An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2017-3823 exists.\n\nAffected product: Cisco Webex Meetings Server. 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-2017-3823/ (Markdown: https://insights.sbomify.com/CVE-2017-3823/index.md)","id":"CVE-2017-3823","markdown":"https://insights.sbomify.com/CVE-2017-3823/index.md","name":"CVE-2017-3823","record":{"aliases":["GHSA-jvxg-m38c-9fg2"],"analysis":{"component_type":"browser","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco WebEx browser extension","requires_auth":"none","summary":"Remote attackers can execute arbitrary code with browser privileges by tricking users into visiting malicious pages using vulnerable Cisco WebEx browser extensions.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"activetouch_general_plugin_container","vendor":"cisco"},{"product":"download_manager","vendor":"cisco"},{"product":"gpccontainer_class","vendor":"cisco"},{"product":"webex","vendor":"cisco"},{"product":"webex_meeting_center","vendor":"cisco"},{"product":"webex_meetings_server","vendor":"cisco"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"An issue was discovered in the Cisco WebEx Extension before 1.0.7 on Google Chrome, the ActiveTouch General Plugin Container before 106 on Mozilla Firefox, the GpcContainer Class ActiveX control plugin before 10031.6.2017.0126 on Internet Explorer, and the Download Manager ActiveX control plugin before 2.1.0.10 on Internet Explorer. A vulnerability in these Cisco WebEx browser extensions could allow an unauthenticated, remote attacker to execute arbitrary code with the privileges of the affected browser on an affected system. This vulnerability affects the browser extensions for Cisco WebEx Meetings Server and Cisco WebEx Centers (Meeting Center, Event Center, Training Center, and Support Center) when they are running on Microsoft Windows. The vulnerability is a design defect in an application programing interface (API) response parser within the extension. An attacker that can convince an affected user to visit an attacker-controlled web page or follow an attacker-supplied link with an affected browser could exploit the vulnerability. If successful, the attacker could execute arbitrary code with the privileges of the affected browser.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2017-01-21","github_poc":0,"max_poc_stars":null,"metasploit":1,"nuclei":0,"refs":[{"date":"2017-01-21","kind":"metasploit","ref":"exploit/windows/browser/cisco_webex_ext","stars":null,"title":"Cisco WebEx Chrome Extension RCE (CVE-2017-3823)"}],"tier":"weaponised"},"has_fix":null,"headline":"Code injection in Cisco WebEx browser extensions","id":"CVE-2017-3823","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:webex_meetings_server","products":["cisco:webex_meetings_server"],"type":"code_injection","year":"2017"},"n_packages":0,"n_references":8,"next":{"headline":"Denial of service in Cisco IOS XE 15.x","id":"CVE-2017-3824"},"packages":[],"prev":{"headline":"Missing authorization in Cisco Firepower Threat Defense Software versions 6.1.x","id":"CVE-2017-3822"},"products":["Cisco WebEx browser extensions"],"published":"2017-02-01","related":[],"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)"},{"class":"attribution","licence":"BSD-3-Clause","name":"Metasploit"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"Remote attackers can execute arbitrary code with browser privileges by tricking users into visiting malicious pages using vulnerable Cisco WebEx browser extensions.","url":"https://insights.sbomify.com/CVE-2017-3823/"}
