Any signed-in user can exploit it over the network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2024-42453 and fix it if it is affected.\n\nWhat it is: CVE-2024-42453 is a high-severity missing authorization vulnerability in Veeam Backup \u0026 Replication, published on 4 Dec 2024. Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-42453 in the wild and no public exploit code.\n\nAffected product: Veeam Backup \u0026 Replication. 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-2024-42453/ (Markdown: https://insights.sbomify.com/CVE-2024-42453/index.md)","id":"CVE-2024-42453","markdown":"https://insights.sbomify.com/CVE-2024-42453/index.md","name":"CVE-2024-42453","record":{"aliases":["GHSA-78w4-wf5r-hgxq"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_modify","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Backup \u0026 Replication","requires_auth":"low_privilege","summary":"Low-privileged users can modify virtual infrastructure configurations, causing denial of service and data integrity issues due to improper permission checks.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"veeam_backup_\\\u0026_replication","vendor":"veeam"}],"cvss":{"score":7.4,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:L","version":"3.0"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"A vulnerability Veeam Backup \u0026 Replication allows low-privileged users to control and modify configurations on connected virtual infrastructure hosts.
