Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-43320 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2023-43320/ (Markdown: https://insights.sbomify.com/CVE-2023-43320/index.md)","id":"CVE-2023-43320","markdown":"https://insights.sbomify.com/CVE-2023-43320/index.md","name":"CVE-2023-43320","record":{"aliases":["GHSA-prc6-xmpq-r4g3"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["privilege_escalation","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Proxmox virtualization platform","requires_auth":"low_privilege","summary":"Remote authenticated attackers can escalate privileges by bypassing two-factor authentication in Proxmox VE, Backup Server, and Mail Gateway.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"backup_server","vendor":"proxmox"},{"product":"proxmox_mail_gateway","vendor":"proxmox"},{"product":"virtual_environment","vendor":"proxmox"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"An issue in Proxmox Server Solutions GmbH Proxmox VE v.5.4 thru v.8.0, Proxmox Backup Server v.1.1 thru v.3.0, and Proxmox Mail Gateway v.7.1 thru v.8.0 allows a remote authenticated attacker to escalate privileges via bypassing the two-factor authentication component.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Auth bypass in n/a","id":"CVE-2023-43320","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2023"},"n_packages":0,"n_references":4,"next":{"headline":"File upload in n/a","id":"CVE-2023-43321"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2023-43319"},"products":["n/a"],"published":"2023-09-27","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-11-26","vendors":["n/a"]},"summary":"Remote authenticated attackers can escalate privileges by bypassing two-factor authentication in Proxmox VE, Backup Server, and Mail Gateway.","url":"https://insights.sbomify.com/CVE-2023-43320/"}
