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-2021-1237 in the wild and no public exploit code.\n\nAffected product: Cisco Anyconnect Secure Mobility 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-2021-1237/ (Markdown: https://insights.sbomify.com/CVE-2021-1237/index.md)","id":"CVE-2021-1237","markdown":"https://insights.sbomify.com/CVE-2021-1237/index.md","name":"CVE-2021-1237","record":{"aliases":["GHSA-656q-3mvc-v648"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Cisco AnyConnect Client","requires_auth":"low_privilege","summary":"Local authenticated attackers can execute arbitrary code with SYSTEM privileges via DLL injection in Cisco AnyConnect Secure Mobility Client for Windows.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"anyconnect_secure_mobility_client","vendor":"cisco"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-427","name":"Uncontrolled Search Path Element"}],"description":"A vulnerability in the Network Access Manager and Web Security Agent components of Cisco AnyConnect Secure Mobility Client for Windows could allow an authenticated, local attacker to perform a DLL injection attack. To exploit this vulnerability, the attacker would need to have valid credentials on the Windows system. The vulnerability is due to insufficient validation of resources that are loaded by the application at run time. An attacker could exploit this vulnerability by inserting a configuration file in a specific path in the system which, in turn, causes a malicious DLL file to be loaded when the application starts. A successful exploit could allow the attacker to execute arbitrary code on the affected machine with SYSTEM privileges.","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 AnyConnect Secure Mobility Client for Windows DLL Injection Vulnerability","id":"CVE-2021-1237","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:anyconnect_secure_mobility_client","products":["cisco:anyconnect_secure_mobility_client"],"type":"code_injection","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco Firepower Management Center Stored Cross-Site Scripting Vulnerabilities","id":"CVE-2021-1238"},"packages":[],"prev":{"headline":"Multiple Cisco Products Snort Application Detection Engine Policy Bypass Vulnerability","id":"CVE-2021-1236"},"products":["Cisco AnyConnect Secure Mobility Client"],"published":"2021-01-13","related":[{"cvss_score":7.8,"headline":"Cisco AnyConnect Secure Mobility Client for Windows DLL Hijacking","id":"CVE-2020-3433","kev_date_added":"2022-10-24","published":"2020-08-17"},{"cvss_score":6.5,"headline":"Cisco AnyConnect Secure Mobility Client for Windows Uncontrolled Search Path","id":"CVE-2020-3153","kev_date_added":"2022-10-24","published":"2020-02-19"},{"cvss_score":9.3,"headline":"Security feature bypass in n/a","id":"CVE-2012-3088","kev_date_added":null,"published":"2012-09-16"},{"cvss_score":9.3,"headline":"Code injection in n/a","id":"CVE-2012-2493","kev_date_added":null,"published":"2012-06-20"},{"cvss_score":9.3,"headline":"Code injection in n/a","id":"CVE-2011-2040","kev_date_added":null,"published":"2011-06-02"},{"cvss_score":7.8,"headline":"Privilege escalation in Cisco Secure Client","id":"CVE-2023-20178","kev_date_added":null,"published":"2023-06-28"},{"cvss_score":7.8,"headline":"Cisco AnyConnect Secure Mobility Client for Windows with VPN Posture (HostScan) Module DLL Hijacking Vulnerability","id":"CVE-2021-1366","kev_date_added":null,"published":"2021-02-17"}],"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":"2024-11-12","vendors":["Cisco"]},"summary":"Local authenticated attackers can execute arbitrary code with SYSTEM privileges via DLL injection in Cisco AnyConnect Secure Mobility Client for Windows.","url":"https://insights.sbomify.com/CVE-2021-1237/"}
