Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-20275 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-2023-20275/ (Markdown: https://insights.sbomify.com/CVE-2023-20275/index.md)","id":"CVE-2023-20275","markdown":"https://insights.sbomify.com/CVE-2023-20275/index.md","name":"CVE-2023-20275","record":{"aliases":["GHSA-6q64-g7xj-vc8f"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco ASA/FTD VPN","requires_auth":"low_privilege","summary":"Authenticated attackers can spoof another VPN user's source IP address in Cisco ASA and FTD AnyConnect SSL VPN tunnels.","user_interaction":"required","vuln_class":"other"},"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":4.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-346","name":"Origin Validation Error"}],"description":"A vulnerability in the AnyConnect SSL VPN feature of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, remote attacker to send packets with another VPN user's source IP address. This vulnerability is due to improper validation of the packet's inner source IP address after decryption. An attacker could exploit this vulnerability by sending crafted packets through the tunnel. A successful exploit could allow the attacker to send a packet impersonating another VPN user's IP address. It is not possible for the attacker to receive return packets.","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 Cisco Adaptive Security Appliance (ASA) Software","id":"CVE-2023-20275","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":"other","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Integer overflow in AMD Athlon™ 3000 Series Desktop Processors with Radeon™ Graphics","id":"CVE-2023-20507"},"packages":[],"prev":{"headline":"Privilege escalation in Cisco AppDynamics","id":"CVE-2023-20274"},"products":["Cisco Adaptive Security Appliance (ASA) Software","Cisco Firepower Threat Defense Software"],"published":"2023-12-12","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":"Authenticated attackers can spoof another VPN user's source IP address in Cisco ASA and FTD AnyConnect SSL VPN tunnels.","url":"https://insights.sbomify.com/CVE-2023-20275/"}
