OS command injection vulnerability exists in WebProxy 1.7.8 and 1.7.9, which may allow a remote unauthenticated attacker to execute an arbitrary OS command with the privilege of the running web server. Note that the developer was unreachable, therefore, users should consider stop using WebProxy 1.7.8 and 1.7.9.

Directory traversal vulnerability in WebProxy version 1.7.8 allows an attacker to read arbitrary files via unspecified vectors.

Cross-site scripting (XSS) vulnerability in LunarNight Laboratory WebProxy 1.7.8 and earlier allows remote attackers to inject arbitrary web script or HTML via unspecified 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.

Heap-based buffer overflow in proxy_util.c for mod_proxy in Apache 1.3.25 to 1.3.31 allows remote attackers to cause a denial of service (process crash) and possibly execute arbitrary code via a negative Content-Length HTTP header field, which causes a large amount of data to be copied.

mod_digest_apple for Apache 1.3.31 and 1.3.32 on Mac OS X Server does not properly verify the nonce of a client response, which allows remote attackers to replay credentials.

HP Praesidium Webproxy 1.0 running on HP-UX 11.04 VVOS could allow remote attackers to cause Webproxy to forward requests to the internal network via crafted HTTP requests.
