It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-90457 in the wild and no public exploit code.\n\nAffected product: CISA Malcolm. 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-2026-90457/ (Markdown: https://insights.sbomify.com/CVE-2026-90457/index.md)","id":"CVE-2026-90457","markdown":"https://insights.sbomify.com/CVE-2026-90457/index.md","name":"CVE-2026-90457","record":{"aliases":["GHSA-r5jf-jfmr-83g3"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["account_takeover","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Malcolm network monitoring","requires_auth":"none","summary":"Weak password hashing and insecure file permissions allow local attackers to recover administrative credentials via offline computation.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-916","name":"Use of Password Hash With Insufficient Computational Effort"}],"description":"The administrative password is hashed using a comparatively weak, fast algorithm for the credential store backing one authentication path, and the file containing that hash is written with permissions allowing it to be read by any local user.
