Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-21545 in the wild and no public exploit code.\n\nAffected product: Proxmox libpve-common-perl (Promox Mail Gateway 8). 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-2024-21545/ (Markdown: https://insights.sbomify.com/CVE-2024-21545/index.md)","id":"CVE-2024-21545","markdown":"https://insights.sbomify.com/CVE-2024-21545/index.md","name":"CVE-2024-21545","record":{"aliases":[],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Proxmox VE","requires_auth":"low_privilege","summary":"Authenticated attackers with audit or monitor privileges can read arbitrary host files via API, potentially leading to system compromise.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"snyk","cpe":[],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-73","name":"External Control of File Name or Path"}],"description":"Proxmox Virtual Environment is an open-source server management platform for enterprise virtualization. Insufficient safeguards against malicious API response values allow authenticated attackers with 'Sys.Audit' or 'VM.Monitor' privileges to download arbitrary host files via the API.\nWhen handling the result from a request handler before returning it to the user, the handle_api2_request function will check for the ‘download’ or ‘data’-\u003e’download’ objects inside the request handler call response object. If present, handle_api2_request will read a local file defined by this object and return it to the user.\nTwo endpoints were identified which can control the object returned by a request handler sufficiently that the ’download’ object is defined and user controlled. This results in arbitrary file read.\nThe privileges of this file read can result in full compromise of the system by various impacts such as disclosing sensitive files allowing for privileged session forgery.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2025-11-30","github_poc":1,"max_poc_stars":1,"metasploit":0,"nuclei":0,"refs":[{"date":"2025-11-30T22:23:13Z","kind":"github_poc","ref":"https://github.com/SpiralBL0CK/CVE-2024-21545-PoC","stars":1,"title":"Proxmox VE Arbitrary File Read -\u003e Full System Compromise .
