It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-20805 in the wild and no public exploit code.\n\nAffected product: Cisco Umbrella Insights Virtual Appliance. 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-2022-20805/ (Markdown: https://insights.sbomify.com/CVE-2022-20805/index.md)","id":"CVE-2022-20805","markdown":"https://insights.sbomify.com/CVE-2022-20805/index.md","name":"CVE-2022-20805","record":{"aliases":["GHSA-5j9q-qmpc-xr4h"],"analysis":{"component_type":"cloud_service","fix_type":"workaround","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Cisco Umbrella SWG","requires_auth":"low_privilege","summary":"An authenticated adjacent attacker can bypass SSL decryption and content filtering in Cisco Umbrella SWG by crafting TLS requests with specific SNI extensions.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"umbrella_secure_web_gateway","vendor":"cisco"}],"cvss":{"score":4.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:C/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-327","name":"Use of a Broken or Risky Cryptographic Algorithm"},{"id":"CWE-693","name":"Protection Mechanism Failure"}],"description":"A vulnerability in the automatic decryption process in Cisco Umbrella Secure Web Gateway (SWG) could allow an authenticated, adjacent attacker to bypass the SSL decryption and content filtering policies on an affected system. This vulnerability is due to how the decryption function uses the TLS Sever Name Indication (SNI) extension of an HTTP request to discover the destination domain and determine if the request needs to be decrypted. An attacker could exploit this vulnerability by sending a crafted request over TLS from a client to an unknown or controlled URL. A successful exploit could allow an attacker to bypass the decryption process of Cisco Umbrella SWG and allow malicious content to be downloaded to a host on a protected network. There are workarounds that address this vulnerability.","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 Umbrella Secure Web Gateway File Decryption Bypass Vulnerability","id":"CVE-2022-20805","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2022"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco Expressway Series and Cisco TelePresence Video Communication Server Vulnerabilities","id":"CVE-2022-20806"},"packages":[],"prev":{"headline":"Cisco Unified Communications Products Denial of Service Vulnerability","id":"CVE-2022-20804"},"products":["Cisco Umbrella Insights Virtual Appliance"],"published":"2022-04-21","related":[{"cvss_score":5.8,"headline":"Cisco Umbrella Secure Web Gateway File Inspection Bypass Vulnerability","id":"CVE-2022-20738","kev_date_added":null,"published":"2022-02-10"}],"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":"partial"},"state":"PUBLISHED","updated":"2024-11-06","vendors":["Cisco"]},"summary":"An authenticated adjacent attacker can bypass SSL decryption and content filtering in Cisco Umbrella SWG by crafting TLS requests with specific SNI extensions.","url":"https://insights.sbomify.com/CVE-2022-20805/"}
