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-2024-40720 and fix it if it is affected.\n\nWhat it is: CVE-2024-40720 is a high-severity command injection vulnerability in CHANGING Information Technology TCBServiSign Windows Version, published on 2 Aug 2024. 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-2024-40720 in the wild and no public exploit code.\n\nAffected product: CHANGING Information Technology TCBServiSign Windows Version. 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-2024-40720/ (Markdown: https://insights.sbomify.com/CVE-2024-40720/index.md)","id":"CVE-2024-40720","markdown":"https://insights.sbomify.com/CVE-2024-40720/index.md","name":"CVE-2024-40720","record":{"aliases":["GHSA-whp4-jh65-8472"],"analysis":{"component_type":"desktop_application","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"TCBServiSign Windows","requires_auth":"none","summary":"Remote attackers can execute arbitrary commands by modifying the registry via a spoofed website due to improper input validation in TCBServiSign.","user_interaction":"required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"twcert","cpe":[{"product":"tcb_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-20","name":"Improper Input Validation"}],"description":"The specific API in TCBServiSign Windows Version from CHANGING Information Technology does not properly validate server-side input.
