It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-36724 and fix it if it is affected.\n\nWhat it is: CVE-2021-36724 is a medium-severity memory corruption vulnerability in ForeScout eServices / eNvoice, published on 29 Dec 2021. 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-2021-36724 in the wild and no public exploit code.\n\nAffected product: ForeScout eServices / eNvoice. 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-2021-36724/ (Markdown: https://insights.sbomify.com/CVE-2021-36724/index.md)","id":"CVE-2021-36724","markdown":"https://insights.sbomify.com/CVE-2021-36724/index.md","name":"CVE-2021-36724","record":{"aliases":["GHSA-cvrj-cr4m-fg2f"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"SecureConnector service","requires_auth":"low_privilege","summary":"A local low-privileged user can crash the SecureConnector service by writing excessive characters to the installation path, causing a buffer overflow.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"INCD","cpe":[{"product":"secureconnector","vendor":"forescout"}],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"ForeScout - SecureConnector Local Service DoS - A low privilaged user which doesn't have permissions to shutdown the secure connector service writes a large amount of characters in the installationPath.
