An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2016-0721 in the wild and no public exploit code.\n\nAffected product: Fedoraproject Fedora. 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-2016-0721/ (Markdown: https://insights.sbomify.com/CVE-2016-0721/index.md)","id":"CVE-2016-0721","markdown":"https://insights.sbomify.com/CVE-2016-0721/index.md","name":"CVE-2016-0721","record":{"aliases":["DEBIAN-CVE-2016-0721","GHSA-25mh-8263-4259"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Pacemaker cluster manager","requires_auth":"none","summary":"Attackers can hijack user sessions in the Pacemaker cluster manager's web interface, potentially gaining unauthorized access to cluster management functions.","user_interaction":"required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"pcs","vendor":"clusterlabs"},{"product":"fedora","vendor":"fedoraproject"},{"product":"enterprise_linux","vendor":"redhat"}],"cvss":{"score":8.1,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N","version":"3.0"},"cwes":[{"id":"CWE-384","name":"Session Fixation"}],"description":"Session fixation vulnerability in pcsd in pcs before 0.9.157.","ecosystems":[],"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":"Other in n/a","id":"CVE-2016-0721","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"fedoraproject:fedora","products":["fedoraproject:fedora","redhat:enterprise_linux"],"type":"other","year":"2016"},"n_packages":0,"n_references":8,"next":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2016-0722"},"packages":[],"prev":{"headline":"Cross-site request forgery in n/a","id":"CVE-2016-0720"},"products":["n/a"],"published":"2017-04-21","related":[{"cvss_score":9.8,"headline":"It was discovered that an update for PCS package in RHBA-2023:2151 erratum released as part of Red Hat Enterprise Linux 9.2 failed to includ","id":"CVE-2023-2319","kev_date_added":null,"published":"2023-05-17"},{"cvss_score":8.8,"headline":"Auth bypass in clusterlabs/pcs","id":"CVE-2022-1049","kev_date_added":null,"published":"2022-03-25"},{"cvss_score":8.8,"headline":"Cross-site request forgery in n/a","id":"CVE-2016-0720","kev_date_added":null,"published":"2017-04-21"},{"cvss_score":7.8,"headline":"Privilege escalation in ClusterLabs/pcs","id":"CVE-2022-2735","kev_date_added":null,"published":"2022-09-06"},{"cvss_score":6.1,"headline":"Cross-site scripting in pcs","id":"CVE-2017-2661","kev_date_added":null,"published":"2018-03-12"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"Attackers can hijack user sessions in the Pacemaker cluster manager's web interface, potentially gaining unauthorized access to cluster management functions.","url":"https://insights.sbomify.com/CVE-2016-0721/"}
