CVE-2024-5359: Zoo Management System SQLi Vulnerability

CVE-2024-5359 Overview

CVE-2024-5359 is a SQL injection vulnerability in PHPGurukul Zoo Management System 2.1. The flaw resides in the /admin/foreigner-search.php script, where the searchdata parameter is passed into a database query without proper sanitization. Remote attackers with low-privileged access can manipulate the parameter to inject arbitrary SQL statements. The vulnerability is tracked under VulDB identifier VDB-266271 and has been publicly disclosed. The weakness maps to [CWE-89] Improper Neutralization of Special Elements used in an SQL Command.

Critical Impact

Authenticated remote attackers can inject SQL through the searchdata parameter in /admin/foreigner-search.php, exposing administrative database contents.

Affected Products

Technical Details for CVE-2024-5359

Vulnerability Analysis

The vulnerability exists in the foreigner search functionality of the administrator panel. The searchdata POST parameter is concatenated directly into a SQL statement executed against the application database. Because the application does not validate or parameterize the input, an attacker can break out of the intended query context. Exploitation requires network access to the admin interface and a low-privileged authenticated session.

Successful injection allows extraction of arbitrary table contents, including administrator credentials and visitor records. Attackers can also leverage stacked queries or UNION-based payloads to enumerate the database schema. Because the exploit has been disclosed publicly via VulDB, opportunistic scanning against exposed PHPGurukul installations is plausible.

Root Cause

The root cause is the use of unsanitized user input in dynamic SQL query construction. The searchdata value reaches the database layer without prepared statements, type casting, or input validation. PHP applications that rely on direct concatenation with mysqli_query or similar APIs are prone to this class of defect. The fix requires parameterized queries or strict allowlist validation of search input.

Attack Vector

The attack is performed remotely over HTTP against the /admin/foreigner-search.php endpoint. An attacker submits a crafted searchdata value containing SQL meta-characters such as single quotes, comment markers, or UNION SELECT clauses. The application returns results derived from the injected query, enabling boolean-based, error-based, or union-based extraction techniques. No user interaction beyond the attacker's own request is required.

No verified proof-of-concept code is available in trusted repositories. Technical details are referenced in the VulDB entry #266271 and an associated Yuque security writeup.

Detection Methods for CVE-2024-5359

Indicators of Compromise

• HTTP POST requests to /admin/foreigner-search.php containing SQL meta-characters such as ', --, UNION, or SLEEP( in the searchdata field.
• Web server access logs showing repeated requests to the foreigner search endpoint from a single source within a short time window.
• Unexpected database errors logged by the PHP application referencing the foreigner table or related queries.
• New or modified administrative accounts in the Zoo Management System database following suspicious search activity.

Detection Strategies

• Deploy web application firewall (WAF) signatures targeting SQL injection patterns on the searchdata parameter.
• Enable verbose database query logging and alert on syntactically anomalous queries against the foreigner table.
• Compare baseline traffic profiles to flag enumeration patterns such as long-running boolean-based requests.

Monitoring Recommendations

• Forward Apache or Nginx access logs to a centralized SIEM and create rules for SQL injection payloads on PHPGurukul endpoints.
• Monitor outbound database connections from the web tier for unexpected INFORMATION_SCHEMA queries.
• Audit administrator authentication events for unusual session origins after detected probing activity.

How to Mitigate CVE-2024-5359

Immediate Actions Required

• Restrict network access to the /admin/ directory using IP allowlists or VPN-only access until a patch is available.
• Rotate all administrator credentials stored in the Zoo Management System database.
• Deploy WAF rules that block SQL meta-characters in the searchdata parameter on /admin/foreigner-search.php.
• Review database audit logs for evidence of prior exploitation, including suspicious UNION or schema enumeration queries.

Patch Information

No vendor advisory or official patch has been published for PHPGurukul Zoo Management System 2.1 at the time of NVD publication. Operators should monitor the PHPGurukul project page for updates and apply any subsequent releases. Until a fix ships, customers should treat the application as exposed and apply the workarounds below.

Workarounds

• Modify the affected source to use parameterized queries via mysqli_prepare or PDO with bound parameters instead of string concatenation.
• Implement server-side input validation that rejects non-alphanumeric characters in the searchdata field.
• Disable or remove the foreigner search feature if it is not required for business operations.
• Place the application behind an authenticated reverse proxy to reduce exposure of the admin interface.
