Summary

PHP remote file inclusion vulnerability in install/upgrade_301.php in Jelsoft vBulletin 3.5.4 allows remote attackers to execute arbitrary PHP code via the step parameter. The vendor has disputed this vulnerability, stating that the default vBulletin requires authentication prior to using the upgrade system.

Risk Assessment

If the vulnerability is real, an attacker could execute arbitrary PHP code on the server, leading to full system compromise. However, the vendor claims authentication is required, which significantly limits the risk in default configurations.

Recommendation

Ensure that the vBulletin upgrade system is protected by authentication and not accessible to unauthenticated users. It is also recommended to upgrade to the latest vBulletin version if possible.
