CVE-2025-5241 Vulnerability Summary

CVE-2025-5241: Overly Restrictive Account Lockout Mechanism vulnerability in Mitsubishi Electric Corporation MELSEC iQ-F Series allows a remote unauthenticated attacker to lockout legitimate users for a certain period by repeatedly attempting to login with incorrect passwords. The legitimate users will be unable to login until a certain period has passed after the lockout or until the product is reset.

Assessing the Risk of CVE-2025-5241

Access Complexity Graph

The exploitability of CVE-2025-5241 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).

Exploitability Analysis for CVE-2025-5241

With low attack complexity and no required privileges, CVE-2025-5241 is an easy target for cybercriminals. Organizations should prioritize immediate mitigation measures to prevent unauthorized access and data breaches.

Understanding AC and PR

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.

CVSS Score Breakdown Chart

Above is the CVSS Sub-score Breakdown for CVE-2025-5241, 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.

CWE Common Weakness Enumeration

CWE-645

CAPEC Common Attack Pattern Enumeration and Classification

  • Inducing Account Lockout CAPEC-2 An attacker leverages the security functionality of the system aimed at thwarting potential attacks to launch a denial of service attack against a legitimate system user. Many systems, for instance, implement a password throttling mechanism that locks an account after a certain number of incorrect log in attempts. An attacker can leverage this throttling mechanism to lock a legitimate user out of their own account. The weakness that is being leveraged by an attacker is the very security feature that has been put in place to counteract attacks.
