Natterchat 1.12 stores sensitive information under the web root with insufficient access control, which allows remote attackers to download the database file via a direct request for natterchat112.mdb.

NatterChat 1.1 allows remote attackers to bypass authentication and gain administrator privileges to read or delete rooms and messages via a direct request to admin/home.asp.

NOTE: these issues might be resultant from XSS in SQL error messages.

Multiple SQL injection vulnerabilities in login.asp in NatterChat 1.1 and 1.12 allow remote attackers to execute arbitrary SQL commands via the (1) txtUsername parameter (aka Username) and (2) txtPassword parameter (aka Password) in a form generated by home.asp. NOTE: due to lack of details, it is not clear whether this is related to CVE-2004-2206.
