Critical

AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Name of the Vulnerable Software and Affected Versions vBulletin versions 5.0.0 through 5.5.4
Description The issue is related to errors in code generation management, allowing a remote attacker to execute arbitrary commands using a specially crafted widgetConfig[code] parameter in an ajax/render/widget php routestring request. This can be done without authentication. The vulnerability affects many open projects, including forums for Ubuntu, openSUSE, BSD systems, and Slackware.
Recommendations For versions 5.0.0 through 5.5.4, consider disabling the widget php function or restricting access to the ajax/render/widget php endpoint until a patch is available. Avoid using the widgetConfig[code] parameter in the affected API endpoint until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
