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-2024-23440 and fix it if it is affected.\n\nWhat it is: CVE-2024-23440 is a high-severity vulnerability in VirusBlokAda Vba32 Antivirus, published on 13 Feb 2024. 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-2024-23440 in the wild and no public exploit code.\n\nAffected product: VirusBlokAda Vba32 Antivirus. 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-2024-23440/ (Markdown: https://insights.sbomify.com/CVE-2024-23440/index.md)","id":"CVE-2024-23440","markdown":"https://insights.sbomify.com/CVE-2024-23440/index.md","name":"CVE-2024-23440","record":{"aliases":["GHSA-jr25-xhw2-xwv9"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Windows antivirus driver","requires_auth":"low_privilege","summary":"A local attacker can read arbitrary kernel memory via a vulnerable IOCTL in the Vba32 Antivirus driver, potentially exposing sensitive system data.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Fluid Attacks","cpe":[{"product":"vba32","vendor":"anti-virus"}],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"Vba32 Antivirus v3.36.0 is vulnerable to an Arbitrary Memory Read vulnerability. The 0x22200B IOCTL code of the Vba32m64.sys driver allows to read up to 0x802 of memory from ar arbitrary user-supplied pointer.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Vba32 Antivirus v3.36.0 - Arbitrary Memory Read","id":"CVE-2024-23440","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2024"},"n_packages":0,"n_references":2,"next":{"headline":"Vba32 Antivirus v3.36.0 - Denial of Service (DoS)","id":"CVE-2024-23441"},"packages":[],"prev":{"headline":"Vba32 Antivirus v3.36.0 - Arbitrary Memory Read","id":"CVE-2024-23439"},"products":["Vba32 Antivirus"],"published":"2024-02-13","related":[{"cvss_score":7.1,"headline":"Vba32 Antivirus v3.36.0 - Arbitrary Memory Read","id":"CVE-2024-23439","kev_date_added":null,"published":"2024-02-13"},{"cvss_score":5.5,"headline":"Vba32 Antivirus v3.36.0 - Denial of Service (DoS)","id":"CVE-2024-23441","kev_date_added":null,"published":"2024-01-29"},{"cvss_score":4.3,"headline":"Security feature bypass in n/a","id":"CVE-2012-1461","kev_date_added":null,"published":"2012-03-21"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-05-19","vendors":["VirusBlokAda"]},"summary":"A local attacker can read arbitrary kernel memory via a vulnerable IOCTL in the Vba32 Antivirus driver, potentially exposing sensitive system data.","url":"https://insights.sbomify.com/CVE-2024-23440/"}
