BEA Web Logic plug-in for Apache JSESSION Cookie overflow

Summary: A buffer overflow exists in the Apache plug-in connector for BEA WebLogic, caused by an incorrectly bounded strncpy that copies the length of the JSESSIONID cookie value rather than the length of the fixed-size destination buffer on the stack. The flaw, tracked as CVE-2008-5457, was reported to Oracle on 10/22/08, detected by Snort/Sourcefire since 10/22/08 under SID 15010 GID 3, and patched by Oracle in its January 2009 CPU on 01/13/09.

Key Takeaway: The vulnerability is remotely exploitable without authentication and can affect the availability, confidentiality, or integrity of WebLogic applications fronted by the Apache plug-in, and the patch is only obtainable with an Oracle Support Account.
