It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2021-40843 and fix it if it is affected.\n\nWhat it is: CVE-2021-40843 is a high-severity unsafe deserialization vulnerability in n/a, published on 13 Oct 2021. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-40843 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2021-40843/ (Markdown: https://insights.sbomify.com/CVE-2021-40843/index.md)","id":"CVE-2021-40843","markdown":"https://insights.sbomify.com/CVE-2021-40843/index.md","name":"CVE-2021-40843","record":{"aliases":["GHSA-7c7v-mm4m-x9mj"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Insider Threat Management Server","requires_auth":"low_privilege","summary":"An attacker with local database write access can trigger unsafe deserialization to execute arbitrary code with SYSTEM privileges on the server.","user_interaction":"required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"insider_threat_management_server","vendor":"proofpoint"}],"cvss":{"score":7.3,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"Proofpoint Insider Threat Management Server contains an unsafe deserialization vulnerability in the Web Console.
