CVE-2006-4449 describes a cross-site scripting (XSS) vulnerability in MyBulletinBoard (MyBB) version 1.1.7 and potentially other versions, specifically within the attachment.php component. This flaw allows remote attackers to inject arbitrary web script or HTML by embedding URL-encoded JavaScript within a GIF image, which is then rendered by Internet Explorer. The vulnerability has a CVSS score of 5.1, indicating a medium severity due to its network-based attack vector, high access complexity, and partial impact on confidentiality, integrity, and availability. While there is no evidence of active exploitation or Metasploit/Nuclei modules, an ExploitDB entry (EDB-28429) exists, detailing multiple HTML injection vulnerabilities in MyBB 1.1.7. Community discussion and media coverage for this CVE are minimal.
