A certain Java applet in the VPN downloader implementation in the WebLaunch feature in Cisco AnyConnect Secure Mobility Client 3.x before 3.0 MR7 on 64-bit Linux platforms does not properly restrict use of Java components, which allows remote attackers to execute arbitrary code via a crafted web site, aka Bug ID CSCty45925.

The VPN downloader implementation in the WebLaunch feature in Cisco AnyConnect Secure Mobility Client 2.x before 2.5 MR6 and 3.x before 3.0 MR8 does not compare the timestamp of offered software to the timestamp of installed software, which allows remote attackers to force a version downgrade by using (1) ActiveX or (2) Java components to offer signed code that corresponds to an older software release, aka Bug ID CSCtw48681.

The VPN downloader implementation in the WebLaunch feature in Cisco AnyConnect Secure Mobility Client 2.x before 2.5 MR6 on Windows, and 2.x before 2.5 MR6 and 3.x before 3.0 MR8 on Mac OS X and Linux, does not properly validate binaries that are received by the downloader process, which allows remote attackers to execute arbitrary code via vectors involving (1) ActiveX or (2) Java components, aka Bug ID CSCtw47523.

Untrusted search path vulnerability in TrGUI.exe in the Endpoint Connect (aka EPC) GUI in Check Point Endpoint Security R73.x and E80.x on the VPN blade platform, Endpoint Security VPN R75, Endpoint Connect R73.x, and Remote Access Clients E75.x allows local users to gain privileges via a Trojan horse DLL in the current working directory.

Cisco Adaptive Security Appliances (ASA) 5500 series devices with software 8.2 through 8.4 process IKE requests despite a vpnclient mode configuration, which allows remote attackers to obtain potentially sensitive information by reading IKE responder traffic, aka Bug ID CSCtt07749.

Buffer overflow in the Cisco Port Forwarder ActiveX control in cscopf.ocx, as distributed through the Clientless VPN feature on Cisco Adaptive Security Appliances (ASA) 5500 series devices with software 7.0 through 7.2 before 7.2(5.6), 8.0 before 8.0(5.26), 8.1 before 8.1(2.53), 8.2 before 8.2(5.18), 8.3 before 8.3(2.28), 8.2 before 8.4(2.16), and 8.6 before 8.6(1.1), allows remote attackers to execute arbitrary code via unspecified vectors, aka Bug ID CSCtr00165.

Format string vulnerability in VPN in Apple iOS before 5.1 allows remote attackers to execute arbitrary code via a crafted racoon configuration file.

The modify_resolvconf_suse script in the vpnc package before 0.5.1-55.10.1 in SUSE Linux Enterprise Desktop 11 SP1 might allow remote attackers to execute arbitrary commands via a crafted DNS domain name.

The Cisco VPN Client 5.0.7.0240 and 5.0.7.0290 on 64-bit Windows platforms uses weak permissions (NT AUTHORITY\INTERACTIVE:F) for cvpnd.exe, which allows local users to gain privileges by replacing this executable file with an arbitrary program, aka Bug ID CSCtn50645. NOTE: this vulnerability exists because of a CVE-2007-4415 regression.

The Start Before Logon (SBL) functionality in Cisco AnyConnect Secure Mobility Client (formerly AnyConnect VPN Client) before 2.3.254 on Windows, and on Windows Mobile, allows local users to gain privileges via unspecified user-interface interaction, aka Bug ID CSCta40556.

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 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 Connection Manager in IBM Lotus Mobile Connect before 6.1.4 does not properly maintain a certain reference count, which allows remote authenticated users to cause a denial of service (IP address exhaustion) by making invalid attempts to establish sessions with the same VPN ID from multiple devices.

The remote-access IPSec VPN implementation on Cisco Adaptive Security Appliances (ASA) 5500 series devices, PIX Security Appliances 500 series devices, and VPN Concentrators 3000 series devices responds to an Aggressive Mode IKE Phase I message only when the group name is configured on the device, which allows remote attackers to enumerate valid group names via a series of IKE negotiation attempts, aka Bug ID CSCtj96108, a different vulnerability than CVE-2005-2025.

Unspecified vulnerability in OpenConnect before 2.23 allows remote AnyConnect SSL VPN servers to cause a denial of service (application crash) via a 404 HTTP status code.
