CVE-2025-7927: PHPGurukul Banquet Booking SQL Injection

CVE-2025-7927 Overview

CVE-2025-7927 is a SQL injection vulnerability in PHPGurukul Online Banquet Booking System version 1.0. The flaw resides in /admin/view-user-queries.php where the viewid parameter is passed to a database query without proper sanitization. An authenticated remote attacker can manipulate this parameter to inject arbitrary SQL statements. The exploit details have 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).

Critical Impact
Authenticated attackers can extract, modify, or destroy administrative data stored in the banquet booking database through the vulnerable viewid parameter.

Technical Details for CVE-2025-7927

Vulnerability Analysis

The vulnerability exists in the administrative interface of the Online Banquet Booking System. The view-user-queries.php script accepts a viewid GET parameter intended to identify a specific user query record. The application concatenates this value directly into a SQL statement instead of using parameterized queries or input validation routines.

An attacker with administrative authentication can supply crafted SQL payloads through the viewid argument. Because the attack is remote and requires no user interaction beyond authentication, exploitation can be automated against exposed admin panels. Public disclosure of the exploit details, referenced in the GitHub Issue Report and VulDB #317056, lowers the technical barrier for attackers.

Root Cause

The root cause is the absence of prepared statements or input sanitization when handling the viewid parameter. PHP code paths in view-user-queries.php interpolate user-controlled input directly into MySQL queries. This pattern allows attackers to break out of the intended query context and append additional SQL clauses such as UNION SELECT or boolean-based blind injection vectors.

Attack Vector

The attack is delivered over the network against the administrative endpoint. An authenticated attacker sends an HTTP GET request to /admin/view-user-queries.php with a manipulated viewid value containing SQL syntax. The injected SQL is executed against the backend database, allowing data exfiltration, authentication table tampering, or destructive operations against booking records.

No verified proof-of-concept code is published in the NVD references; the vulnerability mechanism is documented in the linked VulDB and GitHub advisories.

Detection Methods for CVE-2025-7927

Indicators of Compromise

HTTP requests to /admin/view-user-queries.php containing SQL meta-characters such as single quotes, UNION, SELECT, --, or OR 1=1 in the viewid parameter.
Web server access logs showing repeated viewid requests with encoded payloads (%27, %20UNION%20).
Database error messages returned in HTTP responses, indicating malformed query execution.
Unusual outbound database connections or unexpected SELECT volume against the banquet booking schema.

Detection Strategies

Deploy a web application firewall rule that inspects the viewid parameter for SQL injection signatures and blocks anomalous values.
Enable database query logging and alert on queries originating from view-user-queries.php that include UNION, INFORMATION_SCHEMA, or stacked statements.
Review authentication logs to correlate admin sessions with suspicious request patterns against the admin directory.

Monitoring Recommendations

Forward web server and database logs to a central analytics platform for correlation across admin access and query patterns.
Establish baseline request volumes for /admin/view-user-queries.php and alert on deviations.
Monitor for new administrative accounts or modifications to existing privileged accounts that could indicate successful exploitation.

How to Mitigate CVE-2025-7927

Immediate Actions Required

Restrict network access to the /admin/ directory using IP allow-lists or VPN-only access until a patch is available.
Audit administrative account credentials and rotate passwords for all admin users.
Inspect web server logs for prior exploitation attempts against view-user-queries.php.
Place a web application firewall in front of the application to block SQL injection payloads targeting the viewid parameter.

Patch Information

No vendor patch is referenced in the NVD entry at the time of publication. Refer to the PHPGurukul website for vendor updates. Until an official fix is released, administrators should apply compensating controls or migrate to an alternative booking platform.

Workarounds

Modify the application source to replace string concatenation in view-user-queries.php with parameterized prepared statements using PHP mysqli or PDO.
Add server-side input validation that enforces a strict integer cast on the viewid parameter before any database call.
Disable or remove the view-user-queries.php endpoint if it is not required for daily operations.
Apply least-privilege principles to the database account used by the application to limit the blast radius of a successful injection.
