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-2023-40256 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-2023-40256/ (Markdown: https://insights.sbomify.com/CVE-2023-40256/index.md)","id":"CVE-2023-40256","markdown":"https://insights.sbomify.com/CVE-2023-40256/index.md","name":"CVE-2023-40256","record":{"aliases":["GHSA-p3h6-32q9-xwh5"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","data_modify","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Veritas NetBackup Snapshot Manager","requires_auth":"none","summary":"Untrusted clients can manipulate backup and restore job messages due to improper RabbitMQ certificate validation, affecting confidentiality, integrity, and availability.","user_interaction":"not_required","vuln_class":"misconfiguration"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"netbackup_snapshot_manager","vendor":"veritas"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AC:L/AV:N/A:H/C:H/I:H/PR:N/S:U/UI:N","version":"3.1"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"}],"description":"A vulnerability was discovered in Veritas NetBackup Snapshot Manager before 10.2.0.1 that allowed untrusted clients to interact with the RabbitMQ service. This was caused by improper validation of the client certificate due to misconfiguration of the RabbitMQ service. Exploiting this impacts the confidentiality and integrity of messages controlling the backup and restore jobs, and could result in the service becoming unavailable. This impacts only the jobs controlling the backup and restore activities, and does not allow access to (or deletion of) the backup snapshot data itself. This vulnerability is confined to the NetBackup Snapshot Manager feature and does not impact the RabbitMQ instance on the NetBackup primary servers.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Misconfiguration in n/a","id":"CVE-2023-40256","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"misconfiguration","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Auth bypass in n/a","id":"CVE-2023-40260"},"packages":[],"prev":{"headline":"Supply chain in Genian NAC Suite V5.0","id":"CVE-2023-40254"},"products":["n/a"],"published":"2023-08-11","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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-10-10","vendors":["n/a"]},"summary":"Untrusted clients can manipulate backup and restore job messages due to improper RabbitMQ certificate validation, affecting confidentiality, integrity, and availability.","url":"https://insights.sbomify.com/CVE-2023-40256/"}
