CVE-2025-2053: Apartment Visitors Management SQL Injection

CVE-2025-2053 Overview

CVE-2025-2053 is a SQL injection vulnerability in PHPGurukul Apartment Visitors Management System version 1.0. The flaw resides in the /visitor-detail.php script, where the editid request parameter is concatenated into a SQL query without proper sanitization. Remote attackers can manipulate this parameter to inject arbitrary SQL statements against the backend database. The issue is tracked under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command) and CWE-74 (Injection). Exploit details have been publicly disclosed, increasing the likelihood of opportunistic attacks against exposed instances.

Critical Impact
Authenticated remote attackers can inject SQL via the editid parameter in /visitor-detail.php, enabling unauthorized read or modification of visitor records stored in the application database.

Affected Products

PHPGurukul Apartment Visitors Management System 1.0
Deployments using the vulnerable /visitor-detail.php endpoint

Technical Details for CVE-2025-2053

Vulnerability Analysis

The vulnerability is an SQL injection in the visitor-detail.php script of the PHPGurukul Apartment Visitors Management System. The application accepts the editid parameter from a remote client and embeds it directly into a SQL statement that retrieves or updates visitor records. Because input is not validated, escaped, or bound through parameterized queries, an attacker can append SQL syntax such as boolean conditions, UNION SELECT statements, or stacked queries.

Exploitation requires only low-privileged access to the application and can be performed remotely over the network. Successful injection exposes visitor identity data, login credentials stored in the database, and supporting administrative tables. Depending on the database account privileges, attackers may also modify or delete records.

Root Cause

The root cause is improper neutralization of user-supplied input before its inclusion in an SQL query. The editid parameter is treated as trusted data rather than as an untrusted string requiring binding. The codebase does not use prepared statements or parameterized queries, which would otherwise separate query logic from data.

Attack Vector

The attack vector is network-based and targets the /visitor-detail.php endpoint. An attacker sends a crafted HTTP request containing a malicious editid value. The injected SQL is then executed by the backend database in the context of the application user. The public disclosure of exploit details lowers the technical barrier to abuse.

No verified proof-of-concept code is referenced in this advisory. Technical specifics are tracked in the GitHub issue and the VulDB entry #298806.

Detection Methods for CVE-2025-2053

Indicators of Compromise

HTTP requests to /visitor-detail.php containing SQL metacharacters such as single quotes, UNION, SELECT, --, /*, or OR 1=1 in the editid parameter.
Web server access logs showing unusually long or URL-encoded editid values from a single source IP address.
Database error messages or HTTP 500 responses correlated with requests to visitor-detail.php.
Unexpected outbound queries from the PHP application user against sensitive tables such as admin or users.

Detection Strategies

Deploy a web application firewall (WAF) ruleset that inspects query strings for SQL injection patterns targeting the editid parameter.
Enable verbose MySQL or MariaDB query logging during incident response to identify injected UNION and stacked queries.
Correlate web access logs with database audit logs to detect anomalous record retrieval volumes from visitor-detail.php.

Monitoring Recommendations

Alert on repeated 4xx or 5xx responses from /visitor-detail.php, which often indicate injection probing.
Monitor for new or unexpected administrative accounts created in the application database after suspicious traffic.
Track outbound data volume from the web server to identify large database extraction events.

How to Mitigate CVE-2025-2053

Immediate Actions Required

Restrict public exposure of the Apartment Visitors Management System until a vendor patch is applied.
Block or rate-limit requests to /visitor-detail.php that contain SQL syntax in the editid parameter at the WAF or reverse proxy layer.
Audit existing visitor and administrative records for signs of tampering or unauthorized inserts.
Rotate database credentials used by the application if injection activity is suspected.

Patch Information

At the time of publication, no vendor-issued security patch is listed in the NVD references for CVE-2025-2053. Administrators should monitor the PHPGurukul site for an updated release of the Apartment Visitors Management System and apply it as soon as it becomes available.

Workarounds

Place the application behind a WAF with signatures for SQL injection targeting PHP parameter names.
Modify visitor-detail.php locally to use PDO prepared statements or mysqli parameterized queries for the editid parameter.
Enforce least-privilege on the database account used by the application, removing rights to write to administrative tables.
Disable detailed SQL error output in PHP by setting display_errors = Off in php.ini to limit information leakage.
