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-2018-6320 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-2018-6320/ (Markdown: https://insights.sbomify.com/CVE-2018-6320/index.md)","id":"CVE-2018-6320","markdown":"https://insights.sbomify.com/CVE-2018-6320/index.md","name":"CVE-2018-6320","record":{"aliases":["GHSA-86rc-v7r8-8fwp"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Pulse Secure PCS/PPS","requires_auth":"none","summary":"Attackers can bypass security controls by sending unvalidated Host headers to Pulse Secure PCS and PPS login interfaces.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"connect_secure","vendor":"ivanti"},{"product":"pulse_connect_secure","vendor":"pulsesecure"},{"product":"pulse_policy_secure","vendor":"pulsesecure"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"A vulnerability has been discovered in login.cgi in Pulse Secure Pulse Connect Secure (PCS) 8.1RX before 8.1R12 and 8.3RX before 8.3R2 and Pulse Policy Secure (PPS) 5.2RX before 5.2R9 and 5.4RX before 5.4R2 wherein an http(s) Host header received from the browser is trusted without validation.","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":"Other in n/a","id":"CVE-2018-6320","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"ivanti:connect_secure","products":["ivanti:connect_secure","pulsesecure:pulse_connect_secure"],"type":"other","year":"2018"},"n_packages":0,"n_references":1,"next":{"headline":"Privilege escalation in n/a","id":"CVE-2018-6321"},"packages":[],"prev":{"headline":"Null dereference in n/a","id":"CVE-2018-6319"},"products":["n/a"],"published":"2018-09-06","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":"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 bypass security controls by sending unvalidated Host headers to Pulse Secure PCS and PPS login interfaces.","url":"https://insights.sbomify.com/CVE-2018-6320/"}
