TR7 ASP: OS command injection
Summary
TR7 ASP appliances, both virtual and physical, contain an OS command injection vulnerability (CWE-78). Depending on the NVD and CNA data, an attacker may be able to run operating system commands on the appliance over the network. The CVSS 3.1 base score is 9.8 according to NVD-related sources; VulDB rates it 10.0. No authentication or user interaction is required according to the CVSS vector, but NVD analysis is still pending.
Affected
- TR7 ASP from 1.0.40.236 before 1.0.1554.2331
- TR7 ASP from 1.6.42.239 before 1.6.1554.2331
- Both virtual and physical appliances
Fixed in
- Upgrade to 1.0.1554.2331 (1.0.x branch)
- Upgrade to 1.6.1554.2331 (1.6.x branch)
- Confirm the exact build against the Turkish national CERT advisory and the vendor, as the vendor bulletin could not be retrieved.
Workaround
Unknown.
- No vendor or CERT workaround has been found. Restrict access to the management interface to trusted administrator networks until patched.
Exploitation
- No confirmed in-the-wild exploitation; CISA KEV lists it as not included.
- No public proof of concept found.
- VulDB states that no exploit is available but describes exploitation as easy and remotely initiable.
- EPSS is about 0.017 (low).
Our recommendation
- Identify all TR7 ASP appliances (physical and virtual) and their exact build numbers. Do not confuse them with T&D TR-7 data loggers.
- Upgrade to 1.0.1554.2331 or 1.6.1554.2331 as applicable, and verify the build.
- Until patched, remove internet exposure of the management interface and limit access to admin networks.
- Check logs for unexpected administrative activity.
- Also review related CVE-2026-16740, published the same day and covering the same versions.
- Re-check NVD, CISA KEV and VulDB, as the status may change.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
