Multiple SQL injection vulnerabilities in PHP Address Book 6.2.12 and earlier allow remote attackers to execute arbitrary SQL commands via the (1) to_group parameter to group.php or (2) id parameter to vcard.php. NOTE: the edit.php vector is already covered by CVE-2008-2565.
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.
