CVE-2025-6910 Overview
CVE-2025-6910 is a SQL injection vulnerability in PHPGurukul Student Record System 3.2. The flaw resides in the /session.php file, where the session argument is passed to a database query without proper sanitization. Attackers can exploit this issue remotely by supplying crafted input that alters the SQL statement executed by the backend. The vendor advisory database VulDB tracks this issue under VulDB #314403, and a public disclosure exists in the GitHub Issue Discussion. The weakness maps to [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component).
Critical Impact
Remote authenticated attackers can manipulate SQL queries through the session parameter in /session.php, potentially exposing or modifying student record data.
Affected Products
- PHPGurukul Student Record System 3.2
- Deployments referencing the vulnerable /session.php endpoint
- Web applications built on the phpgurukul:student_record_system codebase

Technical Details for CVE-2025-6910
Vulnerability Analysis
The vulnerability affects the /session.php script in PHPGurukul Student Record System 3.2. The application accepts the session parameter from client requests and concatenates it into a SQL query without applying parameterized statements or input filtering. An attacker sends a manipulated session value to inject arbitrary SQL syntax, which the database engine then executes as part of the intended query.
The exploit has been disclosed publicly, lowering the barrier for opportunistic attackers to reproduce the attack against exposed installations. Because the affected endpoint handles session-related logic, successful injection can read or modify data available to the database user running the PHP process.
Root Cause
The root cause is improper neutralization of input passed to a downstream SQL interpreter, categorized under [CWE-74]. The session parameter reaches the query execution path without prepared statements or escaping. This defect allows attacker-controlled input to change the structure of the executed SQL statement.
Attack Vector
Exploitation occurs over the network against the HTTP interface of the vulnerable application. The attacker submits a request to /session.php containing a malicious session value. No advanced tooling is required, and knowledge of the exploit is public through third-party disclosure channels including VulDB CTI ID #314403.
The vulnerability is documented in public sources. See the GitHub Issue Discussion and PHP Gurukul Blog for context on the affected application.
Detection Methods for CVE-2025-6910
Indicators of Compromise
- HTTP requests to /session.php containing SQL metacharacters such as single quotes, UNION, SELECT, --, or OR 1=1 in the session parameter.
- Unexpected database errors or long-running queries originating from the Student Record System web process.
- Access patterns from a single source IP enumerating variations of the session parameter within a short time window.
Detection Strategies
- Deploy web application firewall rules that inspect the session parameter on /session.php for SQL injection payloads.
- Enable database query logging and alert on queries against the student records schema that contain tautologies or stacked statements.
- Correlate web server access logs with database audit logs to identify anomalous query structures tied to specific HTTP requests.
Monitoring Recommendations
- Baseline normal traffic patterns to /session.php and alert on deviations in request length or parameter entropy.
- Monitor for outbound data transfers from the database host that follow suspicious requests to the vulnerable endpoint.
- Track authentication failures and error responses from the application, which often accompany SQL injection probing.
How to Mitigate CVE-2025-6910
Immediate Actions Required
- Restrict network access to the Student Record System until a fix is applied, permitting only trusted administrative sources.
- Apply a virtual patch at the web application firewall to block SQL metacharacters in the session parameter of /session.php.
- Review database logs for evidence of exploitation attempts predating the mitigation.
Patch Information
No vendor advisory or official patch has been published for CVE-2025-6910 at the time of the referenced NVD entry. Consult the PHP Gurukul Blog for future updates from the vendor, and monitor VulDB Submit ID #605075 for tracking changes.
Workarounds
- Modify /session.php to use prepared statements with bound parameters instead of string concatenation for the session value.
- Enforce server-side input validation that constrains the session parameter to an expected character set and length.
- Run the database account used by the application with least privilege, removing rights to modify schema objects or read unrelated tables.
