CVE-2020-7534

Unknown · Web Server

A Cross-Site Request Forgery (CSRF) vulnerability exists in the web server, potentially allowing unauthorized actions while a user is authenticated.

Executive summary

A Cross-Site Request Forgery (CSRF) vulnerability in the web server could permit unauthorized actions or sensitive data disclosure if an authenticated user is tricked into visiting a malicious site.

Vulnerability

This is a CWE-352 (CSRF) vulnerability. It allows an attacker to perform unauthorized actions on behalf of an authenticated user by leveraging the user's active session on the web server.

Business impact

With a CVSS score of 8.8, this vulnerability poses a significant risk to data confidentiality and integrity. If exploited, an attacker could perform administrative actions or extract sensitive information without the user's knowledge, potentially leading to a broader compromise of the web application.

Remediation

Immediate Action: Update the affected web server software to the latest version provided by the vendor to implement proper CSRF protection tokens.

Proactive Monitoring: Monitor web server access logs for anomalous request patterns, particularly those originating from unexpected referrers or lacking expected anti-CSRF tokens.

Compensating Controls: Deploy a Web Application Firewall (WAF) configured with rules to detect and block CSRF attempts, and ensure all sensitive endpoints strictly enforce anti-CSRF tokens.

Exploitation status

Public Exploit Available: false

Analyst recommendation

CSRF vulnerabilities are often overlooked but can lead to severe security breaches. It is recommended that administrators prioritize updating the web server software and perform a thorough audit of the application's session management and token validation practices to ensure robust protection.
