Detailsinfo

A vulnerability was found in Ming Han AJchat 0.10 (Chat Software). It has been declared as critical. This vulnerability affects an unknown function of the file directory.php. The manipulation of the argument $_GET["s"] with an unknown input leads to a sql injection vulnerability. The CWE definition for the vulnerability is CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

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.
