427BB Multiple SQL Injection and Cross Site Scripting Vulnerabilities


Description   Multiple vulnerabilities were identified in 427BB, which could be exploited by malicious users to perform SQL injection or cross site scripting attacks.
The first issue is due to an input validation error when processing a specially crafted "username", "authenticated" or "usertype" cookie parameter, which could be exploited by remote attackers to bypass the authentication procedure and gain unauthorized access to a vulnerable application.
The second flaw is due to an input validation error in "posts.php" when handling a message containing a specially crafted "URL" BBcode tag, which could be exploited by attackers to execute arbitrary scripting code by tricking users into clicking on a malicious link.
The third vulnerability is due to an input validation error in "showthread.php" when handling a specially crafted "ForumID" parameter, which may be exploited by malicious people to conduct SQL injection attacks.
