This issue affects an unknown functionality of the component Diagnostic Telnet Mode. The manipulation with an unknown input leads to a os command injection vulnerability. Using CWE to declare the problem leads to CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. Impacted is confidentiality, integrity, and availability.

The weakness was disclosed 12/29/2023 by Christoph Wolff and Pascal Zenker with modzero AG as MZ-23-01. The advisory is shared at modzero.com. The identification of this vulnerability is CVE-2023-4464. Technical details are unknown but a public exploit is available. MITRE ATT&CK project uses the attack technique T1202 for this issue. The advisory points out:

Poly devices include a diagnostic Telnet mode, which allows an administrator to execute a restricted set of commands, once the mode has been enabled via configuration. Some of these commands are not properly validated and allow for OS command injection as the root user.

The exploit is available at github.com. It is declared as proof-of-concept.

Upgrading eliminates this vulnerability.
