An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2020-3482 and fix it if it is affected.\n\nWhat it is: CVE-2020-3482 is a medium-severity vulnerability in Cisco TelePresence Video Communication Server (VCS) Expressway, published on 18 Nov 2020. 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-2020-3482 in the wild and no public exploit code.\n\nAffected product: Cisco TelePresence Video Communication Server (VCS) Expressway. 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-2020-3482/ (Markdown: https://insights.sbomify.com/CVE-2020-3482/index.md)","id":"CVE-2020-3482","markdown":"https://insights.sbomify.com/CVE-2020-3482/index.md","name":"CVE-2020-3482","record":{"aliases":["GHSA-r379-mpqq-hxmh"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["security_bypass","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Expressway","requires_auth":"none","summary":"Unauthenticated attackers can bypass security controls to send traffic to restricted destinations, gaining unauthorized network access.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"expressway","vendor":"cisco"},{"product":"telepresence_video_communication_server","vendor":"cisco"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","version":"3.0"},"cwes":[{"id":"CWE-269","name":"Improper Privilege Management"},{"id":"CWE-284","name":"Improper Access Control"}],"description":"A vulnerability in the Traversal Using Relays around NAT (TURN) server component of Cisco Expressway software could allow an unauthenticated, remote attacker to bypass security controls and send network traffic to restricted destinations. The vulnerability is due to improper validation of specific connection information by the TURN server within the affected software. An attacker could exploit this issue by sending specially crafted network traffic to the affected software. A successful exploit could allow the attacker to send traffic through the affected software to destinations beyond the application, possibly allowing the attacker to gain unauthorized network access.","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":"Cisco Expressway Software Unauthorized Access Information Disclosure Vulnerability","id":"CVE-2020-3482","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Duo Network Gateway (DNG) Information Disclosure Vulnerability","id":"CVE-2020-3483"},"packages":[],"prev":{"headline":"Clam AntiVirus (ClamAV) Software Null Pointer Dereference Vulnerability","id":"CVE-2020-3481"},"products":["Cisco TelePresence Video Communication Server (VCS) Expressway"],"published":"2020-11-18","related":[{"cvss_score":9.6,"headline":"Cross-site request forgery in Cisco TelePresence Video Communication Server (VCS) Expressway","id":"CVE-2024-20252","kev_date_added":null,"published":"2024-02-07"},{"cvss_score":9.6,"headline":"Cross-site request forgery in Cisco TelePresence Video Communication Server (VCS) Expressway","id":"CVE-2024-20254","kev_date_added":null,"published":"2024-02-07"},{"cvss_score":9,"headline":"Cisco Expressway Series and Cisco TelePresence Video Communication Server Vulnerabilities","id":"CVE-2022-20812","kev_date_added":null,"published":"2022-07-06"},{"cvss_score":9,"headline":"Cisco Expressway Series and Cisco TelePresence Video Communication Server Vulnerabilities","id":"CVE-2022-20813","kev_date_added":null,"published":"2022-07-06"},{"cvss_score":8.6,"headline":"Denial of service in Cisco Expressway Series Software and Cisco TelePresence VCS Software All versions prior to version X8.8.2 are vulnerable","id":"CVE-2017-3790","kev_date_added":null,"published":"2017-02-01"},{"cvss_score":8.2,"headline":"Cross-site request forgery in Cisco TelePresence Video Communication Server (VCS) Expressway","id":"CVE-2024-20255","kev_date_added":null,"published":"2024-02-07"},{"cvss_score":6.7,"headline":"Cisco Expressway Series and TelePresence Video Communication Server Remote Code Execution Vulnerability","id":"CVE-2021-34716","kev_date_added":null,"published":"2021-08-18"}],"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-11-13","vendors":["Cisco"]},"summary":"Unauthenticated attackers can bypass security controls to send traffic to restricted destinations, gaining unauthorized network access.","url":"https://insights.sbomify.com/CVE-2020-3482/"}
