CVE-2025-6929: Zoo Management System SQL Injection Flaw

CVE-2025-6929 Overview

CVE-2025-6929 is a SQL injection vulnerability in PHPGurukul Zoo Management System 2.1. The flaw exists in the /admin/view-normal-ticket.php script, where the viewid parameter is passed to a database query without proper sanitization [CWE-74]. An authenticated attacker can manipulate the viewid argument to inject arbitrary SQL statements. The attack can be initiated remotely over the network, and the exploit has been publicly disclosed.

Critical Impact
Remote attackers with low-level privileges can manipulate backend SQL queries through the viewid parameter, potentially exposing or altering data within the Zoo Management System database.

Technical Details for CVE-2025-6929

Vulnerability Analysis

The vulnerability resides in the administrative ticket-viewing functionality of PHPGurukul Zoo Management System 2.1. The view-normal-ticket.php script accepts a viewid parameter via HTTP request and concatenates the value directly into a backend SQL statement. Because the application does not validate or parameterize the input, an attacker can append SQL syntax to alter the query logic.

The flaw is classified under [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component). Exploitation is performed remotely and requires low-privilege authentication to the administrative interface. The public disclosure of the exploit increases the likelihood of opportunistic abuse against exposed instances.

Root Cause

The root cause is the absence of prepared statements or input sanitization on the viewid parameter inside /admin/view-normal-ticket.php. User-supplied data flows directly into a dynamically constructed SQL query, enabling syntax manipulation.

Attack Vector

An authenticated attacker sends a crafted HTTP request to the vulnerable admin endpoint with a malicious payload in the viewid query parameter. The injected SQL is executed by the underlying database, allowing the attacker to read, modify, or extract data. No user interaction is required beyond the attacker's own request.

No verified proof-of-concept code is published for inclusion here. Refer to the GitHub Issue on CVE and VulDB #314441 for technical details.

Detection Methods for CVE-2025-6929

Indicators of Compromise

HTTP requests to /admin/view-normal-ticket.php containing SQL metacharacters such as single quotes, UNION, SELECT, --, or OR 1=1 in the viewid parameter.
Unusual database error messages logged by the PHP application referencing the viewid query.
Anomalous administrative session activity originating from unexpected IP addresses.

Detection Strategies

Inspect web server access logs for non-numeric or encoded values supplied to the viewid parameter.
Deploy a web application firewall (WAF) rule set to flag SQL injection patterns targeting the admin path.
Monitor database query logs for unexpected statements originating from the view-normal-ticket.php execution context.

Monitoring Recommendations

Enable verbose logging on the MySQL/MariaDB backend to capture full statements during the investigation window.
Alert on repeated 500-series HTTP responses from /admin/view-normal-ticket.php, which often indicate injection probing.
Correlate authentication events with subsequent admin endpoint access to identify abuse of compromised credentials.

How to Mitigate CVE-2025-6929

Immediate Actions Required

Restrict access to the /admin/ directory using IP allowlists or network-level access controls.
Rotate administrative credentials and enforce strong password policies on all admin accounts.
Audit recent access logs for the affected endpoint to identify potential exploitation attempts.

Patch Information

No vendor patch is referenced in the available advisory data for PHPGurukul Zoo Management System 2.1. Operators should monitor the PHPGurukul website for updated releases and consult VulDB CTI ID #314441 for remediation status.

Workarounds

Implement server-side input validation to ensure the viewid parameter accepts only numeric values.
Place the application behind a WAF configured with OWASP Core Rule Set protections against SQL injection.
Disable or remove the affected administrative endpoint until a vendor fix is available.
