It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-1536 in the wild and no public exploit code.\n\nAffected product: Cisco Webex Meetings Online. 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-2021-1536/ (Markdown: https://insights.sbomify.com/CVE-2021-1536/index.md)","id":"CVE-2021-1536","markdown":"https://insights.sbomify.com/CVE-2021-1536/index.md","name":"CVE-2021-1536","record":{"aliases":["GHSA-hwgc-9p3v-8ffx"],"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 Webex Desktop App","requires_auth":"low_privilege","summary":"Local authenticated attackers can execute arbitrary code with elevated privileges via DLL injection in Cisco Webex applications.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"webex_meetings_desktop","vendor":"cisco"},{"product":"webex_meetings_online","vendor":"cisco"},{"product":"webex_meetings_server","vendor":"cisco"},{"product":"webex_network_recording_player","vendor":"cisco"},{"product":"webex_teams","vendor":"cisco"}],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-427","name":"Uncontrolled Search Path Element"}],"description":"A vulnerability in Cisco Webex Meetings Desktop App for Windows, Cisco Webex Meetings Server, Cisco Webex Network Recording Player for Windows, and Cisco Webex Teams for Windows could allow an authenticated, local attacker to perform a DLL injection attack on an affected device. To exploit this vulnerability, the attacker must have valid credentials on the Windows system. This vulnerability is due to incorrect handling of directory paths at run time. An attacker could exploit this vulnerability by inserting a configuration file in a specific path in the system, which can cause 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 system with the privileges of another user account.","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 Webex Meetings, Webex Network Recording Player, and Webex Teams DLL Injection Vulnerability","id":"CVE-2021-1536","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:webex_meetings_online","products":["cisco:webex_meetings_online","cisco:webex_meetings_server"],"type":"code_injection","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco ThousandEyes Recorder Information Disclosure Vulnerability","id":"CVE-2021-1537"},"packages":[],"prev":{"headline":"Cisco SD-WAN vManage Information Disclosure Vulnerability","id":"CVE-2021-1535"},"products":["Cisco Webex Teams"],"published":"2021-06-04","related":[{"cvss_score":7.8,"headline":"Cisco Webex Network Recording Player and Webex Player Memory Corruption Vulnerability","id":"CVE-2021-1502","kev_date_added":null,"published":"2021-06-04"},{"cvss_score":7.8,"headline":"Cisco Webex Meetings Desktop App Update Service Command Injection Vulnerability","id":"CVE-2018-15442","kev_date_added":null,"published":"2018-10-24"}],"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":"2024-11-07","vendors":["Cisco"]},"summary":"Local authenticated attackers can execute arbitrary code with elevated privileges via DLL injection in Cisco Webex applications.","url":"https://insights.sbomify.com/CVE-2021-1536/"}
