• → Monitor HTTP GET requests to ForgotPassUserName.php containing SQL injection payloads in the 'u' parameter, specifically single-quote characters or OR-based boolean logic (e.g., ' OR '1'='1). ↗
• → The exploit targets the 'u' query parameter in ForgotPassUserName.php; alert on URL-encoded single quotes (%27) or boolean injection patterns in that parameter. ↗
• → The exploit requires a valid session cookie and is performed as an authenticated admin user; correlate suspicious ForgotPassUserName.php requests with active admin sessions. ↗

• · Exploitation requires an authenticated admin session; unauthenticated access to the vulnerable endpoint alone is insufficient to trigger the vulnerability. ↗
• · The vulnerability is confirmed only in openSIS Community Edition version 8.0; other versions are not explicitly confirmed as affected by this CVE. ↗
