CVSS measures technical severity, not the likelihood of an attack.

Known exploitation

Not listed in the checked CISA KEV catalog

Absence from CISA KEV does not rule out attacks.

Public exploit

Not established by this record

Missing evidence does not mean no public exploit exists.

Remediation

Source guidance available

Review the recorded instructions. Guidance may be a workaround rather than a fixed version.

What this means

Zenitel devices with software versions before 10.1.3.0 have a path traversal vulnerability in the certificate upload endpoint, allowing authenticated administrators to write arbitrary files as root. The vulnerability affects VSFF6, VSFF8, VSFF8MP, VSFF8MN, and VSFT devices. An attacker must have administrator access to exploit the weakness.

Summarized by @cf/meta/llama-3.3-70b-instruct-fp8-fast. Verify details against the original sources.

What to do

Compare your installed product and version with the affected versions above. A matching product name alone does not confirm exposure.

Affected devices should upgrade to version 10.1.3.0 (and newer).

Public exploit evidence

No public exploit reference is identified in the imported evidence. This is not a claim that no exploit exists.

Original source description

Read the full publisher description

Path traversal in the certificate upload endpoint (/api/certificate/upload) 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 write arbitrary files as root via a crafted filename parameter in a multipart upload request when the type field is set to any value other than https_certificate. In that case, both path validation and certificate content validation are skipped.

This can be escalated to arbitrary code execution as root, for example by overwriting startup scripts or planting SSH keys.
