CVE Alert: CVE-2025-12326 – shawon100 – RUET OJ

Risk verdict

Urgent: publicly available PoC enables unauthenticated, remote SQL injection; exploitation is highly feasible.

Why this matters

Remote, unauthenticated access means an attacker can enumerate or exfiltrate data from the backend database, modify records, or escalate within the app environment if DB permissions permit. The exploit is publicly disclosed, increasing likelihood of automated scanning and weaponisation against internet-facing deployments.

Most likely attack path

An attacker sends a crafted POST request to the vulnerable endpoint, injecting via the un parameter to trigger SQL injection. With AV:N, AC:L, PR:N, UI:N, the barrier is low and no user interaction is required; success can yield data or corrupt data stores, potentially enabling further access depending on database privileges.

Who is most exposed

Web-facing deployments with unauthenticated POST handlers are at highest risk, especially where input validation is weak, logs or error messages expose SQL details, or database accounts lack proper least-privilege controls.

Detection ideas

• Spike in POST traffic to the endpoint with suspicious payloads.
• SQL error messages or unusually slow responses tied to the endpoint.
• DB query latency rises or error logs indicating syntax issues.
• WAF/IDS alerts for SQLi-like patterns.
• Unexpected data dumps or exfiltration indicators.

Mitigation and prioritisation

• Implement parameterised queries and prepared statements; validate and scrub inputs.
• Enforce least-privilege DB accounts; restrict database permissions.
• Suppress verbose error messages; standardise safe error handling.
• Deploy or tune a Web Application Firewall with SQLi rules; monitor alerts.
• Apply available patches or upgrade to fixed versions; plan remediation within the next maintenance window.
