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-2016-4786 in the wild and no public exploit code.\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-2016-4786/ (Markdown: https://insights.sbomify.com/CVE-2016-4786/index.md)","id":"CVE-2016-4786","markdown":"https://insights.sbomify.com/CVE-2016-4786/index.md","name":"CVE-2016-4786","record":{"aliases":["GHSA-8w55-xhm5-jh9r"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Pulse Connect Secure","requires_auth":"none","summary":"Remote attackers can cause a denial of service via CPU consumption in Pulse Connect Secure appliances, requiring an upgrade to mitigate.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"connect_secure","vendor":"ivanti"},{"product":"pulse_connect_secure","vendor":"pulsesecure"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[],"description":"Pulse Connect Secure (PCS) 8.2 before 8.2r1, 8.1 before 8.1r3, 8.0 before 8.0r11, and 7.4 before 7.4r13.4 allow remote attackers to cause a denial of service (CPU consumption) via unspecified vectors.","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":"Denial of service in n/a","id":"CVE-2016-4786","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"ivanti:connect_secure","products":["ivanti:connect_secure","pulsesecure:pulse_connect_secure"],"type":"denial_of_service","year":"2016"},"n_packages":0,"n_references":2,"next":{"headline":"Information disclosure in n/a","id":"CVE-2016-4787"},"packages":[],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2016-4785"},"products":["n/a"],"published":"2016-05-26","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 Collaboration Suite Buffer Overflow","id":"CVE-2021-22894","kev_date_added":"2021-11-03","published":"2021-05-27"},{"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":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can cause a denial of service via CPU consumption in Pulse Connect Secure appliances, requiring an upgrade to mitigate.","url":"https://insights.sbomify.com/CVE-2016-4786/"}
