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-2021-26622 and fix it if it is affected.\n\nWhat it is: CVE-2021-26622 is a critical code injection vulnerability in Genians Co., Ltd Genian NAC Suite V4.0, published on 25 Mar 2022. 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-2021-26622 in the wild and no public exploit code.\n\nAffected product: Genians Co., Ltd Genian NAC Suite V4.0. 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-2021-26622/ (Markdown: https://insights.sbomify.com/CVE-2021-26622/index.md)","id":"CVE-2021-26622","markdown":"https://insights.sbomify.com/CVE-2021-26622/index.md","name":"CVE-2021-26622","record":{"aliases":["GHSA-q8rg-c9v7-62r5"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Network Access Control","requires_auth":"none","summary":"Remote attackers can execute arbitrary code with SYSTEM privileges on Genian NAC nodes via Server-Side Template Injection and insufficient validation.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"krcert","cpe":[{"product":"genian_nac","vendor":"genians"}],"cvss":{"score":9.6,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"},{"id":"CWE-20","name":"Improper Input Validation"}],"description":"An remote code execution vulnerability due to SSTI vulnerability and insufficient file name parameter validation was discovered in Genian NAC.
