sre/params.php in the Integrity Clientless Security (ICS) component in Check Point Connectra NGX R62 3.x and earlier before Security Hotfix 5, and possibly VPN-1 NGX R62, allows remote attackers to bypass security requirements via a crafted Report parameter, which returns a valid ICSCookie authentication token.

Multiple cross-site scripting (XSS) vulnerabilities in F5 FirePass SSL VPN allow remote attackers to inject arbitrary web script or HTML via (1) the xcho parameter to my.logon.php3; the (2) topblue, (3) midblue, (4) wtopblue, and certain other Custom color parameters in a per action to vdesk/admincon/index.php; the (5) h321, (6) h311, (7) h312, and certain other Front Door custom text color parameters in a per action to vdesk/admincon/index.php; the (8) ua parameter in a bro action to vdesk/admincon/index.php; the (9) app_param and (10) app_name parameters to webyfiers.php; (11) double eval functions; (12) JavaScript contained in an <FP_DO_NOT_TOUCH> element; and (13) the vhost parameter to my.activation.php. NOTE: it is possible that this candidate overlaps CVE-2006-3550.

The VPN service in Apple Mac OS X 10.3.x through 10.3.9 and 10.4.x through 10.4.8 does not properly clean the environment when executing commands, which allows local users to gain privileges via unspecified vectors.

SSL VPN Client in Cisco Secure Desktop before 3.1.1.45, when configured to spawn a web browser after a successful connection, stores sensitive browser session information in a directory outside of the CSD vault and does not restrict the user from saving files outside of the vault, which is not cleared after the VPN connection terminates and allows local users to read unencrypted data.

Cross-site scripting (XSS) vulnerability in my.acctab.php3 in F5 Networks FirePass 1000 SSL VPN 5.5, and possibly earlier, allows remote attackers to inject arbitrary web script or HTML via the sid parameter.

Cisco Secure Desktop (CSD) does not require that the ClearPageFileAtShutdown (aka CCE-Winv2.0-407) registry value equals 1, which might allow local users to read certain memory pages that were written during another user's SSL VPN session.

The default configuration of Cisco Secure Desktop (CSD) has an unchecked "Disable printing" box in Secure Desktop Settings, which might allow local users to read data that was sent to a printer during another user's SSL VPN session.

Intoto iGateway VPN and iGateway SSL-VPN allow context-dependent attackers to cause a denial of service (CPU consumption) via parasitic public keys with large (1) "public exponent" or (2) "public modulus" values in X.509 certificates that require extra time to process when using RSA signature verification, a related issue to CVE-2006-2940.

Multiple unspecified vulnerabilities in Cisco VPN 3000 series concentrators before 4.1, 4.1.x up to 4.1(7)L, and 4.7.x up to 4.7(2)F allow attackers to execute the (1) CWD, (2) MKD, (3) CDUP, (4) RNFR, (5) SIZE, and (6) RMD FTP commands to modify files or create and delete directories via unknown vectors.

Internet Key Exchange (IKE) version 1 protocol, as implemented on Cisco IOS, VPN 3000 Concentrators, and PIX firewalls, allows remote attackers to cause a denial of service (resource exhaustion) via a flood of IKE Phase-1 packets that exceed the session expiration rate. NOTE: it has been argued that this is due to a design weakness of the IKE version 1 protocol, in which case other vendors and implementations would also be affected.

NCP Secure Enterprise Client (aka VPN/PKI client) 8.30 Build 59, and possibly earlier versions, when the Link Firewall and Personal Firewall are both configured to block all inbound and outbound network traffic, allows context-dependent attackers to send inbound UDP traffic with source port 67 and destination port 68, and outbound UDP traffic with source port 68 and destination port 67.

Buffer overflow in the Online Registration Facility for Algorithmic Research PrivateWire VPN software up to 3.7 allows remote attackers to execute arbitrary code via a long GET request.

Multiple cross-site scripting (XSS) vulnerabilities in the WebVPN feature in the Cisco VPN 3000 Series Concentrators and Cisco ASA 5500 Series Adaptive Security Appliances (ASA), when in WebVPN clientless mode, allow remote attackers to inject arbitrary web script or HTML via the domain parameter in (1) dnserror.html and (2) connecterror.html, aka bugid CSCsd81095 (VPN3k) and CSCse48193 (ASA). NOTE: the vendor states that "WebVPN full-network-access mode" is not affected, despite the claims by the original researcher.

Unspecified vulnerability in the VPN Client for Windows Graphical User Interface (GUI) (aka the VPN client dialer) in Cisco VPN Client for Windows 4.8.00.* and earlier, except for 4.7.00.0533, allows local authenticated, interactive users to gain privileges, possibly due to privileges of dialog boxes, aka bug ID CSCsd79265.

Cross-site scripting (XSS) vulnerability in my.support.php3 in F5 Firepass 4100 SSL VPN 5.4.2 allows remote attackers to inject arbitrary web script or HTML via the s parameter.

IPSec when used with VPN networks in Mac OS X 10.4 through 10.4.5 allows remote attackers to cause a denial of service (application crash) via unspecified vectors involving the "incorrect handling of error conditions".

Cisco VPN 3000 series concentrators running software 4.7.0 through 4.7.2.A allow remote attackers to cause a denial of service (device reload or user disconnect) via a crafted HTTP packet.

Linksys BEFVP41 VPN Router 2.0 with firmware 1.01.04 allows remote attackers on the local network, to cause a denial of service via IP packets with a null IP option length.

Unquoted Windows search path vulnerability in Check Point VPN-1 SecureClient might allow local users to gain privileges via a malicious "program.exe" file in the C: folder, which is run when SecureClient attempts to launch the Sr_GUI.exe program.

Avaya VPNRemote before 4.2.33 stores credentials in cleartext in process memory, which allows attackers to obtain the VPN user's credentials.
