It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-30156 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- ceph (Bitnami): affected all versions; fixed in 19.2.6, 20.2.4\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-2025-30156/ (Markdown: https://insights.sbomify.com/CVE-2025-30156/index.md)","id":"CVE-2025-30156","markdown":"https://insights.sbomify.com/CVE-2025-30156/index.md","name":"CVE-2025-30156","record":{"aliases":["AZL-98039","BIT-ceph-2025-30156","DEBIAN-CVE-2025-30156","ECHO-5896-cc77-aa09","GHSA-7q3q-3975-qw3q","MINI-7cjm-7pr8-cmr6","MINI-jqvh-r38x-qgc2","UBUNTU-CVE-2025-30156"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["privilege_escalation","account_takeover"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Ceph distributed storage","requires_auth":"low_privilege","summary":"Weak AES-CBC implementation in CephX allows attackers to forge credentials and escalate privileges to cluster-wide access.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":8.9,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:L","version":"3.1"},"cwes":[{"id":"CWE-327","name":"Use of a Broken or Risky Cryptographic Algorithm"}],"description":"Ceph is an open-source distributed storage platform providing object, block, and file storage. In versions prior to 20.2.4 and 19.2.6, the CephX authentication protocol encrypts tickets with AES-128-CBC in an unauthenticated mode that uses a hard-coded initialization vector and no message authentication, allowing an attacker to forge credentials and gain cluster-wide access. Because the ciphertext is malleable and the monitor will encrypt attacker-chosen entity names, an attacker holding one low-privilege key and able to observe CephX traffic can use the monitor as an encryption oracle and splice ciphertext blocks into valid tickets for privileged entities such as Manager, MDS, and OSD. The same lack of authentication also lets an attacker with CephX permissions escalate privileges by flipping a single bit in a service ticket to set its allow_all field to true. This issue is fixed in versions 20.2.4 and 19.2.6.","ecosystems":["Bitnami"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Ceph: AES-CBC misuse in CephX and RADOSGW enables authentication bypass and credential forgery","id":"CVE-2025-30156","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"weak_cryptography","year":"2025"},"n_packages":1,"n_references":3,"next":{"headline":"Envoy crashes when HTTP ext_proc processes local replies","id":"CVE-2025-30157"},"packages":[{"ecosystem":"Bitnami","fixed":["19.2.6","20.2.4"],"introduced":["0","20.0.0"],"last_affected":[],"package":"ceph","purl":"pkg:bitnami/ceph","source":"BIT-ceph-2025-30156"}],"prev":{"headline":"Tuleap does not enforce read permissions on parent trackers in the REST API","id":"CVE-2025-30155"},"products":["ceph"],"published":"2026-08-27","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-09-01","vendors":["ceph"]},"summary":"Weak AES-CBC implementation in CephX allows attackers to forge credentials and escalate privileges to cluster-wide access.","url":"https://insights.sbomify.com/CVE-2025-30156/"}
