CVE-2025-2399: Improper Validation of Specified Index, Position, or Offset in Input vulnerability in Mitsubishi Electric CNC M800V Series M800VW and M800VS, M80V Series M80V and M80VW, M800 Series M800W and M800S, M80 Series M80 and M80W, E80 Series E80, C80 Series C80, M700V Series M750VW, M720VW, 730VW, M720VS, M730VS, and M750VS, M70V Series M70V, E70 Series E70, and Software Tools NC Trainer2 and NC Trainer2 plus allows a remote attacker to cause an out-of-bounds read, resulting in a denial-of-service condition by sending specially crafted packets to TCP port 683.
The exploitability of CVE-2025-2399 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-2025-2399 presents a challenge to exploit due to its high attack complexity, but the absence of privilege requirements still makes it a viable target for skilled attackers. A thorough security review is advised.
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-2025-2399, 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-2025-2399, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
