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-2023-20264 in the wild and no public exploit code.\n\nAffected product: Cisco Adaptive Security Appliance Software. 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-2023-20264/ (Markdown: https://insights.sbomify.com/CVE-2023-20264/index.md)","id":"CVE-2023-20264","markdown":"https://insights.sbomify.com/CVE-2023-20264/index.md","name":"CVE-2023-20264","record":{"aliases":["GHSA-3gjh-276x-542v"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["account_takeover","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco ASA/FTD VPN","requires_auth":"none","summary":"An attacker can intercept SAML assertions via a modified login URL to hijack remote access VPN sessions and gain network access.","user_interaction":"required","vuln_class":"open_redirect"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"adaptive_security_appliance_software","vendor":"cisco"},{"product":"secure_firewall_threat_defense","vendor":"cisco"}],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-601","name":"URL Redirection to Untrusted Site"}],"description":"A vulnerability in the implementation of Security Assertion Markup Language (SAML) 2.0 single sign-on (SSO) for remote access VPN in Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to intercept the SAML assertion of a user who is authenticating to a remote access VPN session. This vulnerability is due to insufficient validation of the login URL. An attacker could exploit this vulnerability by persuading a user to access a site that is under the control of the attacker, allowing the attacker to modify the login URL. A successful exploit could allow the attacker to intercept a successful SAML assertion and use that assertion to establish a remote access VPN session toward the affected device with the identity and permissions of the hijacked user, resulting in access to the protected network.","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":"Open redirect in Cisco Adaptive Security Appliance (ASA) Software","id":"CVE-2023-20264","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:adaptive_security_appliance_software","products":["cisco:adaptive_security_appliance_software","cisco:secure_firewall_threat_defense"],"type":"open_redirect","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Cross-site scripting in Cisco IP Phones with Multiplatform Firmware","id":"CVE-2023-20265"},"packages":[],"prev":{"headline":"Open redirect in Cisco HyperFlex HX Data Platform","id":"CVE-2023-20263"},"products":["Cisco Adaptive Security Appliance (ASA) Software","Cisco Firepower Threat Defense Software"],"published":"2023-11-01","related":[{"cvss_score":9.9,"headline":"Cisco Secure Firewall Adaptive Security Appliance (ASA) and Secure Firewall Threat Defense (FTD) Buffer Overflow","id":"CVE-2025-20333","kev_date_added":"2025-09-25","published":"2025-09-25"},{"cvss_score":8.8,"headline":"Cisco Adaptive Security Appliance (ASA) SNMP Buffer Overflow","id":"CVE-2016-6366","kev_date_added":"2022-05-24","published":"2016-08-18"},{"cvss_score":8.6,"headline":"Cisco Secure Firewall Adaptive Security Appliance (ASA) and Secure Firewall Threat Defense (FTD) Heap Inspection","id":"CVE-2026-20349","kev_date_added":"2026-08-11","published":"2026-08-11"},{"cvss_score":8.6,"headline":"Cisco ASA and FTD Denial of Service","id":"CVE-2024-20353","kev_date_added":"2024-04-24","published":"2024-04-24"},{"cvss_score":7.8,"headline":"Cisco Adaptive Security Appliance (ASA) CLI Remote Code Execution","id":"CVE-2016-6367","kev_date_added":"2022-05-24","published":"2016-08-18"},{"cvss_score":7.5,"headline":"Cisco ASA and FTD Read-Only Path Traversal","id":"CVE-2020-3452","kev_date_added":"2021-11-03","published":"2020-07-22"},{"cvss_score":7.5,"headline":"Cisco ASA and FTD Information Disclosure","id":"CVE-2020-3259","kev_date_added":"2024-02-15","published":"2020-05-06"}],"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":"2024-08-02","vendors":["Cisco"]},"summary":"An attacker can intercept SAML assertions via a modified login URL to hijack remote access VPN sessions and gain network access.","url":"https://insights.sbomify.com/CVE-2023-20264/"}
