### [CVE-2004-0091](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2004-0091) ![](https://img.shields.io/static/v1?label=Product&message=n%2Fa&color=blue) ![](https://img.shields.io/static/v1?label=Version&message=n%2Fa&color=blue) ![](https://img.shields.io/static/v1?label=Vulnerability&message=n%2Fa&color=brighgreen) ### Description ** DISPUTED ** NOTE: this issue has been disputed by the vendor. Cross-site scripting (XSS) vulnerability in register.php for unknown versions of vBulletin allows remote attackers to inject arbitrary HTML or web script via the reg_site (or possibly regsite) parameter. NOTE: the vendor has disputed this issue, saying "There is no hidden field called 'reg_site', nor any $reg_site variable anywhere in the vBulletin 2 or vBulletin 3 source code or templates, nor has it ever existed. We can only assume that this vulnerability was found in a site running code modified from that supplied by Jelsoft." ### POC #### Reference - http://marc.info/?l=bugtraq&m=107462349324945&w=2 - http://marc.info/?l=vuln-dev&m=107462499927040&w=2 #### Github No PoCs found on GitHub currently.
