Multiple vulnerabilities were identified in Invision Power Board (IPB), which could be exploited by remote attackers to execute arbitrary commands, or perform SQL injection and cross site scripting.
The first issue is due to an input validation error when displaying uploaded JPEG images with headers containing HTML code, which could be exploited by attackers to cause malicious scripting code to be executed by the user's browser.
The second flaw is due to an input validation error in the "index.php" script that fails to properly validate the "ck" parameter, which could be exploited by malicious people to conduct SQL injection attacks.
The third vulnerability is due to an input validation error in the "search.php" script that does not validate the "lastdate" parameter before being passed to a "preg_replace()" call, which may be exploited by remote attackers to inject and execute arbitrary commands with the privileges of the web server.
The fourth flaw is due to an input validation error in the "admin.php" script that does not validate the "name" parameter, which could be exploited by remote attackers to include malicious scripts and execute arbitrary commands with the privileges of the web server.
