CVE-2025-57310: Simple Faucet Script CSRF Vulnerability

CVE-2025-57310 Overview

A Cross-Site Request Forgery (CSRF) vulnerability has been identified in Salmen2/Simple-Faucet-Script version 1.07. The vulnerability exists in the administrative interface via crafted POST requests to the admin.php?p=ads&c=1 endpoint. Successful exploitation allows attackers to execute arbitrary code by tricking authenticated administrators into unknowingly submitting malicious requests, potentially leading to complete compromise of the affected application.

Critical Impact

Unauthenticated attackers can leverage this CSRF vulnerability to execute arbitrary code on affected systems by crafting malicious requests and luring authenticated administrators to trigger them, potentially resulting in full system compromise.

Technical Details for CVE-2025-57310

Vulnerability Analysis

This CSRF vulnerability (CWE-352) occurs due to the absence of proper anti-CSRF token validation in the administrative panel of Simple-Faucet-Script. The admin.php endpoint, specifically when handling ad-related operations at the ?p=ads&c=1 parameter path, fails to verify that incoming POST requests originate from legitimate user actions within the application.

The vulnerability allows attackers to craft malicious HTML pages or links that, when visited by an authenticated administrator, will cause the victim's browser to automatically submit forged requests to the vulnerable endpoint. Since the application does not implement CSRF protections such as unique tokens, origin validation, or SameSite cookie attributes, the malicious requests are processed as if they were legitimate administrative actions.

The impact is significant as successful exploitation can lead to arbitrary code execution. This indicates that the ad management functionality likely allows the injection of server-side code or scripts that are subsequently executed by the application.

Root Cause

The root cause of this vulnerability is the lack of CSRF protection mechanisms in the administrative interface of Simple-Faucet-Script. Specifically:

1. The admin.php endpoint does not implement anti-CSRF tokens to validate the origin of requests
2. No verification of the Referer or Origin HTTP headers is performed
3. Session cookies are not protected with the SameSite attribute
4. The application accepts POST requests from any origin without validation

This design flaw allows cross-origin requests to perform administrative actions when an authenticated administrator is tricked into visiting an attacker-controlled page.

Attack Vector

The attack leverages the network-accessible administrative interface and requires user interaction from an authenticated administrator. An attacker would typically:

1. Craft a malicious HTML page containing a hidden form that targets the vulnerable admin.php?p=ads&c=1 endpoint
2. Include payload data in the form fields designed to inject malicious code through the ad management functionality
3. Host this malicious page on an attacker-controlled server or inject it into a legitimate website the target administrator might visit
4. Social engineer the administrator into visiting the malicious page while authenticated to the Simple-Faucet-Script admin panel
5. Upon page load, JavaScript automatically submits the forged request, executing the malicious payload with the administrator's privileges

Technical details and proof-of-concept information can be found in the GitHub Gist PoC and the CVE-2025-57310 Repository.

Detection Methods for CVE-2025-57310

Indicators of Compromise

• Unusual POST requests to admin.php?p=ads&c=1 originating from external referrers or with missing/unexpected Referer headers
• Administrative configuration changes occurring without corresponding legitimate admin login activity
• New or modified ad entries containing suspicious script tags, PHP code, or encoded payloads
• Web server logs showing requests to admin endpoints from IP addresses different from typical administrator access patterns
• Unexpected files or code modifications in the application directory following ad management operations

Detection Strategies

• Implement web application firewall (WAF) rules to monitor and alert on POST requests to administrative endpoints lacking proper origin validation
• Configure logging to capture and analyze all requests to admin.php endpoints, particularly those with external referrers
• Deploy SIEM rules to correlate admin actions with authentication events, flagging administrative changes without corresponding login activity
• Monitor for creation or modification of files in web-accessible directories that could indicate successful code injection

Monitoring Recommendations

• Enable verbose logging for all administrative actions in the Simple-Faucet-Script application
• Implement file integrity monitoring (FIM) on application directories to detect unauthorized code modifications
• Configure alerts for administrative endpoint access from unexpected geographic locations or IP ranges
• Regularly audit ad content and configuration entries for suspicious payloads or script injection attempts

How to Mitigate CVE-2025-57310

Immediate Actions Required

• Restrict access to the administrative interface (admin.php) by implementing IP-based access controls or VPN requirements
• Implement a web application firewall (WAF) with rules to block suspicious POST requests to administrative endpoints
• Review and audit all existing ad configurations for malicious payloads that may have been injected
• Consider temporarily disabling the ad management functionality until a patch is available or CSRF protections can be implemented
• Ensure administrators use separate browser profiles for administrative tasks and never browse untrusted websites while authenticated

Patch Information

As of the last update on December 31, 2025, no official vendor patch has been released for this vulnerability. The vendor (Salmen) has not published any security advisories addressing CVE-2025-57310. Users are advised to monitor the CVE-2025-57310 Repository for updates and consider implementing manual mitigations or custom patches.

Workarounds

• Manually implement CSRF token validation in the admin.php file by generating unique tokens per session and validating them on each POST request
• Add SameSite=Strict or SameSite=Lax attribute to session cookies to prevent cross-site request submission
• Implement origin validation by checking the Referer and Origin headers against a whitelist of allowed domains
• Use a reverse proxy to add an additional authentication layer before the administrative interface
• Consider migrating to a more actively maintained faucet script solution with proper security controls

# Example Apache .htaccess configuration to restrict admin access by IP
<Files "admin.php">
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.0/24
    Allow from 10.0.0.0/8
    # Add your trusted admin IP addresses/ranges
