Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-1518 in the wild and no public exploit code.\n\nAffected product: Cisco Firepower Threat Defense Software. 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-2021-1518/ (Markdown: https://insights.sbomify.com/CVE-2021-1518/index.md)","id":"CVE-2021-1518","markdown":"https://insights.sbomify.com/CVE-2021-1518/index.md","name":"CVE-2021-1518","record":{"aliases":["GHSA-jrp9-wjr5-77p4"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Firepower Device Manager","requires_auth":"low_privilege","summary":"Authenticated attackers can execute arbitrary code on Cisco Firepower Device Manager via crafted REST API requests due to insufficient input sanitization.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"firepower_device_manager_on-box","vendor":"cisco"}],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"A vulnerability in the REST API of Cisco Firepower Device Manager (FDM) On-Box Software could allow an authenticated, remote attacker to execute arbitrary code on the underlying operating system of an affected device.
