Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2021-22894 in the wild since at least 3 Nov 2021.\n\nAffected product: Ivanti Connect Secure. 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-2021-22894/ (Markdown: https://insights.sbomify.com/CVE-2021-22894/index.md)","id":"CVE-2021-22894","markdown":"https://insights.sbomify.com/CVE-2021-22894/index.md","name":"CVE-2021-22894","record":{"aliases":["GHSA-2f6h-jr2m-2vpj"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Pulse Connect Secure","requires_auth":"low_privilege","summary":"Remote authenticated attackers can execute arbitrary code as root via a buffer overflow in Pulse Connect Secure meeting rooms.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"connect_secure","vendor":"ivanti"}],"cvss":{"score":8.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"},{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"A buffer overflow vulnerability exists in Pulse Connect Secure before 9.1R11.4 allows a remote authenticated attacker to execute arbitrary code as the root user via maliciously crafted meeting room.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"exploited"},"has_fix":null,"headline":"Ivanti Pulse Connect Secure Collaboration Suite Buffer Overflow","id":"CVE-2021-22894","indexable":true,"kev":{"dateAdded":"2021-11-03","dueDate":"2022-05-03","knownRansomwareCampaignUse":"Unknown","product":"Pulse Connect Secure","requiredAction":"Apply updates per vendor instructions.","vendorProject":"Ivanti","vulnerabilityName":"Ivanti Pulse Connect Secure Collaboration Suite Buffer Overflow Vulnerability"},"kind":"cve","links":{"ecosystem":null,"product":"ivanti:connect_secure","products":["ivanti:connect_secure"],"type":"memory_corruption","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Security feature bypass in Nextcloud Desktop Client","id":"CVE-2021-22895"},"packages":[],"prev":{"headline":"Ivanti Pulse Connect Secure Use-After-Free","id":"CVE-2021-22893"},"products":["Pulse Connect Secure"],"published":"2021-05-27","related":[{"cvss_score":10,"headline":"Ivanti Pulse Connect Secure Use-After-Free","id":"CVE-2021-22893","kev_date_added":"2021-11-03","published":"2021-04-23"},{"cvss_score":9.9,"headline":"Ivanti Pulse Connect Secure Arbitrary File Read","id":"CVE-2019-11510","kev_date_added":"2021-11-03","published":"2019-05-08"},{"cvss_score":9.1,"headline":"Ivanti Connect Secure and Policy Secure Command Injection","id":"CVE-2024-21887","kev_date_added":"2024-01-10","published":"2024-01-12"},{"cvss_score":9,"headline":"Ivanti Connect Secure, Policy Secure, and ZTA Gateways Stack-Based Buffer Overflow","id":"CVE-2025-22457","kev_date_added":"2025-04-04","published":"2025-04-03"},{"cvss_score":9,"headline":"Ivanti Connect Secure, Policy Secure, and ZTA Gateways Stack-Based Buffer Overflow","id":"CVE-2025-0282","kev_date_added":"2025-01-08","published":"2025-01-08"},{"cvss_score":8.8,"headline":"Ivanti Pulse Connect Secure Command Injection","id":"CVE-2021-22899","kev_date_added":"2021-11-03","published":"2021-05-27"}],"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":"open","licence":"CC0 1.0","name":"CISA KEV"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"active","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-10-21","vendors":["n/a"]},"summary":"Remote authenticated attackers can execute arbitrary code as root via a buffer overflow in Pulse Connect Secure meeting rooms.","url":"https://insights.sbomify.com/CVE-2021-22894/"}
