The Filtering Service in Websense Web Security and Web Filter before 6.3.1 Hotfix 106 and 7.x before 7.1 allow remote attackers to cause a denial of service (filtering outage) via a crafted URL.

The ISAPI Filter plug-in in Websense Enterprise, Websense Web Security, and Websense Web Filter 6.3.3 and earlier, when used in conjunction with a Microsoft ISA or Microsoft Forefront TMG server, allows remote attackers to bypass intended filtering and monitoring activities for web traffic via an HTTP Via header.

The default configuration of Apache Tomcat in Websense Manager in Websense Web Security 7.0 and Web Filter 7.0 allows connections to TCP port 1812 from arbitrary source IP addresses, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via UTF-7 text to the 404 error page of a Project Woodstock service on this port.

The Remote Filtering component in Websense Web Security and Web Filter before 6.3.3 Hotfix 18 and 7.x before 7.1.1 allows remote attackers to cause a denial of service (daemon exit) via a large volume of traffic.

Websense Web Security and Web Filter before 6.3.3 Hotfix 27 and 7.x before 7.1.1 allow remote attackers to cause a denial of service (Blue Coat appliance integration outage) via a long URL.

The TRITON management console in Websense Web Security before 7.6 Hotfix 24 allows remote attackers to bypass authentication and read arbitrary reports via a crafted uid field, in conjunction with a crafted userRoles field, in a cookie, as demonstrated by a request to explorer_wse/favorites.exe.

Websense Web Security and Web Filter before 7.1 Hotfix 21 do not set the secure flag for the Encrypted Session (SSL) cookie in an https session, which makes it easier for remote attackers to capture this cookie by intercepting its transmission within an http session.

The default configuration of Apache Tomcat in Websense Manager in Websense Web Security 7.0 and Web Filter 7.0 enables weak SSL ciphers in conf/server.xml, which makes it easier for remote attackers to obtain sensitive information by sniffing the network and then conducting a brute-force attack against encrypted session data.

The Investigative Reports web interface in the TRITON management console in Websense Web Security 7.1 before Hotfix 109, 7.1.1 before Hotfix 06, 7.5 before Hotfix 78, 7.5.1 before Hotfix 12, 7.6 before Hotfix 24, and 7.6.2 before Hotfix 12; Web Filter; Web Security Gateway; and Web Security Gateway Anywhere allows remote attackers to execute commands via unspecified vectors.

The Remote Filtering component in Websense Web Security and Web Filter before 7.1 Hotfix 66 allows local users to bypass filtering by (1) renaming the WDC.exe file or (2) deleting driver files.
