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-2020-3549 in the wild and no public exploit code.\n\nAffected product: Cisco Secure Firewall Management Center. 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-2020-3549/ (Markdown: https://insights.sbomify.com/CVE-2020-3549/index.md)","id":"CVE-2020-3549","markdown":"https://insights.sbomify.com/CVE-2020-3549/index.md","name":"CVE-2020-3549","record":{"aliases":["GHSA-gcqw-x5jp-ph78"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Firepower Management Center","requires_auth":"none","summary":"An attacker can intercept sftunnel traffic to obtain registration hashes, enabling decryption and modification of configuration and alert data between FMC and FTD devices.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"secure_firewall_management_center","vendor":"cisco"},{"product":"secure_firewall_threat_defense","vendor":"cisco"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-326","name":"Inadequate Encryption Strength"}],"description":"A vulnerability in the sftunnel functionality of Cisco Firepower Management Center (FMC) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to obtain the device registration hash. The vulnerability is due to insufficient sftunnel negotiation protection during initial device registration. An attacker in a man-in-the-middle position could exploit this vulnerability by intercepting a specific flow of the sftunnel communication between an FMC device and an FTD device. A successful exploit could allow the attacker to decrypt and modify the sftunnel communication between FMC and FTD devices, allowing the attacker to modify configuration data sent from an FMC device to an FTD device or alert data sent from an FTD device to an FMC device.","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 Firepower Management Center Software and Firepower Threat Defense Software sftunnel Pass the Hash Vulnerability","id":"CVE-2020-3549","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:secure_firewall_management_center","products":["cisco:secure_firewall_management_center","cisco:secure_firewall_threat_defense"],"type":"weak_cryptography","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco Firepower Management Center Software and Firepower Threat Defense Software Directory Traversal Vulnerability","id":"CVE-2020-3550"},"packages":[],"prev":{"headline":"Cisco Email Security Appliance Denial Of Service Vulnerability","id":"CVE-2020-3548"},"products":["Cisco Firepower Management Center"],"published":"2020-10-21","related":[{"cvss_score":10,"headline":"Cisco Firewall Management Center Authentication Bypass Using an Alternate Path or Channel","id":"CVE-2026-20079","kev_date_added":"2026-09-09","published":"2026-03-04"},{"cvss_score":10,"headline":"Cisco Secure Firewall Management Center (FMC) Software and Cisco Security Cloud Control (SCC) Firewall Management Deserialization of Untrusted Data","id":"CVE-2026-20131","kev_date_added":"2026-03-19","published":"2026-03-04"},{"cvss_score":5.3,"headline":"Cisco Secure Firewall Management Center Use of Hard-coded Password","id":"CVE-2026-20316","kev_date_added":"2026-07-29","published":"2026-07-29"},{"cvss_score":10,"headline":"Cisco Secure Firewall Management Center Software Radius Remote Code Execution Vulnerability","id":"CVE-2025-20265","kev_date_added":null,"published":"2025-08-14"},{"cvss_score":9.9,"headline":"Command injection in Cisco Firepower Management Center","id":"CVE-2024-20424","kev_date_added":null,"published":"2024-10-23"},{"cvss_score":9.9,"headline":"Missing authorization in Cisco Firepower Management Center","id":"CVE-2023-20048","kev_date_added":null,"published":"2023-11-01"},{"cvss_score":9.8,"headline":"Cisco Firepower Management Center Lightweight Directory Access Protocol Authentication Bypass Vulnerability","id":"CVE-2019-16028","kev_date_added":null,"published":"2020-09-23"}],"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-11-13","vendors":["Cisco"]},"summary":"An attacker can intercept sftunnel traffic to obtain registration hashes, enabling decryption and modification of configuration and alert data between FMC and FTD devices.","url":"https://insights.sbomify.com/CVE-2020-3549/"}
