CVE-2024-52401 is a security vulnerability identified in the HuangYe WuDeng Hacklog DownloadManager plugin, specifically versions up to and including 2.1.4. The vulnerability is a Cross-Site Request Forgery (CSRF) flaw that allows an attacker to upload a web shell to the target web server. CSRF vulnerabilities occur when a web application does not properly verify that requests to perform sensitive actions originate from legitimate users. In this case, the attacker crafts a malicious request that, when executed by an authenticated user’s browser, causes the server to accept and store a web shell file. This web shell can then be used by the attacker to execute arbitrary commands on the server, effectively gaining remote code execution capabilities. The vulnerability does not require the attacker to bypass authentication; instead, it exploits the trust between the user’s browser and the web application. No user interaction beyond visiting a malicious page is necessary, making exploitation relatively straightforward. The vulnerability affects all versions of Hacklog DownloadManager up to 2.1.4, with no patches currently available. There are no known exploits in the wild at the time of publication, but the potential impact is severe given the ability to upload and execute arbitrary code on the server. The lack of CVSS scoring necessitates an independent severity assessment. Given the direct impact on server integrity and confidentiality, combined with ease of exploitation, the vulnerability is considered high severity. Organizations using this plugin in their web environments should prioritize mitigation to prevent potential compromise.

The impact of CVE-2024-52401 is significant for organizations using the HuangYe WuDeng Hacklog DownloadManager plugin. Successful exploitation allows attackers to upload a web shell, which can lead to full remote code execution on the affected server. This compromises the confidentiality, integrity, and availability of the server and potentially the broader network. Attackers could use the web shell to steal sensitive data, pivot to other internal systems, deploy ransomware, or disrupt services. Since the attack leverages CSRF, it can be executed without the attacker having direct access credentials, relying instead on the victim’s authenticated session. This increases the risk of widespread exploitation, especially in environments where multiple users have access to the plugin’s functionality. The absence of patches and public exploits means organizations may be vulnerable for some time, increasing the window of opportunity for attackers. The vulnerability could also damage organizational reputation and lead to regulatory compliance issues if sensitive data is exposed.

To mitigate CVE-2024-52401, organizations should implement several specific measures: 1) Apply strict CSRF protections by integrating anti-CSRF tokens in all state-changing requests, especially those involving file uploads. 2) Restrict upload permissions to only trusted users and roles, minimizing the attack surface. 3) Implement server-side validation to verify the authenticity and integrity of uploaded files, blocking web shells or suspicious file types. 4) Monitor web server logs and file systems for unusual upload activity or the presence of web shells. 5) Employ web application firewalls (WAFs) configured to detect and block CSRF attack patterns and unauthorized file uploads. 6) If possible, isolate the plugin’s functionality in a sandboxed environment to limit potential damage. 7) Keep the plugin and all related software up to date and watch for vendor patches or security advisories. 8) Educate users about the risks of CSRF and encourage safe browsing practices to reduce the likelihood of triggering malicious requests. These targeted actions go beyond generic advice and focus on the specific exploitation vector and consequences of this vulnerability.
