Perceptive Document Filters, published on 26 Apr 2018. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2018-3844 in the wild and no public exploit code.\n\nAffected product: Hyland Software, Inc. Perceptive Document Filters. 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-2018-3844/ (Markdown: https://insights.sbomify.com/CVE-2018-3844/index.md)","id":"CVE-2018-3844","markdown":"https://insights.sbomify.com/CVE-2018-3844/index.md","name":"CVE-2018-3844","record":{"aliases":["GHSA-mxxv-2m94-pqj6"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Document Filters library","requires_auth":"none","summary":"A crafted DOCX document triggers a use-after-free in Hyland Perceptive Document Filters, allowing attackers to execute arbitrary code.","user_interaction":"required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"talos","cpe":[{"product":"perceptive_document_filters","vendor":"hyland"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"In Hyland Perceptive Document Filters 11.4.0.2647 - x86/x64 Windows/Linux, a crafted DOCX document can lead to a use-after-free resulting in direct code execution.","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":"Use after free in Perceptive Document Filters","id":"CVE-2018-3844","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2018"},"n_packages":0,"n_references":2,"next":{"headline":"Use after free in Perceptive Document Filters","id":"CVE-2018-3845"},"packages":[],"prev":{"headline":"Memory corruption in Foxit","id":"CVE-2018-3843"},"products":["Perceptive Document Filters"],"published":"2018-04-26","related":[{"cvss_score":8.8,"headline":"Use after free in Perceptive Document Filters","id":"CVE-2018-3845","kev_date_added":null,"published":"2018-04-26"},{"cvss_score":8.8,"headline":"Memory corruption in Perceptive Document Filters","id":"CVE-2018-3851","kev_date_added":null,"published":"2018-04-26"},{"cvss_score":8.8,"headline":"Use after free in Perceptive Document Filters","id":"CVE-2018-3855","kev_date_added":null,"published":"2018-04-26"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-17","vendors":["Hyland Software, Inc."]},"summary":"A crafted DOCX document triggers a use-after-free in Hyland Perceptive Document Filters, allowing attackers to execute arbitrary code.","url":"https://insights.sbomify.com/CVE-2018-3844/"}
