CVE Alert: CVE-2025-12242 – CodeAstro – Gym Management System

Risk verdict

Medium risk; remote SQL injection with publicly available PoC; patch promptly recommended.

Why this matters

The flaw allows an attacker to read or modify data from the application’s database without authentication, potentially exposing personal information and undermining attendance integrity. Depending on the stored data, this can affect regulatory compliance, reporting accuracy, and trust in the system; exploitation could disrupt day-to-day operations for a gym or chain.

Most likely attack path

• Exploitation is network-based with no user interaction and low credentials required (AV:N, AC:L, PR:L, UI:N, S:U).
• An attacker supplies a crafted ID to /admin/actions/check-attendance.php, taking advantage of a vulnerable SQL query to exfiltrate or modify data.
• Given scope is unchanged, the impact is limited to the application’s database, but compromise of attendance data can enable broader data exposure if the DB houses additional records.

Who is most exposed

Typically, small-to-medium gym management deployments with internet-facing admin interfaces or default hosting configurations are most at risk; sites using on-prem or lightweight hosting without strict access controls are common patterns.

Detection ideas

• Look for suspicious input in ID parameters hitting check-attendance.php (unexpected length/special chars).
• SQL error messages or abnormal database error traces in app logs.
• WAF alerts or IDS signatures targeting SQLi patterns on the attendance endpoint.
• Sudden spikes or unusual access from external IPs to the admin path.
• PoC-like payloads observed in traffic or logs (e.g., attempts containing 1=1, UNION SELECT).

Mitigation and prioritisation

• Apply patch or upgrade to the fixed release; confirm versioned remediation.
• Convert the vulnerable code to parameterised queries/prepared statements; implement input validation.
• Apply least-privilege DB accounts and restrict the admin endpoint behind VPN or IP allow-lists.
• Implement or tune a WAF with SQL injection rules for the attendance API; monitor for repeated attempts.
• Establish change-management testing in a staging environment before production rollout.
