Blue Coat Unified Agent before 4.6.2 does not prevent modification of its configuration files when running in local enforcement mode, which allows local administrators to unblock categories or disable the agent via unspecified vectors.

Blue Coat ProxyClient before 3.3.3.3 and 3.4.x before 3.4.4.10 and Unified Agent before 4.1.3.151952 does not properly validate certain certificates, which allows man-in-the-middle attackers to spoof ProxySG Client Managers, and consequently modify configurations and execute arbitrary software updates, via a crafted certificate.

The commandline interface in Blue Coat Content Analysis System (CAS) 1.1 before 1.1.4.2 allows remote administrators to execute arbitrary commands via unspecified vectors, related to "command injection."

The caching feature in SGOS in Blue Coat ProxySG 5.5 through 5.5.11.3, 6.1 through 6.1.6.3, 6.2 through 6.2.15.3, 6.4 through 6.4.6.1, and 6.3 and 6.5 before 6.5.4 allows remote authenticated users to bypass intended access restrictions during a time window after account deletion or modification by leveraging knowledge of previously valid credentials.

Blue Coat ProxySG before 6.2.14.1, 6.3.x, 6.4.x, and 6.5 before 6.5.2 allows remote attackers to cause a denial of service (memory consumption and dropped connections) via a recursive href in an HTML page, which triggers a large number of HTTP RW pipeline pre-fetch requests.

Directory traversal vulnerability in Blue Coat Reporter 9.x before 9.2.4.13, 9.2.5.x before 9.2.5.1, and 9.3 before 9.3.1.2 on Windows allows remote attackers to read arbitrary files, and consequently execute arbitrary code, via an unspecified HTTP request.

Blue Coat ProxySG 6.1 before SGOS 6.1.5.1 and 6.2 before SGOS 6.2.2.1 writes the secure heap to core images, which allows context-dependent attackers to obtain sensitive authentication information by leveraging read access to a downloaded core file.

Cross-site scripting (XSS) vulnerability in Blue Coat Director before 5.5.2.3 allows remote attackers to inject arbitrary web script or HTML via vectors involving the HTTP TRACE method.

Stack-based buffer overflow in the BCAAA component before build 60258, as used by Blue Coat ProxySG 4.2.3 through 6.1 and ProxyOne, allows remote attackers to execute arbitrary code via a large packet to the synchronization port (16102/tcp).

Cross-site scripting (XSS) vulnerability in the Java Management Console in Blue Coat ProxySG before SGOS 4.3.4.1, 5.x before SGOS 5.4.5.1, 5.5 before SGOS 5.5.4.1, and 6.x before SGOS 6.1.1.1 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

Multiple cross-site request forgery (CSRF) vulnerabilities on the Blue Coat ProxyAV appliance before 3.2.6.1 allow remote attackers to hijack the authentication of administrators for requests that (1) change a password, (2) modify a policy, or (3) restart the device.

The Active Content Transformation functionality in Blue Coat ProxySG before SGOS 4.3.4.2, 5.x before SGOS 5.4.5.1, 5.5 before SGOS 5.5.4.1, and 6.x before SGOS 6.1.2.1 allows remote attackers to bypass JavaScript detection via HTML entities.

Blue Coat ProxySG before SGOS 4.3.4.1, 5.x before SGOS 5.4.5.1, 5.5 before SGOS 5.5.4.1, and 6.x before SGOS 6.1.1.1 allows remote authenticated users to execute arbitrary CLI commands by leveraging read-only administrator privileges and establishing an HTTPS session.

Blue Coat ProxySG, when transparent interception mode is enabled, uses the HTTP Host header to determine the remote endpoint, which allows remote attackers to bypass access controls for Flash, Java, Silverlight, and probably other technologies, and possibly communicate with restricted intranet sites, via a crafted web page that causes a client to send HTTP requests with a modified Host header.

dne2000.sys in Citrix Deterministic Network Enhancer (DNE) 2.21.7.233 through 3.21.7.17464, as used in (1) Cisco VPN Client, (2) Blue Coat WinProxy, and (3) SafeNet SoftRemote and HighAssurance Remote, allows local users to gain privileges via a crafted DNE_IOCTL DeviceIoControl request to the \\.\DNE device interface.

Cross-site scripting (XSS) vulnerability in the ICAP patience page in Blue Coat Security Gateway OS (SGOS) 4.2 before 4.2.9, 5.2 before 5.2.5, and 5.3 before 5.3.1.7 allows remote attackers to inject arbitrary web script or HTML via the URL.

Buffer overflow in k9filter.exe in BlueCoat K9 Web Protection 3.2.36, and probably other versions before 3.2.44, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long HTTP GET request to port 2372.

Blue Coat Systems WinProxy 6.1a and 6.0 r1c, and possibly earlier, allows remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code via a long HTTP CONNECT request, which triggers heap corruption.

Blue Coat Proxy Security Gateway OS (SGOS) 4.1.2.1 does not enforce CONNECT rules when using Deep Content Inspection, which allows remote attackers to bypass connection filters.

Blue Coat Systems Inc. WinProxy before 6.1a allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a large number of packets with 0xFF characters to the Telnet port (TCP 23), which corrupts the heap.

The listening daemon in Blue Coat Systems Inc. WinProxy before 6.1a allows remote attackers to cause a denial of service (crash) via a long HTTP request that causes an out-of-bounds read.
