CVE-2024-11313 describes a critical Path Traversal vulnerability affecting TRCore DVC versions 6.0 through 6.3. This flaw allows unauthenticated attackers to upload arbitrary files, potentially enabling remote code execution. The vulnerability stems from insufficient file type restrictions during uploads. A patch is available in version 6.3.1.
The impact of this vulnerability is severe. An attacker can leverage the Path Traversal flaw to upload malicious files, such as webshells, to any directory on the server. Successful exploitation grants the attacker the ability to execute arbitrary code, potentially leading to complete system compromise, data exfiltration, and denial of service. The lack of authentication requirements significantly broadens the attack surface, making the system vulnerable to widespread exploitation. This vulnerability shares similarities with other file upload vulnerabilities where inadequate validation allows attackers to bypass security controls and gain unauthorized access.
CVE-2024-11313 was publicly disclosed on November 18, 2024. The vulnerability's severity (CVSS 9.8) indicates a high probability of exploitation. No KEV listing is currently available. Public proof-of-concept (PoC) code is not yet widely available, but the ease of exploitation suggests it is likely to emerge. Monitor security advisories and threat intelligence feeds for updates.
Organizations utilizing TRCore DVC versions 6.0 through 6.3 are at significant risk. This includes deployments where file uploads are a core functionality and where access controls are not strictly enforced. Shared hosting environments using TRCore DVC are particularly vulnerable due to the potential for cross-tenant exploitation.
• other / general: Monitor web server access logs for unusual file upload patterns, particularly attempts to access files outside of designated upload directories. Look for requests containing directory traversal sequences (e.g., ../).
• other / general: Inspect the DVC installation directory for unexpected files, especially those with executable extensions (e.g., .php, .asp, .jsp).
• other / general: Review DVC configuration files for any insecure file upload settings or missing validation checks.

The primary mitigation for CVE-2024-11313 is to upgrade TRCore DVC to version 6.3.1 or later, which includes the necessary fix. If immediate upgrading is not possible, consider implementing temporary workarounds. Restrict file uploads to only explicitly allowed file types using web server configuration (e.g., .htaccess for Apache, nginx.conf for Nginx). Implement strict file naming conventions to prevent attackers from manipulating file paths. Consider using a Web Application Firewall (WAF) to filter out malicious file uploads and block attempts to access unexpected file locations. Regularly scan the file system for suspicious files and monitor upload logs for unusual activity.
将 DVC 更新到 6.3 版本之后的版本以修复路径遍历漏洞和缺乏文件类型限制。这将防止通过上传 webshells 导致任意代码执行。请参阅版本说明以获取具体的升级说明。
