CVE-2024-7694 TeamT5 ThreatSonar Anti-Ransomware Unrestricted Upload of File with Dangerous Type Vulnerability

What is CVE-2024-7694?

CVE-2024-7694 is an authenticated arbitrary file upload vulnerability in TeamT5 ThreatSonar Anti-Ransomware that can be leveraged for command execution on the server. The product’s management platform does not sufficiently validate uploaded file content/types, allowing a user with administrator privileges to upload a file that the server may later handle unsafely. If the uploaded file is processed in an execution-capable context, it can be used to run arbitrary system commands on the ThreatSonar server. This CVE has also been listed in CISA’s Known Exploited Vulnerabilities (KEV) catalog, indicating evidence of active exploitation.

What is Affected By CVE-2024-7694?

ThreatSonar Anti-Ransomware deployments running vulnerable versions (and exposing the admin platform) are affected. Public advisories identify ThreatSonar Anti-Ransomware 3.4.5 and earlier as impacted, with remediation guidance pointing to 3.5.0 or later as the fixed baseline. The vulnerable condition is associated with server-side file upload handling within the product platform (exact endpoints/paths are not broadly detailed in public advisories). Affected scope can differ by deployment model, but TeamT5 notes cloud deployments received the relevant hotfix by mid-July 2024.

• Affected product: TeamT5 ThreatSonar Anti-Ransomware

• Affected versions: 3.4.5 and earlier (i.e., versions prior to 3.5.0)

• Access required: Authenticated administrator on the product platform

• Likely affected area: Administrative file upload functionality where uploaded content/type validation is insufficient

Mitigation and Remediation For CVE-2024-7694

The primary remediation is to upgrade or apply the vendor-recommended hotfix immediately. TWCERT/CC’s guidance is to update to ThreatSonar Anti-Ransomware 3.5.0 or later or apply Hotfix-20240715 as a corrective patch. Because the issue requires admin-level access, hardening administrative authentication and limiting exposure of the management interface meaningfully reduces risk, but it should not be treated as a substitute for patching. Given KEV status, organizations should treat remediation as urgent; if you cannot mitigate, CISA guidance (as reflected in NVD’s KEV section) indicates discontinuing use may be necessary.

• Patch/upgrade (preferred):

  • Upgrade to ThreatSonar Anti-Ransomware 3.5.0 or later

  • Or apply Hotfix-20240715 (vendor-provided hotfix path)

• Reduce exposure of the admin platform:

  • Restrict management UI access to VPN/internal networks and allowlisted IPs

  • Enforce MFA for all administrator accounts and rotate admin credentials

  • Audit/admin review: remove unused admins and apply least privilege

• Add compensating controls & monitoring:

  • Log and alert on file upload events and unexpected file types

  • Monitor for new or unusual processes spawned by the ThreatSonar server

  • Use host controls (e.g., application allowlisting) to prevent unexpected execution from upload/temp directories

Impact of Successful Exploitation of CVE-2024-7694

Successful exploitation can enable an attacker (with admin access) to execute commands on the ThreatSonar server and potentially take full control of the system. This can undermine both the availability and trustworthiness of the security platform itself, especially if the attacker modifies configurations, disables protections, or pivots to other internal systems. Because exploitation requires administrator privileges, it may be combined with credential theft, account takeover, or other access pathways in real incidents. Public reporting notes that the specific in-the-wild exploitation details have not been widely disclosed, but KEV inclusion indicates real-world abuse.

• Potential impacts include:

  • Arbitrary system command execution on the ThreatSonar server

  • Compromise of monitoring/response capabilities (tampered policies, disabled agents, altered alerting)

  • Data exposure (logs, incident artifacts, host identifiers, operational details)

  • Lateral movement into connected networks if the server has privileged connectivity

  • Service disruption or forced downtime if the platform is destabilized or intentionally damaged

Proof of Concept for CVE-2024-7694

As of the latest check, public write-ups acknowledge exploitation but do not provide detailed, reproducible exploit steps or a widely accepted public PoC for this specific product workflow. Reporting indicates it’s unclear exactly how the vulnerability is being weaponized in the wild, and vendor/CERT advisories focus on patching rather than publishing technical exploit chains. The safest way to validate exposure is a controlled, authorized test that checks whether the admin UI accepts “dangerous” file types or mismatched content-types when attempting an upload. The examples below are educational/defensive templates and intentionally omit product-specific endpoints and post-upload execution steps.

• Defensive validation approach (authorized testing only):

  • In a non-production environment, log in as an administrator and identify the UI feature that performs file uploads.

  • Capture the upload request with your proxy/browser dev tools, then attempt to upload a benign test file using a dangerous extension (e.g., .jsp, .php, .aspx) or a content/extension mismatch.

  • If the platform accepts the upload without validation and stores it in a risky location, treat the instance as vulnerable and patch immediately.
