SQL injection vulnerability in users.asp in QuadComm Q-Shop 3.0, and possibly earlier, allows remote attackers to execute arbitrary SQL commands via the (1) UserID and (2) Pwd parameters. NOTE: this might be related to CVE-2004-2108.
Improper Neutralization of Special Elements used in an SQL Command 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. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
