CVE-2023-32348

Teltonika’s Remote Management System versions prior to 4.10.0 contain a virtual private network (VPN) hub feature for cross-device communication that uses OpenVPN. It connects new devices in a manner that allows the new device to communicate with all Teltonika devices connected to the VPN. The OpenVPN server also allows users to route through it. An attacker could route a connection to a remote server through the OpenVPN server, enabling them to scan and access data from other Teltonika devices connected to the VPN.

Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.

Scope (S:C)
Breaking this can reach past the original component and bite other resources—bigger blast radius.
Confidentiality (C:L)
Some sensitive info could get out, but not a total data dump.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
