Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-1221 in the wild and no public exploit code.\n\nAffected product: Cisco Webex Meetings. 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-2021-1221/ (Markdown: https://insights.sbomify.com/CVE-2021-1221/index.md)","id":"CVE-2021-1221","markdown":"https://insights.sbomify.com/CVE-2021-1221/index.md","name":"CVE-2021-1221","record":{"aliases":["GHSA-9qvw-hfpr-cvx6"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Webex Meetings","requires_auth":"low_privilege","summary":"An authenticated attacker can inject malicious hyperlinks into meeting invitation emails, potentially tricking recipients into visiting attacker-controlled sites.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"webex_meetings","vendor":"cisco"},{"product":"webex_meetings_server","vendor":"cisco"}],"cvss":{"score":4.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-74","name":"Improper Neutralization of Special Elements in Output Used by a Downstream Component"},{"id":"CWE-20","name":"Improper Input Validation"}],"description":"A vulnerability in the user interface of Cisco Webex Meetings and Cisco Webex Meetings Server Software could allow an authenticated, remote attacker to inject a hyperlink into a meeting invitation email. The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by entering a URL into a field in the user interface. A successful exploit could allow the attacker to generate a Webex Meetings invitation email that contains a link to a destination of their choosing. Because this email is sent from a trusted source, the recipient may be more likely to click the link.","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 and Cisco Webex Meetings Server Software Hyperlink Injection Vulnerability","id":"CVE-2021-1221","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cisco:webex_meetings","products":["cisco:webex_meetings","cisco:webex_meetings_server"],"type":"xss","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco Smart Software Manager Satellite SQL Injection Vulnerability","id":"CVE-2021-1222"},"packages":[],"prev":{"headline":"Cisco IOS XE Software Web UI Denial of Service Vulnerabilities","id":"CVE-2021-1220"},"products":["Cisco WebEx Meetings Server"],"published":"2021-02-04","related":[{"cvss_score":9.6,"headline":"Memory corruption in Cisco WebEx Recording Format and Advanced Recording Format Players","id":"CVE-2017-12368","kev_date_added":null,"published":"2017-11-30"},{"cvss_score":9.6,"headline":"Memory corruption in Cisco WebEx Recording Format and Advanced Recording Format Players","id":"CVE-2017-12369","kev_date_added":null,"published":"2017-11-30"},{"cvss_score":9.6,"headline":"Memory corruption in Cisco WebEx Recording Format and Advanced Recording Format Players","id":"CVE-2017-12370","kev_date_added":null,"published":"2017-11-30"},{"cvss_score":9.6,"headline":"Memory corruption in Cisco WebEx Recording Format and Advanced Recording Format Players","id":"CVE-2017-12371","kev_date_added":null,"published":"2017-11-30"},{"cvss_score":9.6,"headline":"Memory corruption in Cisco WebEx Recording Format and Advanced Recording Format Players","id":"CVE-2017-12372","kev_date_added":null,"published":"2017-11-30"},{"cvss_score":8.8,"headline":"Cisco Webex Meetings Desktop App for Mac Update Feature Code Execution Vulnerability","id":"CVE-2020-3342","kev_date_added":null,"published":"2020-06-18"},{"cvss_score":8.1,"headline":"Cisco Webex Meetings and Cisco Webex Meetings Server Token Handling Unauthorized Access Vulnerability","id":"CVE-2020-3361","kev_date_added":null,"published":"2020-06-18"}],"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":"2024-11-08","vendors":["Cisco"]},"summary":"An authenticated attacker can inject malicious hyperlinks into meeting invitation emails, potentially tricking recipients into visiting attacker-controlled sites.","url":"https://insights.sbomify.com/CVE-2021-1221/"}
