Other vulnerabilities in vBulletin
See all- CVE-2017-7569High

- CVE-2026-61511Critical
vBulletin versions 5.x through 5.7.5 and 6.x through 6.2.1 contain an eval injection vulnerability in the vB5_Template_Runtime::runMaths() method, allowing unauthenticated remote attackers to execute arbitrary PHP code via crafted pagenav[pagenumber] parameter.
- CVE-2017-17672Critical
In vBulletin versions up to 5.3.x, there is an unauthenticated deserialization vulnerability that can lead to arbitrary file deletion and, under certain circumstances, code execution.

- CVE-2017-17671Critical
vBulletin versions up to 5.3.x on Windows allows remote PHP code execution due to the accessibility of a require_once call with an unauthenticated request that can include directory traversal sequences to specify an arbitrary pathname. The blocking of ../ traversal does not apply to ..\, allowing for exploitation of this vulnerability.
