CyberRota Analysis
AI-GeneratedvBulletin versions 5.x (up to 5.7.5) and 6.x (up to 6.2.1) are vulnerable to a critical eval injection flaw that enables unauthenticated remote attackers to execute arbitrary PHP code through the pagenav[pagenumber] parameter. This vulnerability arises from an insufficiently restrictive regex filter, allowing attackers to bypass security measures using crafted input. Organizations using affected vBulletin versions should prioritize immediate remediation to mitigate the risk of unauthorized code execution and potential system compromise.

Original NVD Description
vBulletin 5.x through 5.7.5 and 6.x through 6.2.1 contains an eval injection vulnerability in the vB5_Template_Runtime::runMaths() method within the template runtime that allows unauthenticated remote attackers to execute arbitrary PHP code by supplying crafted input through the pagenav[pagenumber] parameter. Attackers can exploit the insufficiently restrictive regex filter by using phpfuck-style encoding with permitted characters to inject and execute arbitrary PHP code via the unauthenticated ajax/render template route without any authentication.
