CVE-2025-6930 Overview
CVE-2025-6930 is a SQL injection vulnerability in PHPGurukul Zoo Management System 2.1. The flaw resides in the /admin/manage-foreigners-ticket.php script, where the ID parameter is passed unsanitized into a backend SQL query. An authenticated remote attacker can manipulate the parameter to alter query logic, read database contents, or modify records. The exploit details have been publicly disclosed, increasing the likelihood of opportunistic exploitation against exposed installations. The vulnerability maps to CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component.
Critical Impact
Authenticated attackers can inject arbitrary SQL into the ID parameter of /admin/manage-foreigners-ticket.php, exposing or modifying zoo ticket records and administrative data.
Affected Products
- PHPGurukul Zoo Management System 2.1
- Deployments using the /admin/manage-foreigners-ticket.php administrative endpoint
- Web applications sharing the PHPGurukul codebase patterns for ticket management

Technical Details for CVE-2025-6930
Vulnerability Analysis
The vulnerability stems from improper handling of the ID request parameter inside /admin/manage-foreigners-ticket.php. The script concatenates user-supplied input directly into a SQL statement without parameterization or input validation. An attacker authenticated to the admin interface can append SQL syntax to the parameter and influence the resulting query execution.
Successful exploitation allows the attacker to enumerate database tables, extract foreigner ticket records, and tamper with administrative data. Because the attack vector is network-based and the public proof-of-concept guidance is available through the referenced GitHub issue and VulDB entry, exploitation barriers are low for any attacker with admin credentials.
The EPSS probability of 0.318% indicates limited near-term mass exploitation expectations, though targeted attacks against exposed instances remain viable.
Root Cause
The root cause is the absence of prepared statements or input sanitization on the ID GET parameter. The application trusts the incoming value and interpolates it into a raw SQL string, allowing SQL metacharacters such as single quotes, UNION, and comment sequences to break query structure.
Attack Vector
The attacker authenticates to the administrative panel, then issues a crafted HTTP request to /admin/manage-foreigners-ticket.php with a malicious ID value. Payloads typically include UNION SELECT statements to exfiltrate data or boolean conditions to enumerate schema details. No user interaction beyond the authenticated session is required.
The vulnerability is described in publicly available technical references. See the VulDB advisory and PHPGurukul project page for additional context.
Detection Methods for CVE-2025-6930
Indicators of Compromise
- HTTP requests to /admin/manage-foreigners-ticket.php containing SQL metacharacters in the ID parameter, such as ', --, UNION, SELECT, or SLEEP(
- Unusual database error messages appearing in PHP application logs referencing the foreigners ticket table
- Unexpected outbound database query volume originating from the admin endpoint
- Newly created or modified administrative accounts in the Zoo Management System database
Detection Strategies
- Deploy web application firewall rules that match SQL injection signatures against requests targeting /admin/manage-foreigners-ticket.php
- Enable MySQL general query logging to capture syntactically anomalous queries against the foreigners ticket table
- Correlate admin authentication events with subsequent parameter tampering on the ID field
Monitoring Recommendations
- Forward Apache or Nginx access logs to a centralized logging platform and alert on URI patterns containing encoded SQL keywords
- Monitor admin session activity for repeated requests with varying ID parameter payloads, which indicates enumeration attempts
- Track database error rates and alert on spikes correlated with HTTP 200 responses on the affected endpoint
How to Mitigate CVE-2025-6930
Immediate Actions Required
- Restrict access to /admin/ paths to trusted IP ranges using web server access controls
- Rotate all administrative credentials and review admin account inventory for unauthorized additions
- Audit the tbl_foreigners_ticket table and related records for unauthorized modifications
- Place a web application firewall in front of the application with SQL injection rule sets enabled
Patch Information
No official vendor patch is referenced in the NVD entry for CVE-2025-6930. Operators should consult the PHPGurukul project site for vendor updates and review the public disclosure on GitHub for technical remediation context. Until a patch is published, apply the workarounds below.
Workarounds
- Modify /admin/manage-foreigners-ticket.php to cast the ID parameter to an integer before use in any SQL statement
- Replace string concatenation with PDO prepared statements or mysqli_prepare parameter binding
- Disable the affected administrative endpoint if foreigner ticket management is not actively used
- Apply server-side input validation that rejects any non-numeric value for the ID parameter
# Example Apache configuration to restrict admin path access
<Location "/admin/manage-foreigners-ticket.php">
Require ip 10.0.0.0/8
Require ip 192.168.0.0/16
</Location>
# Example ModSecurity rule to block SQLi patterns on the ID parameter
SecRule ARGS:ID "@detectSQLi" \
"id:1006930,phase:2,deny,status:403,\
msg:'CVE-2025-6930 SQLi attempt on manage-foreigners-ticket.php'"
