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-2023-20032 in the wild and no public exploit code.\n\nAffected product: Cisco Web Security Appliance. 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-2023-20032/ (Markdown: https://insights.sbomify.com/CVE-2023-20032/index.md)","id":"CVE-2023-20032","markdown":"https://insights.sbomify.com/CVE-2023-20032/index.md","name":"CVE-2023-20032","record":{"aliases":["AZL-13724","CLEANSTART-2026-RA22735","DEBIAN-CVE-2023-20032","UBUNTU-CVE-2023-20032"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"ClamAV scanning library","requires_auth":"none","summary":"Remote attackers can execute arbitrary code or cause denial of service via crafted HFS+ files due to a heap buffer overflow in ClamAV.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"secure_endpoint","vendor":"cisco"},{"product":"secure_endpoint_private_cloud","vendor":"cisco"},{"product":"web_security_appliance","vendor":"cisco"},{"product":"clamav","vendor":"clamav"},{"product":"stormshield_network_security","vendor":"stormshield"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"On Feb 15, 2023, the following vulnerability in the ClamAV scanning library was disclosed:\r\n\r \r A vulnerability in the HFS+ partition file parser of ClamAV versions 1.0.0 and earlier, 0.105.1 and earlier, and 0.103.7 and earlier could allow an unauthenticated, remote attacker to execute arbitrary code.\r\n\r \r This vulnerability is due to a missing buffer size check that may result in a heap buffer overflow write.
