CVE-2026-95379: Path traversal in Zenitel turbineweb certificate delete RPC allows arbitrary file deletion as root
Path traversal in the certificate.deleteCertificate JSON-RPC method (POST /api/rpc) of the turbineweb web interface in Zenitel VSFF6, VSFF8, VSFF8MP, VSFF8MN, and VSFT devices with software versions from 10.0.3.0 before 10.1.3.0 allows authenticated administrators to delete arbitrary files as root via a relative path (../) in the filename parameter.
This can be used to cause denial of service or render the device inoperable by removing critical system files, and to weaken device security by removing files such as firewall rules or certificate trust stores.
Event History
Frequently Asked Questions
Which devices and software versions are affected?
Zenitel VSFF6, VSFF8, VSFF8MP, VSFF8MN, and VSFT devices are affected when running software versions from 10.0.3.0 before 10.1.3.0.
What access does an attacker need?
An attacker must be authenticated as an administrator and able to send requests to the turbineweb web interface JSON-RPC endpoint at POST /api/rpc. No user interaction is required.
What could an attacker do with successful exploitation?
An authenticated administrator can delete arbitrary files with root privileges by supplying a relative path in the file_name parameter. This can cause denial of service, make the device inoperable, or weaken security by deleting firewall rules or certificate trust stores.
