phpPgAds / phpAdsNew contains a flaw that may allow an attacker to carry out an SQL injection attack. The issue is due to the lib-view-direct.inc.php script not properly sanitizing user-supplied input to the 'clientid' variable. This may allow an attacker to inject or manipulate SQL queries in the back-end database.
Upgrade to version 2.0.6 or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
