Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

AC-6 Least Privilege good match

prevent

Enforces the principle of least privilege, directly mitigating CWE-269 by ensuring resources in Mitel OpenScape 4000 are not executed with unnecessary elevated privileges, preventing authenticated low-privilege attackers from escalating to arbitrary command execution.

AC-3 Access Enforcement good match

prevent

Requires enforcement of approved access authorizations, preventing privilege escalation in the Platform component by blocking unauthorized elevation during resource execution.

CM-7 Least Functionality partial match

prevent

Restricts the system to least functionality, reducing the attack surface by eliminating unnecessary capabilities in OpenScape 4000 that could execute with excessive privileges.

NVD Description

The Platform component of Mitel OpenScape 4000 and OpenScape 4000 Manager through V10 R1.54.1 and V11 through R0.22.1 could allow an authenticated attacker to conduct a privilege escalation attack due to the execution of a resource with unnecessary privileges. A…

successful exploit could allow an attacker to execute arbitrary commands with elevated privileges.

Deeper analysisAI

CVE-2025-23093 is a privilege escalation vulnerability in the Platform component of Mitel OpenScape 4000 and OpenScape 4000 Manager, affecting versions through V10 R1.54.1 and V11 through R0.22.1. The issue arises from the execution of a resource with unnecessary privileges, classified under CWE-269 (Improper Privilege Management). It has a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to its potential for significant confidentiality, integrity, and availability impacts.

An authenticated attacker with low privileges (PR:L) can exploit this vulnerability remotely over the network (AV:N) with low complexity and no user interaction required. Successful exploitation enables the execution of arbitrary commands with elevated privileges, potentially granting full system compromise.
