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-2021-34788 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-2021-34788/ (Markdown: https://insights.sbomify.com/CVE-2021-34788/index.md)","id":"CVE-2021-34788","markdown":"https://insights.sbomify.com/CVE-2021-34788/index.md","name":"CVE-2021-34788","record":{"aliases":["GHSA-mh72-74m7-v766"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"VPN client","requires_auth":"low_privilege","summary":"Local authenticated attackers can execute arbitrary code with root privileges via a race condition in shared library loading if the HostScan module is installed.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"anyconnect_secure_mobility_client","vendor":"cisco"}],"cvss":{"score":7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-367","name":"Time-of-check Time-of-use (TOCTOU) Race Condition"}],"description":"A vulnerability in the shared library loading mechanism of Cisco AnyConnect Secure Mobility Client for Linux and Mac OS could allow an authenticated, local attacker to perform a shared library hijacking attack on an affected device if the VPN Posture (HostScan) Module is installed on the AnyConnect client. This vulnerability is due to a race condition in the signature verification process for shared library files that are loaded on an affected device. An attacker could exploit this vulnerability by sending a series of crafted interprocess communication (IPC) messages to the AnyConnect process. A successful exploit could allow the attacker to execute arbitrary code on the affected device with root privileges. To exploit this vulnerability, the attacker must have a valid account on the system.","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":"Race condition in Cisco AnyConnect Secure Mobility Client","id":"CVE-2021-34788","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:anyconnect_secure_mobility_client","products":["cisco:anyconnect_secure_mobility_client"],"type":"race_condition","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco Tetration Stored Cross-Site Scripting Vulnerability","id":"CVE-2021-34789"},"packages":[],"prev":{"headline":"Security feature bypass in Cisco Adaptive Security Appliance (ASA) Software","id":"CVE-2021-34787"},"products":["Cisco AnyConnect Secure Mobility Client"],"published":"2021-10-06","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":"2024-11-07","vendors":["Cisco"]},"summary":"Local authenticated attackers can execute arbitrary code with root privileges via a race condition in shared library loading if the HostScan module is installed.","url":"https://insights.sbomify.com/CVE-2021-34788/"}
