CVE-2008-3423

20
FAUCET Score

CVE-2008-3423 describes an authentication bypass vulnerability in IBM WebSphere Portal versions 5.1 through 6.1.0.0, allowing remote attackers to gain administrative access. With a CVSS score of 7.5, this high-severity flaw has a low attack complexity and requires no authentication, potentially leading to full compromise of confidentiality, integrity, and availability. While no public exploit code or active exploitation has been observed, and community discussion is minimal, the vulnerability's age and the lack of readily available exploit intelligence suggest it is not a current high-priority threat.
