CVE-2024-7276 Overview
CVE-2024-7276 is a SQL injection vulnerability in itsourcecode Alton Management System 1.0. The flaw resides in the /admin/member_save.php script, where the last and first parameters are passed directly into a SQL query without proper sanitization. Remote attackers with authenticated administrative access can manipulate these parameters to inject arbitrary SQL statements. The exploit details have been publicly disclosed under identifier VDB-273145, increasing the likelihood of opportunistic exploitation against exposed installations.
Critical Impact
Successful exploitation allows attackers to read, modify, or delete database records, including credentials and member data stored by the Alton Management System.

Technical Details for CVE-2024-7276
Vulnerability Analysis
The vulnerability is classified under [CWE-89] Improper Neutralization of Special Elements used in an SQL Command. The member_save.php administrative script accepts user-controlled last and first input fields, which are concatenated into a SQL statement without parameterization or input escaping. An authenticated attacker with administrative privileges can submit crafted values that break out of the intended query context. This allows execution of arbitrary SQL against the backing database, enabling data extraction, manipulation, and potential authentication bypass on related tables. The EPSS score of 0.596% reflects moderate near-term exploitation probability, aligned with the public disclosure of proof-of-concept material on GitHub and VulDB.
Root Cause
The root cause is the direct inclusion of untrusted HTTP request parameters into a dynamically constructed SQL query. The application does not use prepared statements or parameterized queries and fails to sanitize input received from the member management form.
Attack Vector
The attack is remote and network-accessible. An attacker sends a crafted HTTP request to /admin/member_save.php with malicious payloads in the last or first parameters. Because the attack requires high privileges, exploitation typically follows credential compromise, insider misuse, or chaining with authentication weaknesses.
No verified proof-of-concept code is available for direct inclusion. Technical details are documented in the GitHub CVE Documentation and VulDB entry #273145.
Detection Methods for CVE-2024-7276
Indicators of Compromise
- HTTP POST requests to /admin/member_save.php containing SQL metacharacters such as single quotes, UNION, SELECT, --, or /* in the last or first parameters.
- Unexpected database errors or 500-level responses generated by the Alton Management System web tier.
- Anomalous administrative sessions creating or modifying member records outside normal business hours.
Detection Strategies
- Deploy web application firewall signatures targeting SQL injection payloads directed at member_save.php.
- Enable database query logging and alert on syntactically abnormal queries originating from the application service account.
- Correlate authenticated admin logins with subsequent parameter tampering behavior in access logs.
Monitoring Recommendations
- Monitor administrative endpoints for high-frequency parameter mutation typical of automated SQLi tooling such as sqlmap.
- Track outbound data volumes from the database host to detect exfiltration following successful injection.
- Alert on new or modified admin accounts within the Alton Management System user table.
How to Mitigate CVE-2024-7276
Immediate Actions Required
- Restrict access to /admin/ paths using IP allowlists or VPN-only reachability until a patched build is available.
- Rotate all administrative credentials for the Alton Management System and enforce multi-factor authentication at the reverse proxy layer.
- Audit the members and related tables for unauthorized inserts, updates, or deletions.
Patch Information
No vendor patch has been published in the referenced advisories. Operators should track the VulDB CTI record and the vendor's distribution channels for updates. Where feasible, replace the vulnerable member_save.php handler with a version that uses parameterized queries via PDO or mysqli_prepare.
Workarounds
- Apply a WAF rule blocking SQL metacharacters in last and first POST parameters on /admin/member_save.php.
- Refactor the affected script locally to use prepared statements with bound parameters before returning the application to production use.
- Remove the Alton Management System from public-facing networks if it is not actively required.
