CVE-2025-7600 Overview
CVE-2025-7600 is a SQL injection vulnerability in PHPGurukul Online Library Management System 3.0. The flaw resides in /admin/student-history.php, where the stdid parameter is passed to a database query without sanitization. An authenticated attacker with low privileges can manipulate the parameter to inject arbitrary SQL statements. The exploit has been publicly disclosed, increasing the likelihood of opportunistic attacks against exposed installations. The vulnerability is classified under CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component. It can be triggered remotely over the network without user interaction.
Critical Impact
Authenticated attackers can extract, modify, or delete records in the library database by injecting SQL through the stdid parameter in the admin student history endpoint.
Affected Products
- PHPGurukul Online Library Management System 3.0
- Installations exposing /admin/student-history.php to network-reachable attackers
- Deployments using the unpatched vendor distribution from PHPGurukul

Technical Details for CVE-2025-7600
Vulnerability Analysis
The vulnerability affects the administrative student history page in PHPGurukul Online Library Management System 3.0. The stdid parameter received by /admin/student-history.php is concatenated directly into a SQL query string. Because the application does not validate, sanitize, or parameterize this input, an attacker can append SQL syntax that the database executes as part of the original statement.
Exploitation requires an authenticated session with administrative access, but the attack itself can be carried out remotely over HTTP. Successful injection allows the attacker to read arbitrary tables, including borrower records, staff credentials, and book inventory. Depending on database privileges, attackers can also modify or delete records and stage further attacks against the underlying server.
Root Cause
The root cause is the use of unsanitized user input within a dynamically constructed SQL query. The application fails to apply prepared statements or input validation to the stdid GET/POST parameter. This pattern, classified under CWE-74, is a recurring weakness across multiple PHPGurukul applications.
Attack Vector
An attacker authenticates to the administrative interface, then issues a crafted request to /admin/student-history.php with a malicious stdid value. Typical payloads include UNION-based queries to enumerate schema content or boolean and time-based payloads to extract data blindly. No user interaction is required beyond the attacker's own request. Refer to the GitHub Issue Report and VulDB entry #316299 for technical observations from the disclosure.
Detection Methods for CVE-2025-7600
Indicators of Compromise
- HTTP requests to /admin/student-history.php containing SQL meta-characters such as single quotes, UNION SELECT, SLEEP(, or -- in the stdid parameter
- Database error messages referencing stdid or student-history.php in application or web server logs
- Unexpected outbound queries from the database service triggered by injected INTO OUTFILE or similar payloads
Detection Strategies
- Inspect web server access logs for anomalous query strings on the student-history.php endpoint, particularly long or URL-encoded stdid values
- Deploy a web application firewall ruleset that flags SQL injection signatures targeting administrative PHP endpoints
- Correlate authenticated admin session activity with database error rates to identify probing behavior
Monitoring Recommendations
- Enable verbose query logging on the MySQL or MariaDB backend to capture syntactically anomalous statements originating from the web application
- Alert on repeated 500-class responses from /admin/student-history.php, which often indicate failed injection attempts
- Track administrative authentication events and flag sessions that generate atypical volumes of requests against student history resources
How to Mitigate CVE-2025-7600
Immediate Actions Required
- Restrict network access to the /admin/ directory using IP allow-listing or VPN-only access until a fix is applied
- Rotate administrative credentials and review accounts that may have been used to exploit the endpoint
- Audit the library database for unauthorized record changes or new accounts created through injection
Patch Information
No vendor patch is listed in the NVD entry or referenced advisories at the time of publication. Monitor the PHPGurukul website for updates to the Online Library Management System. Until an official patch is released, apply the workarounds below and consider migrating to a supported library management platform.
Workarounds
- Modify /admin/student-history.php to use parameterized queries via PDO or mysqli_prepare instead of string concatenation
- Cast stdid to an integer at the start of the script ($stdid = (int)$_GET['stdid'];) to neutralize string-based injection payloads
- Deploy a WAF rule that blocks requests where the stdid parameter contains non-numeric characters
- Disable or remove the student history administrative page if it is not required for operations
# Example ModSecurity rule to block non-numeric stdid values
SecRule REQUEST_URI "@contains /admin/student-history.php" \
"chain,phase:2,deny,status:403,id:1007600,\
msg:'CVE-2025-7600 SQLi attempt against student-history.php'"
SecRule ARGS:stdid "!@rx ^[0-9]+$" "t:none"
