HBS 3 Hybrid Backup Sync, published on 7 Mar 2025. 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-2024-53695 in the wild and no public exploit code.\n\nAffected product: QNAP Systems Inc. HBS 3 Hybrid Backup Sync. 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-2024-53695/ (Markdown: https://insights.sbomify.com/CVE-2024-53695/index.md)","id":"CVE-2024-53695","markdown":"https://insights.sbomify.com/CVE-2024-53695/index.md","name":"CVE-2024-53695","record":{"aliases":["GHSA-56j5-vwwf-v97g"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"QNAP backup software","requires_auth":"none","summary":"Remote attackers can exploit a buffer overflow in QNAP HBS 3 to modify memory, execute code, or crash processes.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"qnap","cpe":[{"product":"hybrid_backup_sync","vendor":"qnap"}],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-121","name":"Stack-based Buffer Overflow"},{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"A buffer overflow vulnerability has been reported to affect HBS 3 Hybrid Backup Sync.
