CVE-2025-13243 Overview
CVE-2025-13243 is a SQL injection vulnerability in code-projects Student Information System 2.0. The flaw resides in an unspecified function within the /editprofile.php script. Attackers can manipulate input parameters to inject arbitrary SQL statements into backend database queries. The vulnerability is remotely exploitable and a public exploit description has been disclosed. The issue is tracked under [CWE-89] (SQL Injection) and [CWE-74] (Improper Neutralization of Special Elements in Output).
Critical Impact
Authenticated remote attackers can inject SQL through /editprofile.php, potentially reading or modifying records in the underlying database used by the Student Information System.
Affected Products
- Fabian Student Information System 2.0
- Component: fabian:student_information_system
- Vulnerable endpoint: /editprofile.php

Technical Details for CVE-2025-13243
Vulnerability Analysis
The vulnerability exists in the /editprofile.php script of the Student Information System 2.0. User-supplied input is concatenated into a SQL statement without proper sanitization or parameterization. An attacker with low-privilege authenticated access can submit crafted profile-edit parameters to alter the resulting query. The issue maps to [CWE-89], reflecting failure to neutralize special SQL syntax in untrusted input. Public disclosure of the exploit technique is referenced through the GitHub CVE SQL Injection Guide and VulDB entry #332569.
Root Cause
The root cause is improper neutralization of special characters within SQL statements built inside /editprofile.php. The application appears to concatenate request parameters directly into database queries instead of using prepared statements or bind variables. This pattern allows attacker-controlled values such as quotes, comments, and union operators to break out of the intended query context.
Attack Vector
Exploitation occurs over the network against a running instance of the Student Information System. The attacker authenticates with low-privilege credentials, then submits crafted POST or GET parameters to the profile-edit endpoint. Successful injection can yield record disclosure, modification of profile or grade data, or authentication-related tampering, depending on the underlying query and database privileges.
No verified proof-of-concept code is included in this advisory. For technical specifics, refer to the VulDB CTI entry #332569 and the GitHub SQL Injection write-up.
Detection Methods for CVE-2025-13243
Indicators of Compromise
- HTTP requests to /editprofile.php containing SQL meta-characters such as single quotes, --, UNION SELECT, OR 1=1, or hex-encoded payloads.
- Database error messages or unusual response sizes returned from /editprofile.php.
- Unexpected modifications to student profile, account, or related records in the application database.
Detection Strategies
- Inspect web server access logs for repeated requests to /editprofile.php with anomalous query strings or POST bodies.
- Deploy a web application firewall (WAF) rule set targeting SQL injection patterns on the profile-edit endpoint.
- Enable database query logging and alert on syntactically unusual statements originating from the application user.
Monitoring Recommendations
- Correlate authenticated session activity with /editprofile.php traffic to detect a single account issuing injection-style payloads.
- Monitor for outbound data spikes or large result sets returned by the application database immediately after profile-edit requests.
- Track schema reconnaissance queries against information_schema tables initiated from the application's database account.
How to Mitigate CVE-2025-13243
Immediate Actions Required
- Restrict network access to the Student Information System to trusted users until the application is patched or replaced.
- Audit and rotate database credentials used by the application, and ensure the account holds only the minimum privileges needed.
- Review recent activity on /editprofile.php for evidence of exploitation prior to publication of this advisory.
Patch Information
At the time of publication, no vendor advisory or official patch has been published for code-projects Student Information System 2.0. Consult the code-projects website for updates and consider migrating to a maintained alternative if no fix is released.
Workarounds
- Place the application behind a WAF configured to block SQL injection payloads targeting /editprofile.php.
- Implement server-side input validation and parameterized queries in any local fork of the source code before redeploying.
- Disable or restrict the profile-edit functionality if it is not required for business operations.
