## Technical details

A SQL injection vulnerability exists in EyouCMS versions up to and including 1.7.1. The flaw is located in the API component within the /index.php file (specifically the get_ask_details method). The root cause is improper neutralization of the 'click_like' parameter, which allows an attacker to inject malicious SQL statements such as 'extractvalue' payloads. While the attack can be executed remotely, the CVSS vector suggests high privileges (PR:H) may be required. A public exploit has been disclosed, but as of the advisory date, the vendor has not released a formal patch.
