An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2020-3187 exists.\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-2020-3187/ (Markdown: https://insights.sbomify.com/CVE-2020-3187/index.md)","id":"CVE-2020-3187","markdown":"https://insights.sbomify.com/CVE-2020-3187/index.md","name":"CVE-2020-3187","record":{"aliases":["GHSA-5f48-6vm9-w28v"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"Cisco ASA/FTD","requires_auth":"none","summary":"Unauthenticated attackers can read or delete files in the web services filesystem if WebVPN or AnyConnect is enabled.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"adaptive_security_appliance_software","vendor":"cisco"},{"product":"asa_5505_firmware","vendor":"cisco"},{"product":"asa_5510_firmware","vendor":"cisco"},{"product":"asa_5512-x_firmware","vendor":"cisco"},{"product":"asa_5515-x_firmware","vendor":"cisco"},{"product":"asa_5520_firmware","vendor":"cisco"},{"product":"asa_5525-x_firmware","vendor":"cisco"},{"product":"asa_5540_firmware","vendor":"cisco"},{"product":"asa_5545-x_firmware","vendor":"cisco"},{"product":"asa_5550_firmware","vendor":"cisco"},{"product":"asa_5555-x_firmware","vendor":"cisco"},{"product":"asa_5580_firmware","vendor":"cisco"},{"product":"asa_5585-x_firmware","vendor":"cisco"},{"product":"secure_firewall_threat_defense","vendor":"cisco"}],"cvss":{"score":9.1,"severity":"critical","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.0"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"A vulnerability in the web services interface of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to conduct directory traversal attacks and obtain read and delete access to sensitive files on a targeted system. The vulnerability is due to a lack of proper input validation of the HTTP URL. An attacker could exploit this vulnerability by sending a crafted HTTP request containing directory traversal character sequences. An exploit could allow the attacker to view or delete arbitrary files on the targeted system. When the device is reloaded after exploitation of this vulnerability, any files that were deleted are restored. The attacker can only view and delete files within the web services file system. This file system is enabled when the affected device is configured with either WebVPN or AnyConnect features. This vulnerability can not be used to obtain access to ASA or FTD system files or underlying operating system (OS) files. Reloading the affected device will restore all files within the web services file system.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2020-07-28","github_poc":5,"max_poc_stars":1,"metasploit":0,"nuclei":1,"refs":[{"date":"2020-07-28T04:20:17Z","kind":"github_poc","ref":"https://github.com/CrackerCat/CVE-2020-3187","stars":1,"title":null},{"date":"2024-05-19T11:32:36Z","kind":"github_poc","ref":"https://github.com/Cappricio-Securities/CVE-2020-3187","stars":1,"title":"Cisco Adaptive Security Appliance Software/Cisco Firepower Threat Defense - Directory Traversal"},{"date":"2020-07-29","kind":"exploitdb","ref":"48723","stars":null,"title":"Cisco Adaptive Security Appliance Software 9.7 - Unauthenticated Arbitrary File Deletion"},{"date":"2020-09-11T04:46:59Z","kind":"github_poc","ref":"https://github.com/1337in/CVE-2020-3187","stars":0,"title":null},{"date":"2021-06-14T06:27:11Z","kind":"github_poc","ref":"https://github.com/sujaygr8/CVE-2020-3187","stars":0,"title":null},{"date":"2023-03-14T09:54:38Z","kind":"github_poc","ref":"https://github.com/sunyyer/CVE-2020-3187-Scanlist","stars":0,"title":"Batch scanning site."},{"date":null,"kind":"nuclei","ref":"http/cves/2020/CVE-2020-3187.yaml","stars":null,"title":"Cisco Adaptive Security Appliance Software/Cisco Firepower Threat Defense - Directory Traversal"}],"tier":"weaponised"},"has_fix":null,"headline":"Path traversal in Cisco Adaptive Security Appliance (ASA) Software","id":"CVE-2020-3187","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":"path_traversal","year":"2020"},"n_packages":0,"n_references":2,"next":{"headline":"Cisco Firepower Threat Defense Software Management Interface Denial of Service Vulnerability","id":"CVE-2020-3188"},"packages":[],"prev":{"headline":"Cisco Firepower Threat Defense Software Management Access List Bypass Vulnerability","id":"CVE-2020-3186"},"products":["Cisco Adaptive Security Appliance (ASA) Software"],"published":"2020-05-06","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)"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-11-15","vendors":["Cisco"]},"summary":"Unauthenticated attackers can read or delete files in the web services filesystem if WebVPN or AnyConnect is enabled.","url":"https://insights.sbomify.com/CVE-2020-3187/"}
