Description
directory.php in AJchat 0.10 allows remote attackers to bypass input validation and conduct SQL injection attacks via a numeric parameter with a value matching the s parameter's hash value, which prevents the associated $_GET["s"] variable from being unset. NOTE: it could be argued that this vulnerability is due to a bug in the unset PHP command (CVE-2006-3017) and the proper fix should be in PHP; if so, then this should not be treated as a vulnerability in AJChat.
Public exploits
Exploit or proof-of-concept code for this vulnerability is publicly available, which lowers the bar for attackers. Treat it as a reason to patch sooner.
Third-party code, not reviewed by us. Public PoCs are sometimes fake or contain malware. Read the code first and run it only in an isolated lab, against systems you are authorised to test.
