Technical details

IBM WebSphere Application Server is vulnerable to a privilege escalation flaw (CWE-306) within its administrative console. The root cause is a failure to require authentication for critical functions, allowing a remote, unauthenticated attacker to bypass access controls. By sending a specially crafted request over the network, an attacker can gain administrative rights, leading to a complete compromise of confidentiality, integrity, and availability. IBM has released interim fixes for APAR DT496500 and recommends upgrading to fix packs 9.0.5.29 or 8.5.5.31.
