CVE-2025-0921: Execution with Unnecessary Privileges vulnerability in the Pager agent of multi-agent notification feature in Mitsubishi Electric Iconics Digital Solutions GENESIS64 prior to 10.97.3, Mitsubishi Electric GENESIS64 all versions and Mitsubishi Electric MC Works64 all versions allows a local authenticated attacker to make an unauthorized write to arbitrary files, by creating a symbolic link from a file used as a write destination by the services of the affected products to a target file. This could allow the attacker to destroy the file on a PC with the affected products installed, resulting in a denial-of-service (DoS) condition on the PC if the destroyed file is necessary for the operation of the PC.
The exploitability of CVE-2025-0921 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
CVE-2025-0921 presents an accessible attack vector with minimal effort required. Restricting access controls and implementing security updates are critical to reducing exploitation risks.
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
Above is the CVSS Sub-score Breakdown for CVE-2025-0921, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
Below is the Impact Analysis for CVE-2025-0921, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
