An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2022-46306 and fix it if it is affected.\n\nWhat it is: CVE-2022-46306 is a high-severity path traversal vulnerability in ChangingTec ServiSign, published on 3 Jan 2023. 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-2022-46306 in the wild and no public exploit code.\n\nAffected product: ChangingTec ServiSign. 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-2022-46306/ (Markdown: https://insights.sbomify.com/CVE-2022-46306/index.md)","id":"CVE-2022-46306","markdown":"https://insights.sbomify.com/CVE-2022-46306/index.md","name":"CVE-2022-46306","record":{"aliases":["GHSA-pjx5-jjh7-w9hw"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"ServiSign component","requires_auth":"none","summary":"An unauthenticated attacker can trick a user into visiting a malicious site to load arbitrary DLLs via path traversal, enabling code execution and service disruption.","user_interaction":"required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"twcert","cpe":[{"product":"servisign","vendor":"changingtec"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"ChangingTec ServiSign component has a path traversal vulnerability due to insufficient filtering for special characters in the DLL file path.
