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-2021-34773 in the wild and no public exploit code.\n\nAffected product: Cisco Unified Communications Manager. 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-2021-34773/ (Markdown: https://insights.sbomify.com/CVE-2021-34773/index.md)","id":"CVE-2021-34773","markdown":"https://insights.sbomify.com/CVE-2021-34773/index.md","name":"CVE-2021-34773","record":{"aliases":["GHSA-rj22-gp23-c66j"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Unified Communications Manager","requires_auth":"none","summary":"An attacker can trick users into performing unauthorized actions like modifying configuration or deleting accounts via CSRF in Cisco Unified Communications Manager.","user_interaction":"required","vuln_class":"csrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"unified_communications_manager","vendor":"cisco"},{"product":"unified_communications_manager_im_and_presence_service","vendor":"cisco"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-352","name":"Cross-Site Request Forgery"}],"description":"A vulnerability in the web-based management interface of Cisco Unified Communications Manager (Unified CM), Cisco Unified Communications Manager Session Management Edition (Unified CM SME), and Cisco Unified Communications Manager IM \u0026amp; Presence Service (Unified CM IM\u0026amp;P) could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack on an affected device. This vulnerability is due to insufficient CSRF protections for the web-based management interface on an affected device. An attacker could exploit this vulnerability by persuading a user of the interface to click a malicious link. A successful exploit could allow the attacker to perform arbitrary actions with the privilege level of the targeted user. These actions could include modifying the device configuration and deleting (but not creating) user accounts.","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":"Cisco Unified Communications Products Cross-Site Request Forgery Vulnerability","id":"CVE-2021-34773","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:unified_communications_manager","products":["cisco:unified_communications_manager"],"type":"csrf","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco Common Services Platform Collector Information Disclosure Vulnerability","id":"CVE-2021-34774"},"packages":[],"prev":{"headline":"Cisco Orbital Open Redirect Vulnerability","id":"CVE-2021-34772"},"products":["Cisco Unified Communications Manager"],"published":"2021-11-04","related":[{"cvss_score":8.6,"headline":"Cisco Unified Communications Manager Server-Side Request Forgery (SSRF)","id":"CVE-2026-20230","kev_date_added":"2026-06-25","published":"2026-06-03"},{"cvss_score":8.2,"headline":"Cisco Unified Communications Products Code Injection","id":"CVE-2026-20045","kev_date_added":"2026-01-21","published":"2026-01-21"},{"cvss_score":10,"headline":"Cisco Unified Communications Manager Static SSH Credentials Vulnerability","id":"CVE-2025-20309","kev_date_added":null,"published":"2025-07-02"},{"cvss_score":10,"headline":"Information disclosure in n/a","id":"CVE-2011-1643","kev_date_added":null,"published":"2011-08-29"},{"cvss_score":9.9,"headline":"Deserialization in Cisco Packaged Contact Center Enterprise","id":"CVE-2024-20253","kev_date_added":null,"published":"2024-01-26"},{"cvss_score":9,"headline":"Information disclosure in n/a","id":"CVE-2009-0632","kev_date_added":null,"published":"2009-03-12"},{"cvss_score":8.8,"headline":"SQL injection in Cisco Unified Communications Manager","id":"CVE-2017-6757","kev_date_added":null,"published":"2017-08-07"}],"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":"partial"},"state":"PUBLISHED","updated":"2024-11-07","vendors":["Cisco"]},"summary":"An attacker can trick users into performing unauthorized actions like modifying configuration or deleting accounts via CSRF in Cisco Unified Communications Manager.","url":"https://insights.sbomify.com/CVE-2021-34773/"}
