Detailed Description

Business Impact: As evident with the number of web-related vulnerabilities and this year's relentless attacks on Web servers using SQL injection and other methods, vulnerabilities affecting web servers are becoming increasingly lucrative targets for attackers.  In addition to compromising the targeted web server, these attacks are used to plant other exploits, malware, or redirects to malicious web servers essentially turning a trusted domain into an attack center for the true target: endpoints (the customers and employees that use the target website).

Technical Description:

Oracle WebLogic Server (formerly known as BEA WebLogic Server) is vulnerable to a buffer overflow, caused by improper bounds checking by the Apache Connector. By sending a specially-crafted HTTP request, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the server to crash.
