An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2020-3452 in the wild since at least 3 Nov 2021.\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-2020-3452/ (Markdown: https://insights.sbomify.com/CVE-2020-3452/index.md)","id":"CVE-2020-3452","markdown":"https://insights.sbomify.com/CVE-2020-3452/index.md","name":"CVE-2020-3452","record":{"aliases":["GHSA-q26c-r46f-6fcq"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"Cisco ASA/FTD","requires_auth":"none","summary":"Unauthenticated attackers can read sensitive files via directory traversal if WebVPN or AnyConnect is enabled on Cisco ASA or FTD devices.","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":"secure_firewall_threat_defense","vendor":"cisco"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"},{"id":"CWE-20","name":"Improper Input Validation"}],"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 read sensitive files on a targeted system. The vulnerability is due to a lack of proper input validation of URLs in HTTP requests processed by an affected device. An attacker could exploit this vulnerability by sending a crafted HTTP request containing directory traversal character sequences to an affected device. A successful exploit could allow the attacker to view arbitrary files within the web services file system on the targeted device. The web services file system is enabled when the affected device is configured with either WebVPN or AnyConnect features. This vulnerability cannot be used to obtain access to ASA or FTD system files or underlying operating system (OS) files.","ecosystems":[],"exploits":{"exploitdb":3,"first_seen":"2020-07-24","github_poc":23,"max_poc_stars":98,"metasploit":0,"nuclei":1,"refs":[{"date":"2021-01-05T14:41:13Z","kind":"github_poc","ref":"https://github.com/darklotuskdb/CISCO-CVE-2020-3452-Scanner-Exploiter","stars":98,"title":"CISCO CVE-2020-3452 Scanner \u0026 Exploiter"},{"date":"2020-12-13T13:47:38Z","kind":"github_poc","ref":"https://github.com/cygenta/CVE-2020-3452","stars":26,"title":null},{"date":"2020-07-24T15:04:45Z","kind":"github_poc","ref":"https://github.com/PR3R00T/CVE-2020-3452-Cisco-Scanner","stars":25,"title":"CVE-2020-3452 Cisco ASA Scanner -unauth Path Traversal Check"},{"date":"2020-09-28T05:00:37Z","kind":"github_poc","ref":"https://github.com/3ndG4me/CVE-2020-3452-Exploit","stars":24,"title":"Just basic scanner abusing CVE-2020-3452 to enumerate the standard files accessible in the Web Directory of the CISCO ASA applicances."},{"date":"2020-08-01T08:27:11Z","kind":"github_poc","ref":"https://github.com/0x5ECF4ULT/CVE-2020-3452","stars":23,"title":"CVE-2020-3452 exploit"},{"date":"2020-08-13T08:22:27Z","kind":"github_poc","ref":"https://github.com/murataydemir/CVE-2020-3452","stars":8,"title":"[CVE-2020-3452] Cisco Adaptive Security Appliance (ASA) \u0026 Cisco Firepower Threat Defense (FTD) Web Service Read-Only Directory Traversal"},{"date":"2021-02-03T05:45:53Z","kind":"github_poc","ref":"https://github.com/fuzzlove/Cisco-ASA-FTD-Web-Services-Traversal","stars":6,"title":"CVE-2020-3452 - Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) traversal"},{"date":"2020-11-18T21:31:50Z","kind":"github_poc","ref":"https://github.com/grim3/CVE-2020-3452","stars":4,"title":"CVE-2020-3452"}],"tier":"exploited"},"has_fix":null,"headline":"Cisco ASA and FTD Read-Only Path Traversal","id":"CVE-2020-3452","indexable":true,"kev":{"dateAdded":"2021-11-03","dueDate":"2022-05-03","knownRansomwareCampaignUse":"Unknown","product":"Adaptive Security Appliance (ASA) and Firepower Threat Defense (FTD)","requiredAction":"Apply updates per vendor instructions.","vendorProject":"Cisco","vulnerabilityName":"Cisco ASA and FTD Read-Only Path Traversal Vulnerability"},"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":5,"next":{"headline":"Cisco Small Business RV340 Series Routers Command Injection and Remote Code Execution Vulnerabilities","id":"CVE-2020-3453"},"packages":[],"prev":{"headline":"Cisco Small Business RV340 Series Routers Command Injection and Remote Code Execution Vulnerabilities","id":"CVE-2020-3451"},"products":["Cisco Adaptive Security Appliance (ASA) Software"],"published":"2020-07-22","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 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":"open","licence":"CC0 1.0","name":"CISA KEV"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"yes","exploitation":"active","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-10-21","vendors":["Cisco"]},"summary":"Unauthenticated attackers can read sensitive files via directory traversal if WebVPN or AnyConnect is enabled on Cisco ASA or FTD devices.","url":"https://insights.sbomify.com/CVE-2020-3452/"}
