CWE Code: 89
Vulnerability Type: sql_injection
CVSS Score: 7.5
CWE Name:  Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Summary: 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.
