An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-3117 in the wild and no public exploit code.\n\nAffected product: Cisco Web Security 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-2020-3117/ (Markdown: https://insights.sbomify.com/CVE-2020-3117/index.md)","id":"CVE-2020-3117","markdown":"https://insights.sbomify.com/CVE-2020-3117/index.md","name":"CVE-2020-3117","record":{"aliases":["GHSA-mg6c-ww2w-mv2h"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Web Security Appliance","requires_auth":"none","summary":"Unauthenticated attackers can inject arbitrary HTTP headers into responses via crafted URLs, potentially bypassing security controls on Cisco WSAs and SMAs.","user_interaction":"required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"content_security_management_appliance","vendor":"cisco"},{"product":"web_security_appliance","vendor":"cisco"}],"cvss":{"score":4.7,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:L/A:N","version":"3.0"},"cwes":[{"id":"CWE-113","name":"Improper Neutralization of CRLF Sequences in HTTP Headers"}],"description":"A vulnerability in the API Framework of Cisco AsyncOS for Cisco Web Security Appliance (WSA) and Cisco Content Security Management Appliance (SMA) could allow an unauthenticated, remote attacker to inject crafted HTTP headers in the web server's response.
