An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-22857 and fix it if it is affected.\n\nWhat it is: CVE-2021-22857 is a high-severity path traversal vulnerability in ChanGate EnterPrise Co., Ltd property management system, published on 17 Feb 2021. An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-22857 in the wild and no public exploit code.\n\nAffected product: ChanGate EnterPrise Co., Ltd property management system. 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-2021-22857/ (Markdown: https://insights.sbomify.com/CVE-2021-22857/index.md)","id":"CVE-2021-22857","markdown":"https://insights.sbomify.com/CVE-2021-22857/index.md","name":"CVE-2021-22857","record":{"aliases":["GHSA-6m76-9vmm-c44v"],"analysis":{"component_type":"web_application","fix_type":"no_fix_stated","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Property management system","requires_auth":"none","summary":"Attackers can exploit a directory traversal flaw in the download function to arbitrarily read system files from the property management system.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"twcert","cpe":[{"product":"changjia_property_management_system","vendor":"changjia_property_management_system_project"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"The CGE page with download function contains a Directory Traversal vulnerability.
