CVE Alert: CVE-2025-10100 – SourceCodester – Simple Forum Discussion System

Risk verdict

Remote, unauthenticated SQL injection targeting the admin login, with a public PoC and exploit available; urgent remediation is required.

Why this matters

Successful exploitation could grant attacker access to the admin panel, enabling data exfiltration, modification or destruction and potential long-term compromise of the forum environment. With no user interaction and automated exploitation possible, exposed deployments are at high risk of rapid compromise.

Most likely attack path

An attacker submits a crafted Username value to /admin_class.php?action=login, triggering SQL injection without credentials. The attacker can read or modify data and may achieve elevated access within the app; the attack relies on weak input handling rather than privileged execution, and could enable limited but impactful persistence or data exposure within the same security domain.

Who is most exposed

Typical targets are small-to-midsize web apps running PHP/MySQL with publicly accessible admin endpoints, especially on shared hosting or legacy installations lacking input sanitisation.

Detection ideas

• Web logs show login requests with suspicious SQL syntax in Username (quotes, UNION, SELECT).
• Increased database errors or stack traces linked to the admin login endpoint.
• Sudden spikes in failed login attempts or unusual admin-login activity.
• WAF/IDS alerts for SQLi patterns on admin_class.php.
• PoC indicators or known payload signatures in traffic or code paths.

Mitigation and prioritisation

• Apply vendor patch or upgrade to fixed version; if unavailable, implement parameterised queries and strict input validation in the login flow.
• Implement immediate compensating controls: web application firewall rules targeting SQLi on the admin endpoint, rate limiting, and least-privilege DB accounts.
• Review and harden logging and error handling; disable verbose DB errors from user-visible responses.
• Change management: deploy in staging first, then production with verification; monitor for anomalous admin activity.
• If KEV true or EPSS ≥ 0.5 becomes confirmed, treat as priority 1. Otherwise, treat as high-priority due to PoC/public exploit.
