CVE-2024-7115 Overview
CVE-2024-7115 is a SQL injection vulnerability in MD-MAFUJUL-HASAN Online-Payroll-Management-System through version 20230911. The flaw resides in /designation_viewmore.php, where the id parameter is passed directly into a SQL statement without sanitization [CWE-89]. Remote attackers with low privileges can manipulate the parameter to inject arbitrary SQL. The exploit has been publicly disclosed, and the project uses continuous delivery with rolling releases, so no fixed version is available. The vendor did not respond to disclosure attempts.
Critical Impact
Authenticated remote attackers can inject arbitrary SQL through the id parameter of designation_viewmore.php, exposing payroll data and enabling limited tampering of the underlying database.
Affected Products
- MD-MAFUJUL-HASAN Online-Payroll-Management-System up to 20230911
- Rolling releases published through the vendor repository (no fixed release available)
- Deployments exposing designation_viewmore.php to network-reachable users
Discovery Timeline
- 2024-07-26 - CVE-2024-7115 published to NVD
- 2026-06-17 - Last updated in NVD database
Technical Details for CVE-2024-7115
Vulnerability Analysis
The vulnerability is a classic SQL injection in the payroll application's designation-viewing page. The script /designation_viewmore.php accepts an id query parameter and concatenates it into a SQL query executed against the backend database. Because the parameter is neither validated nor bound as a prepared statement placeholder, an attacker can append SQL syntax to alter the query logic. Successful exploitation allows enumeration of database schema, extraction of stored payroll records, and manipulation of query results. According to the EPSS forecast dated 2026-08-25, the probability of exploitation is 0.542% at the 43.1 percentile.
Root Cause
The root cause is missing input validation and unsafe query construction in PHP code that processes the id request parameter. The application concatenates untrusted input directly into a SQL statement rather than using parameterized queries or prepared statements provided by PDO or MySQLi.
Attack Vector
An authenticated remote attacker sends a crafted HTTP request to /designation_viewmore.php with a malicious value in the id parameter. No user interaction is required. Because the product is delivered as a rolling release with no patched version, every deployment fetched from the upstream repository remains exposed. Public disclosure of the exploit lowers the barrier for opportunistic attacks against internet-facing installations.
The vulnerability manifests when the id query string parameter is embedded into a SQL statement without sanitization. Attackers typically append UNION-based or boolean-based payloads to the parameter to enumerate tables and columns, then extract sensitive payroll rows. Refer to the GitHub Security Collections write-up and the VulDB entry #272446 for the disclosed payload details.
Detection Methods for CVE-2024-7115
Indicators of Compromise
- Requests to /designation_viewmore.php containing SQL metacharacters such as ', ", --, UNION, SELECT, or SLEEP( in the id parameter.
- Web server access logs showing repeated requests to designation_viewmore.php with abnormally long or URL-encoded id values.
- Database error messages surfaced in HTTP responses indicating malformed SQL syntax.
- Unusual outbound queries from the payroll application's database user account outside normal application workflows.
Detection Strategies
- Deploy web application firewall (WAF) signatures for SQL injection targeting the id GET parameter of designation_viewmore.php.
- Enable database query logging and alert on queries referencing information_schema or UNION SELECT originating from the payroll application.
- Correlate authentication events with unusual query volume against the designation table to identify credential abuse combined with injection.
Monitoring Recommendations
- Forward web server and PHP error logs to a central analytics platform for pattern analysis.
- Baseline normal HTTP parameter lengths and character sets, then alert on statistical outliers against designation_viewmore.php.
- Monitor for exfiltration behavior such as large HTTP response bodies from a page that normally returns a single record.
How to Mitigate CVE-2024-7115
Immediate Actions Required
- Restrict network access to the Online-Payroll-Management-System deployment, placing it behind a VPN or IP allow list.
- Deploy WAF rules that block SQL injection payloads in the id parameter of /designation_viewmore.php and other endpoints.
- Rotate database credentials used by the application and verify that the account operates with the least privilege required.
- Review database and web server logs for prior exploitation attempts referencing designation_viewmore.php.
Patch Information
No official patch is available. The vendor uses continuous delivery with rolling releases and did not respond to disclosure. Operators should apply source-level fixes by converting affected queries to prepared statements with bound parameters, cast id to an integer before use, and validate all request parameters against an allow list. Track vendor updates via the project's upstream repository and the VulDB advisory.
Workarounds
- Modify designation_viewmore.php locally to cast the id parameter with intval() or use PDO::prepare with bound parameters.
- Add a reverse proxy rule that rejects requests to designation_viewmore.php where id is non-numeric.
- Disable the designation-view functionality until source-level remediation is verified in staging.
