CVE-2025-5435: Marwal Infotech CMS SQL Injection Flaw

CVE-2025-5435 Overview

CVE-2025-5435 is a SQL injection vulnerability in Marwal Infotech CMS 1.0. The flaw resides in the /page.php script, where the ID parameter is passed directly into a database query without proper sanitization. Remote, unauthenticated attackers can manipulate the ID argument to inject arbitrary SQL statements. The exploit has been publicly disclosed and may be used in opportunistic attacks. The vendor was contacted but did not respond to disclosure attempts, leaving deployments without an official patch.

Critical Impact
Unauthenticated remote attackers can extract, modify, or delete database contents by injecting SQL through the ID parameter of /page.php.

Affected Products

Marwal Infotech CMS version 1.0
Deployments exposing /page.php to untrusted networks
Web applications using the unpatched CMS codebase

Technical Details for CVE-2025-5435

Vulnerability Analysis

The vulnerability is a classic SQL injection flaw classified under [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component). The ID parameter accepted by /page.php flows directly into a backend SQL query without parameterization or input filtering. An attacker can append SQL metacharacters and additional clauses to alter query logic.

Successful exploitation enables retrieval of database records, authentication bypass through query manipulation, and possible modification of stored content. The attack requires no authentication, no user interaction, and can be launched over the network against any reachable instance.

The EPSS score is 0.174% with a percentile of 38.4, reflecting current exploitation likelihood telemetry. Because the vendor has not responded to disclosure, no official patch exists, and administrators must apply compensating controls.

Root Cause

The root cause is the absence of input validation and prepared statements when handling the ID parameter in /page.php. User-supplied data is concatenated directly into the SQL query string. This pattern allows attacker-controlled syntax to escape the intended query context and execute additional statements.

Attack Vector

Attackers craft HTTP requests targeting /page.php?ID=<payload> with SQL injection strings such as boolean conditions, UNION SELECT clauses, or time-based blind payloads. The attack is fully remote and requires only network reachability to the affected web server. Public disclosure on GitHub provides working payload examples that lower the barrier to exploitation. Refer to the GitHub SQL Injection Report for technical proof-of-concept details.

Detection Methods for CVE-2025-5435

Indicators of Compromise

HTTP requests to /page.php containing SQL keywords such as UNION, SELECT, SLEEP, or OR 1=1 in the ID parameter
Unusual database error responses returned to clients following requests against /page.php
Outbound database connections originating from the web server during anomalous query bursts
Web server access logs showing encoded characters such as %27, %22, or %2D%2D in the ID parameter

Detection Strategies

Deploy web application firewall (WAF) rules that flag SQL metacharacters in the ID query parameter of /page.php
Enable database query logging and correlate slow or malformed queries with web request timestamps
Monitor for HTTP 500 responses tied to /page.php that may indicate failed injection attempts
Use signature-based intrusion detection rules tuned for SQL injection patterns against the affected endpoint

Monitoring Recommendations

Aggregate web server, WAF, and database logs into a central SIEM for correlation
Alert on repeated requests from a single source containing SQL syntax in URL parameters
Track baseline request volume to /page.php and alert on statistical anomalies
Review authentication and data-access audit trails for unauthorized record retrieval following suspect requests

How to Mitigate CVE-2025-5435

Immediate Actions Required

Restrict public access to Marwal Infotech CMS 1.0 instances until a fix is available
Place affected applications behind a WAF with SQL injection signatures enabled in blocking mode
Audit database accounts used by the CMS and enforce least-privilege permissions
Review web and database logs for indicators of prior exploitation against /page.php

Patch Information

No vendor patch is available. The vendor did not respond to coordinated disclosure attempts. Organizations operating Marwal Infotech CMS 1.0 should evaluate migrating to an actively maintained CMS platform. Track updates via VulDB #310768 for any future remediation guidance.

Workarounds

Implement WAF rules that reject non-numeric values supplied to the ID parameter of /page.php
Add a reverse proxy filter that validates ID against an integer-only regular expression before forwarding requests
Configure the CMS database user with read-only permissions where business logic permits
Isolate the CMS server in a segmented network with strict egress filtering to limit data exfiltration

bash

# Example nginx configuration to enforce numeric ID parameter
location /page.php {
    if ($arg_ID !~ ^[0-9]+$) {
        return 400;
    }
    proxy_pass http://cms_backend;
}
