CVE-2024-8256

Status: DeferredMedium (5.9)—

In Teltonika Networks RUTOS devices, running on versions 7.0 to 7.8 (excluding) and TSWOS devices running on versions 1.0 to 1.3 (excluding), due to incorrect permission handling a vulnerability exists which allows a lower privileged user with default permissions to access critical device resources via the API.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
