CVE-2026-95378

HIGHCVSS 8.6/10

Last modified

CVE-2026-95378 is a high-severity vulnerability rated 8.6/10 on the CVSS scale. 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..
