Sun Microsystems Inc's Java System is a collection of server applications bundled together. One such server application included is the Web Proxy Server. This software implements proxy services including HTTP and SOCKSv5.
For more information, visit http://www.sun.com/software/products/web_proxy/home_web_proxy.xml.
Remote exploitation of a heap based buffer overflow in Sun Microsystems Inc.'s Sun Java Web Proxy could allow an attacker to execute arbitrary code.
A heap based buffer overflow exists in the handling of FTP resources. Specifically the vulnerability resides within the code responsible for handling HTTP GET requests.
Exploitation of this issue allows an attacker to execute arbitrary code on the server. An attacker would need to locate the vulnerable server and construct a malicious HTTP GET request. The attacker would then send the HTTP GET request to the Sun Java Web Proxy Server and upon processing the request execution of arbitrary code would be possible.
Sun Java System Web Proxy Server 4.0 through 4.0.7 is vulnerable in the following versions:
SPARC Platform prior to patch 120981-15 x86 Platform prior to patch 120982-15 Linux prior to patch 120983-15 HP-UX prior to patch 123532-05 Windows prior to patch 126325-05
iDefense is currently unaware of any workarounds for this issue.
