Vulnerability Details
CVE-2025-7024 pertains to an Incorrect Default Permissions vulnerability in the AIRBUS PSS TETRA Connectivity Server on Windows Server OS. Specifically, it allows privilege abuse, permitting an attacker to execute arbitrary code with SYSTEM privileges if a user is manipulated into placing a crafted file in the vulnerable directory. This vulnerability impacts version 7.0 of the TETRA Connectivity Server.
The vulnerability is characterized by a CVSS 4.0 score of 5.6, indicating a medium severity level. The attack vector is classified as local, and the attack complexity is low, requiring only user interaction. The confidentiality, integrity, and availability impacts are all rated as high.
The vulnerability was published on April 3, 2026, and it falls under the CWE-276 classification for incorrect default permissions.
Technical Analysis
The root cause of this vulnerability is linked to the incorrect configuration of default permissions within the AIRBUS PSS TETRA Connectivity Server. This misconfiguration allows unauthorized file placement in a directory that can lead to privilege escalation.
The attack vector for this vulnerability is local, meaning that an attacker must have some level of access to the system. The attack complexity is low, as it does not require any advanced skills or resources to exploit. A user must interact with the system for the attack to be successful, as they need to place a crafted file in the vulnerable directory.
The impacts of this vulnerability are severe, with high potential for confidentiality, integrity, and availability breaches. The attacker may gain full control over the affected system, leading to significant risks for the organization.
Risk & Impact Analysis
Real-world deployment of the AIRBUS PSS TETRA Connectivity Server with this vulnerability poses substantial risks to organizations. If successfully exploited, attackers may gain unauthorized access to sensitive systems and data, compromising the confidentiality and integrity of critical operations. The blast radius potential is significant, especially in environments where TETRA services are vital for communication.
Given the medium severity rating and the nature of the impacts, organizations should assess the urgency of addressing this vulnerability. It is advisable to prioritize it within the patch cycle, especially in systems that rely heavily on the TETRA Connectivity Server.
Organizations should also be aware of the potential for social engineering attacks that could facilitate exploitation. Training users to recognize and report suspicious activities can serve as an additional layer of defense.
