CVE-2025-10483 Overview
CVE-2025-10483 is a SQL injection vulnerability in SourceCodester Online Student File Management System 1.0, developed by Janobe. The flaw resides in the /admin/save_user.php script, where the firstname parameter is passed to a database query without proper sanitization. An authenticated remote attacker can manipulate this parameter to inject arbitrary SQL statements. Other parameters in the same endpoint may also be affected. The exploit has been publicly disclosed, increasing the likelihood of opportunistic abuse against exposed installations.
Critical Impact
Authenticated attackers can inject SQL commands through the firstname parameter in /admin/save_user.php, potentially exposing or modifying records in the underlying database.

Technical Details for CVE-2025-10483
Vulnerability Analysis
The vulnerability is classified under [CWE-89] Improper Neutralization of Special Elements used in an SQL Command and [CWE-74] Improper Neutralization of Special Elements in Output Used by a Downstream Component. The affected endpoint /admin/save_user.php accepts user input through the firstname POST parameter and concatenates it directly into a SQL statement. Because the input is neither parameterized nor escaped, attacker-controlled payloads alter the structure of the executed query. Successful exploitation allows reading, modifying, or deleting records that the database account can access. The advisory notes that additional parameters in the same request may exhibit the same flaw.
Root Cause
The root cause is the absence of prepared statements or input validation in the user-save handler. PHP code in save_user.php builds SQL queries through string concatenation, so any quote-breaking payload reaches the database engine intact. This pattern is recurring across SourceCodester-distributed PHP applications that lack a data-access abstraction layer.
Attack Vector
Exploitation requires network access to the admin interface and a valid low-privilege session, as indicated by the PR:L component in the CVSS vector. An attacker submits a crafted POST request to /admin/save_user.php containing SQL metacharacters in firstname. The injected payload executes within the context of the application's database user. Public proof-of-concept information is available through the GitHub CVE Issue Discussion and the VulDB Entry #323918.
No verified exploit code is reproduced here. Refer to the linked advisory entries for technical artifacts.
Detection Methods for CVE-2025-10483
Indicators of Compromise
- POST requests to /admin/save_user.php containing SQL metacharacters such as single quotes, UNION, SLEEP(, or comment sequences -- and # in the firstname field.
- Web server access logs showing repeated 200 or 500 responses from save_user.php originating from a single source IP.
- Database error messages referencing syntax errors triggered by user creation workflows.
Detection Strategies
- Deploy web application firewall rules that inspect POST parameters submitted to /admin/save_user.php for SQL injection signatures.
- Enable database query logging and alert on anomalous queries originating from the application service account, especially queries containing INFORMATION_SCHEMA references.
- Correlate authentication events with subsequent administrative endpoint activity to identify low-privilege accounts probing user-management functionality.
Monitoring Recommendations
- Monitor outbound database traffic for unusually large result sets returned to the web tier following requests to user-management endpoints.
- Track failed administrative login attempts followed by successful authentication, which may indicate credential reuse preceding exploitation.
- Review application error logs for stack traces emitted by save_user.php referencing MySQL or MariaDB driver errors.
How to Mitigate CVE-2025-10483
Immediate Actions Required
- Restrict network access to the /admin/ directory using IP allowlisting or VPN-gated access until a patch is available.
- Rotate credentials for all administrative accounts on affected deployments and review the user table for unauthorized entries.
- Audit the underlying database for unexpected schema changes, new privileged accounts, or data exfiltration artifacts.
Patch Information
No official vendor patch has been published for Janobe Online Student File Management System 1.0 at the time of NVD publication. Operators should track updates through the SourceCodester Security Resource and the VulDB CTI Entry #323918 for remediation guidance.
Workarounds
- Replace the vulnerable query in save_user.php with a parameterized statement using PDO or mysqli_prepare to bind the firstname value safely.
- Apply input validation that rejects non-alphabetic characters in name fields before the data reaches the database layer.
- Deploy a reverse proxy or WAF with signature-based SQL injection rules covering the /admin/save_user.php path.
# Example WAF rule (ModSecurity) blocking SQL metacharacters in firstname
SecRule REQUEST_URI "@streq /admin/save_user.php" \
"phase:2,chain,deny,status:403,id:1010483,msg:'CVE-2025-10483 SQLi attempt'"
SecRule ARGS:firstname "@rx (?i)(\b(union|select|sleep|benchmark)\b|--|#|')" \
"t:none,t:urlDecode"
