Description

CVE-2024-57241 is a URL redirection vulnerability affecting Dedecms 5.71sp1 and earlier. A logic error in the application fails to validate input GET requests, leading to potential redirection to arbitrary URLs. While the CVSS score is 5.1, indicating a medium severity, the SOCRadar Vulnerability Risk Score (SVRS) of 30 suggests the real-world risk associated with this vulnerability is not critical. However, it's important to note that it is tagged "In The Wild", this means the vulnerability is actively exploited by hackers.

Key Insights

1. Unvalidated Input: The core issue is the lack of input validation for GET requests. This allows attackers to craft malicious URLs that redirect users to phishing sites or other harmful destinations.
2. Impact of Redirection: Successful exploitation can lead to credential theft (if the redirection leads to a fake login page), malware distribution (if the redirection leads to a malicious download), or reputational damage to the legitimate website.
3. In The Wild Exploitation: The "In The Wild" tag signifies active exploitation, increasing the urgency of addressing this vulnerability, even with a lower SVRS. This means that attackers are actively searching for and exploiting vulnerable Dedecms instances.

Mitigation Strategies

1. Input Validation and Sanitization: Implement robust input validation and sanitization for all GET requests, specifically focusing on URL parameters. Use allow lists to define acceptable URL patterns and reject any requests that deviate from these patterns.
2. Update Dedecms: Upgrade to the latest version of Dedecms, if a patched version is available. Check the vendor's website for security updates and release notes.
3. Web Application Firewall (WAF): Deploy a WAF to detect and block malicious URL redirection attempts. Configure the WAF with rules to identify and prevent common URL redirection attacks.
4. Regular Security Audits: Conduct regular security audits and penetration testing to identify and address vulnerabilities in your Dedecms installation. These audits should include a review of input validation and redirection mechanisms.
