PenPal contains a flaw that may allow an attacker to carry out an SQL injection attack. The issue is due to the 'login-verify.asp' script not properly sanitizing user-supplied input to the 'username" and 'password' variable. This may allow an attacker to inject or manipulate SQL queries in the backend database.
Currently, there are no known upgrades, patches, or workarounds available to correct this issue.
