An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-5241 in the wild and no public exploit code.\n\nAffected product: Mitsubishi Electric Corporation MELSEC iQ-F Series FX5-CCLGN-MS. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2025-5241/ (Markdown: https://insights.sbomify.com/CVE-2025-5241/index.md)","id":"CVE-2025-5241","markdown":"https://insights.sbomify.com/CVE-2025-5241/index.md","name":"CVE-2025-5241","record":{"aliases":["GHSA-7w8q-8495-mwhj"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Mitsubishi PLC","requires_auth":"none","summary":"Remote attackers can lock out legitimate users from Mitsubishi MELSEC iQ-F PLCs by triggering the account lockout mechanism with repeated failed login attempts.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Mitsubishi","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-645","name":"Overly Restrictive Account Lockout Mechanism"}],"description":"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.
