Multiple SQL injection vulnerabilities in Fiyo CMS 2.0_1.9.1 allow remote attackers to execute arbitrary SQL commands via the (1) id parameter to apps/app_article/controller/rating.php or (2) user parameter to user/login.

• → Monitor POST requests to rating.php containing semicolons or SQL keywords (e.g., SELECT, SLEEP) in the 'id' parameter, indicative of time-based blind SQLi exploitation. ↗
• → Monitor POST requests to the login endpoint where the 'user' parameter contains SQL time-delay payloads using nested SELECT/SLEEP constructs, bypassing strip_tags(). ↗
• → Detect exploitation of rating.php by checking for a Referer header pointing to the application root, which is required to bypass authority checks in jscore.php. ↗
• → The 'id' parameter in POST body to rating.php is passed unsanitized directly into a SQL SELECT query; alert on non-numeric or SQL-containing values in this field. ↗
• → The 'user' parameter in the login POST body is only sanitized with strip_tags(), which does not prevent SQL injection; alert on SQL metacharacters (quotes, plus signs, parentheses) in this field. ↗

• · Both SQL injection vectors require POST method; GET-based scanning will not trigger these vulnerabilities. ↗
• · Exploitation of the rating.php vector requires a valid Referer header matching the application root to pass the jscore.php authority check; requests without a proper Referer will be rejected before reaching the vulnerable code. ↗
• · Affects only Fiyo CMS version 2.0_1.9.1; other versions are not confirmed vulnerable. ↗
