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-2016-3656 in the wild and no public exploit code.\n\nAffected product: Paloaltonetworks Pan-Os. 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-2016-3656/ (Markdown: https://insights.sbomify.com/CVE-2016-3656/index.md)","id":"CVE-2016-3656","markdown":"https://insights.sbomify.com/CVE-2016-3656/index.md","name":"CVE-2016-3656","record":{"aliases":["GHSA-g92w-qq3j-8px4"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Palo Alto PAN-OS","requires_auth":"none","summary":"Remote attackers can crash the GlobalProtect Portal service via crafted requests, requiring administrators to upgrade PAN-OS.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"pan-os","vendor":"paloaltonetworks"}],"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":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"The GlobalProtect Portal in Palo Alto Networks PAN-OS before 5.0.18, 6.0.x before 6.0.13, 6.1.x before 6.1.10, and 7.0.x before 7.0.5H2 allows remote attackers to cause a denial of service (service crash) via a crafted request.","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-2016-3656","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"paloaltonetworks:pan-os","products":["paloaltonetworks:pan-os"],"type":"denial_of_service","year":"2016"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in n/a","id":"CVE-2016-3657"},"packages":[],"prev":{"headline":"Command injection in n/a","id":"CVE-2016-3655"},"products":["n/a"],"published":"2016-04-12","related":[{"cvss_score":10,"headline":"Palo Alto Networks PAN-OS Command Injection","id":"CVE-2024-3400","kev_date_added":"2024-04-12","published":"2024-04-12"},{"cvss_score":10,"headline":"Palo Alto Networks PAN-OS Authentication Bypass","id":"CVE-2020-2021","kev_date_added":"2022-03-25","published":"2020-06-29"},{"cvss_score":9.8,"headline":"Palo Alto Networks PAN-OS Remote Code Execution","id":"CVE-2017-15944","kev_date_added":"2022-08-18","published":"2017-12-11"},{"cvss_score":9.3,"headline":"Palo Alto Networks PAN-OS Out-of-bounds Write","id":"CVE-2026-0300","kev_date_added":"2026-05-06","published":"2026-05-06"},{"cvss_score":9.3,"headline":"Palo Alto Networks PAN-OS Management Interface Authentication Bypass","id":"CVE-2024-0012","kev_date_added":"2024-11-18","published":"2024-11-18"},{"cvss_score":9.2,"headline":"PHP Memory Corruption","id":"CVE-2026-109618","kev_date_added":"2026-10-26","published":"2026-10-21"},{"cvss_score":9.2,"headline":"PHP Stale Internal Request-State","id":"CVE-2026-109619","kev_date_added":"2026-10-26","published":"2026-10-21"}],"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":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can crash the GlobalProtect Portal service via crafted requests, requiring administrators to upgrade PAN-OS.","url":"https://insights.sbomify.com/CVE-2016-3656/"}
