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-2021-1503 in the wild and no public exploit code.\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-2021-1503/ (Markdown: https://insights.sbomify.com/CVE-2021-1503/index.md)","id":"CVE-2021-1503","markdown":"https://insights.sbomify.com/CVE-2021-1503/index.md","name":"CVE-2021-1503","record":{"aliases":["GHSA-gwp9-m42j-2f54"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Cisco Webex Player","requires_auth":"none","summary":"Attackers can execute arbitrary code by tricking users into opening malicious Webex recording files, requiring immediate patching of the player software.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"webex_meetings_server","vendor":"cisco"},{"product":"webex_player","vendor":"cisco"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"A vulnerability in Cisco Webex Network Recording Player for Windows and MacOS and Cisco Webex Player for Windows and MacOS could allow an attacker to execute arbitrary code on an affected system. This vulnerability is due to insufficient validation of values in Webex recording files that are in either Advanced Recording Format (ARF) or Webex Recording Format (WRF). An attacker could exploit this vulnerability by sending a user a malicious ARF or WRF file through a link or email attachment and persuading the user to open the file with the affected software on the local system.
