Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-44052 in the wild and no public exploit code.\n\nAffected product: Qnap Qts. 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-2021-44052/ (Markdown: https://insights.sbomify.com/CVE-2021-44052/index.md)","id":"CVE-2021-44052","markdown":"https://insights.sbomify.com/CVE-2021-44052/index.md","name":"CVE-2021-44052","record":{"aliases":["GHSA-q4mx-gr8m-q3rr"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"QNAP NAS OS","requires_auth":"low_privilege","summary":"Remote attackers can traverse the file system to read or overwrite unintended files on QNAP NAS devices due to improper link resolution.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"qnap","cpe":[{"product":"qts","vendor":"qnap"},{"product":"quts_hero","vendor":"qnap"},{"product":"qutscloud","vendor":"qnap"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-59","name":"Improper Link Resolution Before File Access"}],"description":"An improper link resolution before file access ('Link Following') vulnerability has been reported to affect QNAP device running QuTScloud, QuTS hero, and QTS.
