Missing Authentication for Critical Function in TR7 Cyber ​​Defense's TR7 ASP

Published Oct 14, 2026 CVSS 3.1 · 9.8 Critical EPSS 1.7% KEV · Not listed
Description
Missing authentication for critical function vulnerability in TR7 Cyber ​​Defense Inc. TR7 ASP on virtual appliance and TR7 Cyber ​​Defense Inc. TR7 ASP on physical appliance allows OS Command Injection.

This issue affects TR7 ASP: from 1.0.40.236 before 1.0.1554.2331; TR7 ASP: from 1.6.42.239 before 1.6.1554.2331.

Analysis

AI-generated

Technical impact

The vulnerability is a missing authentication flaw that allows an unauthenticated user to trigger a critical function in TR7 ASP. This flaw enables the execution of arbitrary operating‑system commands, giving the attacker full control over the affected appliance. The weakness is identified as CWE‑306, which indicates that authentication checks are absent for a privileged operation. The impact is severe, as the attacker can gain full system compromise, leading to confidentiality, integrity, and availability damage.

Affected Systems

TR7 Cyber Defense Inc. provides the TR7 ASP product, which is available as a virtual and a physical appliance. The vulnerability affects versions from 1.0.40.236 up to, but not including, 1.0.1554.2331, and from 1.6.42.239 up to, but not including, 1.6.1554.2331. Systems running these firmware revisions possess an unauthenticated entry point that can be abused for command injection.

Risk and Exploitability

The CVSS score of 9.8 reflects the high severity of the flaw; the EPSS score of 2% indicates a low but non‑zero exploitation probability. The vulnerability is not listed in the CISA KEV catalog. Based on the description and typical deployment scenarios, the likely attack vector is a remote network connection to a management interface, where the absence of authentication allows the attacker to invoke the vulnerable function. Without authentication, the attacker can immediately achieve full remote code execution on the appliance.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Apply the vendor‑released upgrade to TR7 ASP version 1.0.1554.2331 or later in the 1.0 series, or 1.6.1554.2331 or later in the 1.6 series.
  • If an upgrade cannot be performed immediately, restrict access to the appliance by implementing firewall rules or network segmentation that limit contact to trusted hosts.
  • As a temporary workaround, disable the critical function that accepts unauthenticated input or remove it from the appliance’s configuration until the patched firmware is available.
