CVE-2008-6900

CVE-2008-6900 describes an unrestricted file upload vulnerability in the "Add Pen/Author Name" feature of AvailScript Article Script's addpen.php. This flaw allows remote authenticated users to upload and execute arbitrary code by providing a file with an executable extension, which can then be accessed directly in the 'photos/' directory. With a CVSS score of 6.5, this vulnerability is of medium severity, requiring authentication but having low attack complexity, potentially leading to partial compromise of confidentiality, integrity, and availability. While not listed in CISA's KEV catalog, exploit code is publicly available via ExploitDB (EDB-7456), though there is no evidence of active exploitation, Metasploit modules, or significant community discussion.
