PDF documents from automatically being opened in a web browser, do the following: 1. Open Adobe Acrobat Reader. 2. Open the Edit menu. 3. Choose the preferences option. 4. Choose the Internet section. 5. Un-check the "Display PDF in browser" check box. Do not access PDF documents from untrusted sources Do not open unfamiliar or unexpected PDF documents, particularly those hosted on websites or delivered as email attachments.

Adobe Reader and Acrobat 9.x before 9.3, and 8.x before 8.2 on Windows and Mac OS X, might allow attackers to cause a denial of service (NULL pointer dereference) via unspecified vectors. The Doc.media.newPlayer method in Adobe Acrobat and Reader contains a use-after-free vulnerability, which may allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system. Adobe Reader and Acrobat are prone to a denial-of-service vulnerability. Successfully exploiting this issue may allow attackers to crash the affected applications, denying service to legitimate users. NOTE: This issue was previously covered in BID 37667 (Adobe Acrobat and Reader January 2010 Multiple Remote Vulnerabilities), but has been given its own record to better document it. ---------------------------------------------------------------------- Do you have VARM strategy implemented?

The default configuration of Adobe Reader and Acrobat 9.x before 9.3, and 8.x before 8.2 on Windows and Mac OS X, does not enable the Enhanced Security feature, which has unspecified impact and attack vectors, related to a "script injection vulnerability," as demonstrated by Acrobat Forms Data Format (FDF) behavior that allows cross-site scripting (XSS) by user-assisted remote attackers. The Doc.media.newPlayer method in Adobe Acrobat and Reader contains a use-after-free vulnerability, which may allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system. An attacker can exploit this issue to obtain the contents of sensitive PDF files or to perform cross-site scripting attacks against domains hosting PDF files.

Adobe Reader and Acrobat 9.x before 9.3, and 8.x before 8.2 on Windows and Mac OS X, allows remote attackers to execute arbitrary code via a crafted JPC_MS_RGN marker in the Jp2c stream of a JpxDecode encoded data stream, which triggers an integer sign extension that bypasses a sanity check, leading to memory corruption. The Doc.media.newPlayer method in Adobe Acrobat and Reader contains a use-after-free vulnerability, which may allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system. Adobe Reader and Acrobat are prone to a memory-corruption vulnerability. An attacker can exploit this issue to execute arbitrary code. Failed exploit attempts will likely cause denial-of-service conditions. This issue affects Reader and Acrobat 9.2 and prior versions. NOTE: This issue was previously covered in BID 37667 (Adobe Acrobat and Reader January 2010 Multiple Remote Vulnerabilities), but has been given its own record to better document it. iDefense Security Advisory 01.12.10 http://labs.idefense.com/intelligence/vulnerabilities/ Jan 12, 2010 I. For more information, please visit following pages: http://www.adobe.com/products/reader/ http://www.adobe.com/products/acrobat/ II. The vulnerability occurs when processing the Jp2c stream of a JpxDecode encoded data stream within a PDF file. During the processing of a JPC_MS_RGN marker, an integer sign extension may cause a bounds check to be bypassed. This results in an exploitable memory corruption vulnerability. III. The attacker will have to create a malicious PDF file and convince the victim to open it. This can be accomplished by embedding the PDF file into an IFrame inside of a Web page, which will result in automatic exploitation once the page is viewed. The file could also be e-mailed as an attachment or placed on a file share. In these cases, a user would have to manually open the file to trigger exploitation. If preview is enabled in Windows Explorer, Acrobat will try to generate a preview for PDF files when a folder containing PDF files is accessed, thus triggering the exploitation. IV. DETECTION iDefense has confirmed the existence of this vulnerability in latest version of Adobe Reader, at the time of testing, version 9.1.0. Previous versions may also be affected. Adobe has stated that all 9.2 and below versions, as well as all 8.1.7 and below versions are vulnerable. V. WORKAROUND None of the following workarounds will prevent exploitation, but they can reduce potential attack vectors and make exploitation more difficult. Prevent PDF documents from being opened automatically by the Web browser Disable JavaScript Disable PDFShell extension by removing or renaming the Acrord32info.exe file VI. VENDOR RESPONSE Adobe has released a patch which addresses this issue. Information about downloadable vendor updates can be found by clicking on the URLs shown. http://www.adobe.com/support/security/bulletins/apsb10-02.html VII. CVE INFORMATION The Common Vulnerabilities and Exposures (CVE) project has assigned the name CVE-2009-3955 to this issue. This is a candidate for inclusion in the CVE list (http://cve.mitre.org/), which standardizes names for security problems. VIII.

Intellicom NetBiter WebSCADA devices use default passwords for the HICP network configuration service, which makes it easier for remote attackers to modify network settings and cause a denial of service. NOTE: this is only a vulnerability when the administrator does not follow recommendations in the product's installation documentation. NOTE: this issue was originally reported to be hard-coded passwords, not default passwords. The IntelliCom NetBiter Config HICP configuration utility has a buffer overflow vulnerability that can be triggered by a specially crafted hostname (hn) value. An attacker with network access could exploit this vulnerability to execute arbitrary code with the privileges of the user running NetBiter Config. IntelliCom Provided by NetBiter The password set on the device at the factory may be used by a remote third party. IntelliCom Provided by NetBiter The device is Ethernet and IP To configure network settings HICP The protocol is used. NetBiter The device is factory set HICP The password for can be obtained by methods other than the product documentation.Without changing from the factory password NetBiter When operating the device, the remote third party who obtained the password may change the network settings or change the password. HICP Access to the service may be disrupted. Also, HICP Since passwords are transmitted in clear text, the password may be intercepted by a third party intercepting the communication. Successful exploits may allow attackers to gain privileged access to the device or network; other attacks may also be possible. NOTE: This BID is being retired as it has been determined to not be a vulnerability. The default password and instructions on changing it are detailed in the product documentation. Netbiter Webscada Firmware is prone to a denial-of-service vulnerability

Stack-based buffer overflow in the NetBiterConfig utility (NetBiterConfig.exe) 1.3.0 for Intellicom NetBiter WebSCADA allows remote attackers to execute arbitrary code via a long hn (hostname) parameter in a crafted HICP-protocol UDP packet. IntelliCom NetBiter devices ship with default passwords for the HICP network configuration service. An attacker with network access could exploit this vulnerability to execute arbitrary code with the privileges of the user running NetBiter Config. Successful exploits may allow attackers to gain privileged access to the device or network; other attacks may also be possible. NOTE: This BID is being retired as it has been determined to not be a vulnerability. The default password and instructions on changing it are detailed in the product documentation. Intellicom 'NetBiterConfig.exe' is prone to a remote stack-based buffer-overflow vulnerability because the application fails to perform adequate boundary checks on user-supplied data. Failed exploit attempts will result in a denial-of-service condition
