CVE-2025-5838: PHPGurukul Employee Record SQLI Flaw

CVE-2025-5838 Overview

CVE-2025-5838 is a SQL injection vulnerability in PHPGurukul Employee Record Management System version 1.3. The flaw resides in the /admin/adminprofile.php script, where the AdminName parameter is passed into a database query without proper sanitization. Authenticated attackers can manipulate this parameter remotely to inject arbitrary SQL statements. The exploit has been publicly disclosed, increasing the likelihood of opportunistic attacks against exposed deployments. The weakness is categorized under [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component).

Critical Impact
Attackers with low-privilege admin access can extract, modify, or delete database records through SQL injection against the AdminName parameter in /admin/adminprofile.php.

Affected Products

PHPGurukul Employee Record Management System 1.3
Deployments using the bundled /admin/adminprofile.php administrative module
Any forks or derivative installations that retain the vulnerable query logic

Technical Details for CVE-2025-5838

Vulnerability Analysis

The vulnerability exists in the administrative profile handler /admin/adminprofile.php. The AdminName request parameter flows directly into a SQL statement without parameterized queries or input validation. An authenticated attacker submits crafted SQL syntax through this parameter to alter query logic. Successful exploitation can disclose administrator credentials, modify employee records, or pivot toward broader database manipulation.

The attack requires network reachability to the admin interface and a low-privilege session. Public disclosure on the GitHub Issue Discussion provides reproduction details. The EPSS probability is 0.318% with a percentile of 23.37, indicating limited but non-zero predicted exploitation activity.

Root Cause

The application concatenates the AdminName value into a dynamic SQL query string. PHPGurukul Employee Record Management System 1.3 does not use prepared statements or apply server-side sanitization on this parameter. This direct string interpolation creates the injection primitive.

Attack Vector

The attacker authenticates to the admin panel and sends an HTTP request to /admin/adminprofile.php containing SQL metacharacters in the AdminName field. Payloads using UNION SELECT, boolean-based blind techniques, or stacked queries can return sensitive data or alter records. Because the attack is network-based and remotely launchable, internet-exposed deployments face the highest risk. Refer to the VulDB #311581 entry for additional technical context.

Detection Methods for CVE-2025-5838

Indicators of Compromise

HTTP POST or GET requests to /admin/adminprofile.php containing SQL keywords such as UNION, SELECT, SLEEP(, or -- within the AdminName parameter
Unexpected administrator accounts or modified records in the admin table
Web server logs showing repeated 500 errors or anomalous response sizes from adminprofile.php
Outbound database connections or queries originating from the admin profile endpoint at unusual hours

Detection Strategies

Deploy web application firewall rules that inspect the AdminName parameter for SQL syntax tokens and known injection signatures
Enable database query logging and alert on dynamic queries referencing adminprofile.php that contain OR 1=1, comment sequences, or sub-selects
Correlate authenticated admin sessions against query anomalies to identify low-and-slow blind injection attempts

Monitoring Recommendations

Forward web server access logs and MySQL general query logs to a centralized analytics platform for correlation
Baseline normal AdminName values and flag requests containing non-alphanumeric characters
Monitor admin authentication events for credential brute-force activity that often precedes injection attacks

How to Mitigate CVE-2025-5838

Immediate Actions Required

Restrict access to /admin/ endpoints using IP allowlists, VPN, or reverse proxy authentication until a patch is applied
Rotate all administrator credentials and database service account passwords stored within the application
Audit the admin and employee tables for unauthorized modifications introduced through the vulnerable parameter

Patch Information

No vendor patch is currently referenced in the NVD entry or the linked PHP Gurukul Resource. Operators should monitor the vendor site and the VulDB CTI ID #311581 advisory for fix availability. Until an official patch is released, apply the workarounds below.

Workarounds

Modify /admin/adminprofile.php to use prepared statements with parameter binding (mysqli_prepare or PDO) for any query referencing AdminName
Apply server-side input validation that rejects non-alphanumeric characters in the AdminName parameter
Deploy a web application firewall with OWASP CRS rules enabled to block common SQL injection payloads targeting administrative endpoints
Remove or disable the admin profile module if it is not required for daily operations

bash

# Example ModSecurity rule to block SQLi attempts against AdminName
