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-2024-20337 in the wild and no public exploit code.\n\nAffected product: Cisco Secure Client. 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-2024-20337/ (Markdown: https://insights.sbomify.com/CVE-2024-20337/index.md)","id":"CVE-2024-20337","markdown":"https://insights.sbomify.com/CVE-2024-20337/index.md","name":"CVE-2024-20337","record":{"aliases":["GHSA-j296-jhq5-3x6c"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["account_takeover","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Secure Client","requires_auth":"none","summary":"An attacker can inject CRLF sequences to execute scripts and steal SAML tokens, enabling unauthorized VPN access.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"secure_client","vendor":"cisco"}],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-93","name":"Improper Neutralization of CRLF Sequences"}],"description":"A vulnerability in the SAML authentication process of Cisco Secure Client could allow an unauthenticated, remote attacker to conduct a carriage return line feed (CRLF) injection attack against a user. \r\n\r This vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by persuading a user to click a crafted link while establishing a VPN session. A successful exploit could allow the attacker to execute arbitrary script code in the browser or access sensitive, browser-based information, including a valid SAML token. The attacker could then use the token to establish a remote access VPN session with the privileges of the affected user. Individual hosts and services behind the VPN headend would still need additional credentials for successful access.","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":"Cross-site scripting in Cisco Secure Client","id":"CVE-2024-20337","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2024"},"n_packages":0,"n_references":1,"next":{"headline":"Privilege escalation in Cisco Secure Client","id":"CVE-2024-20338"},"packages":[],"prev":{"headline":"Memory corruption in Cisco Business Wireless Access Point Software","id":"CVE-2024-20336"},"products":["Cisco Secure Client"],"published":"2024-03-06","related":[{"cvss_score":7.3,"headline":"Privilege escalation in Cisco Secure Client","id":"CVE-2024-20338","kev_date_added":null,"published":"2024-03-06"},{"cvss_score":7.1,"headline":"Cisco Secure Client for Windows with VPN Posture (HostScan) Module DLL Hijacking Vulnerability","id":"CVE-2025-20206","kev_date_added":null,"published":"2025-03-05"},{"cvss_score":6.8,"headline":"Auth bypass in Cisco Secure Client","id":"CVE-2024-20391","kev_date_added":null,"published":"2024-05-15"}],"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":"2024-08-01","vendors":["Cisco"]},"summary":"An attacker can inject CRLF sequences to execute scripts and steal SAML tokens, enabling unauthorized VPN access.","url":"https://insights.sbomify.com/CVE-2024-20337/"}
