CVE-2020-37172: AVideo Platform 8.1 CSRF Vulnerability

CVE-2020-37172 Overview

CVE-2020-37172 is a Cross-Site Request Forgery (CSRF) vulnerability affecting AVideo Platform 8.1 that allows attackers to reset user passwords by exploiting the password recovery mechanism. Attackers can craft malicious requests to the recoverPass endpoint using the user's recovery token to change account credentials without authentication. This vulnerability poses a significant risk to organizations utilizing AVideo Platform for video hosting and streaming services.

Critical Impact

Attackers can hijack user accounts by resetting passwords without proper authentication, potentially leading to complete account takeover and unauthorized access to video content and administrative functions.

Technical Details for CVE-2020-37172

Vulnerability Analysis

This vulnerability exists in the password recovery mechanism of AVideo Platform 8.1. The application fails to implement proper CSRF protection on the password reset functionality, allowing an attacker to forge requests that change a user's password. When a user initiates a password recovery, the system generates a recovery token. However, the subsequent password change request via the recoverPass endpoint does not validate that the request originated from the legitimate user's session, making it vulnerable to cross-site request forgery attacks.

The weakness is classified as CWE-640 (Weak Password Recovery Mechanism for Forgotten Password), indicating that the password recovery implementation lacks sufficient security controls to prevent unauthorized password changes.

Root Cause

The root cause of this vulnerability is the absence of CSRF tokens or other request validation mechanisms in the password recovery workflow. The recoverPass endpoint processes password change requests without verifying that they originated from the same user session that initiated the recovery process. This allows an attacker who obtains or guesses a user's recovery token to craft a malicious request that changes the victim's password.

Attack Vector

The attack is network-based and requires user interaction. An attacker must first obtain or predict a valid recovery token for a target user. The attacker then crafts a malicious HTML page or email containing a hidden form that submits a password reset request to the vulnerable recoverPass endpoint. When the victim visits the attacker's page while authenticated or clicks a malicious link, the forged request is sent to the AVideo server, changing the victim's password to one controlled by the attacker. This grants the attacker full access to the compromised account.

The attack leverages the trust relationship between the user's browser and the AVideo application, as the server cannot distinguish between legitimate password reset requests and forged ones submitted by an attacker's page.

Detection Methods for CVE-2020-37172

Indicators of Compromise

• Unexpected password reset requests in application logs, particularly multiple resets for the same user in a short time period
• User reports of unauthorized account access or password changes they did not initiate
• Suspicious HTTP POST requests to the recoverPass endpoint originating from external referrers
• Recovery tokens being used from IP addresses different from where they were originally requested

Detection Strategies

• Monitor web application logs for password reset requests with unusual referrer headers or missing CSRF tokens
• Implement anomaly detection for password recovery patterns, flagging accounts with multiple reset attempts
• Correlate password reset events with subsequent login attempts from new IP addresses or geolocations
• Deploy web application firewalls (WAF) with rules to detect CSRF attack patterns targeting authentication endpoints

Monitoring Recommendations

• Enable detailed logging for all authentication-related endpoints including password recovery functions
• Configure alerting for password reset activity that exceeds normal baseline thresholds
• Monitor for suspicious form submissions to the recoverPass endpoint from external domains
• Track and alert on successful logins following password resets, particularly from new devices or locations

How to Mitigate CVE-2020-37172

Immediate Actions Required

• Upgrade AVideo Platform to the latest available version that addresses this CSRF vulnerability
• Implement CSRF token validation on all state-changing endpoints, including password recovery
• Review recent password reset logs for signs of exploitation and notify affected users
• Consider temporarily disabling the password recovery feature until a patch can be applied

Patch Information

Organizations should check the GitHub Repository for AVideo for the latest security updates and patches. Additional vulnerability details are available in the Vulncheck Advisory for AVideo CSRF and Exploit-DB #48003.

Workarounds

• Implement a web application firewall (WAF) rule to validate the Referer and Origin headers on requests to the recoverPass endpoint
• Add rate limiting on password recovery endpoints to slow down potential exploitation attempts
• Require additional verification steps for password resets, such as email confirmation links that expire quickly
• Consider implementing SameSite cookie attributes to prevent cross-site request submission
• Educate users about phishing attacks and advise them to report any suspicious password reset notifications

If applying patches immediately is not possible, administrators can add custom CSRF protection at the web server or application proxy level by validating that password reset requests contain expected headers and originate from the same domain.
