Cross-site scripting (XSS) vulnerability in the View URL Database functionality in Sun Java System Web Proxy Server 4.x before 4.0.6 and 3.x before 3.6 SP11 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors, aka BugID 6566309.

The connection log file implementation in Grok Developments NetProxy 4.03 does not record requests that omit http:// in a URL, which might allow remote attackers to conduct unauthorized activities and avoid detection.

Grok Developments NetProxy 4.03 allows remote attackers to bypass URL filtering via a request that omits "http://" from the URL and specifies the destination port (:80).

HTTP request smuggling vulnerability in Sun Java System Proxy Server before 20061130, when used with Sun Java System Application Server or Sun Java System Web Server, allows remote attackers to bypass HTTP request filtering, hijack web sessions, perform cross-site scripting (XSS), and poison web caches via unspecified attack vectors.

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.

Buffer overflow in BlueCoat (a) WinProxy before 6.1a and (b) the web console access functionality in ProxyAV before 2.4.2.3 allows remote attackers to execute arbitrary code via a long Host: header.

Cross-site scripting (XSS) vulnerability in IBM Web Traffic Express Caching Proxy Server 3.6 and 4.x before 4.0.1.26 allows remote attackers to execute script as other users via an HTTP request that contains an Location: header with a "%0a%0d" (CRLF) sequence, which echoes the Location as an HTTP header in the server response.

IBM Web Traffic Express Caching Proxy Server 3.6 and 4.x before 4.0.1.26 allows remote attackers to cause a denial of service (crash) via an HTTP request to helpout.exe with a missing HTTP version number, which causes ibmproxy.exe to crash.

Cross-site scripting (XSS) vulnerability in IBM Web Traffic Express Caching Proxy Server 3.6 and 4.x before 4.0.1.26 allows remote attackers to execute script as other users via an HTTP GET request.

Buffer overflows in AnalogX Proxy before 4.12 allows remote attackers to cause a denial of service and possibly execute arbitrary code via (1) a long HTTP request to TCP port 6588 or (2) a SOCKS 4A request to TCP port 1080 with a long DNS hostname.
