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-2021-26608 and fix it if it is affected.\n\nWhat it is: CVE-2021-26608 is a high-severity code injection vulnerability in handysoft HShell.dll, published on 9 Sep 2021. 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-2021-26608 in the wild and no public exploit code.\n\nAffected product: handysoft HShell.dll. 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-2021-26608/ (Markdown: https://insights.sbomify.com/CVE-2021-26608/index.md)","id":"CVE-2021-26608","markdown":"https://insights.sbomify.com/CVE-2021-26608/index.md","name":"CVE-2021-26608","record":{"aliases":["GHSA-744f-76g7-h835"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Handysoft Groupware ActiveX","requires_auth":"none","summary":"Attackers can exploit missing integrity checks in the HShell.dll ActiveX module to download and execute arbitrary files, leading to code execution.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"krcert","cpe":[{"product":"hshell","vendor":"handysoft"}],"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-345","name":"Insufficient Verification of Data Authenticity"},{"id":"CWE-353","name":"Missing Support for Integrity Check"}],"description":"An arbitrary file download and execution vulnerability was found in the HShell.dll of handysoft Co., Ltd groupware ActiveX module.
