An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2019-3929 and fix it if it is affected.\n\nWhat it is: CVE-2019-3929 is a critical command injection vulnerability in Crestron AirMedia, Barco WePresent, Extron ShareLink, Teq AV IT WIPS710, SHARP PN-L703WA, Optoma WPS-Pro, Blackbox HD WPS, InFocus LiteShow3, and InFocus LiteShow4., published on 30 Apr 2019. An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2019-3929 in the wild since at least 15 Apr 2022.\n\nAffected product: Crestron AirMedia, Barco WePresent, Extron ShareLink, Teq AV IT WIPS710, SHARP PN-L703WA, Optoma WPS-Pro, Blackbox HD WPS, InFocus LiteShow3, and InFocus LiteShow4.. 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-2019-3929/ (Markdown: https://insights.sbomify.com/CVE-2019-3929/index.md)","id":"CVE-2019-3929","markdown":"https://insights.sbomify.com/CVE-2019-3929/index.md","name":"CVE-2019-3929","record":{"aliases":["GHSA-m297-v8rg-x5fh"],"analysis":{"component_type":"iot_embedded","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Wireless presentation devices","requires_auth":"none","summary":"Remote unauthenticated attackers can execute arbitrary OS commands as root via the file_transfer.cgi endpoint on various wireless presentation devices.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"tenable","cpe":[{"product":"wepresent_wipg-1000p_firmware","vendor":"barco"},{"product":"wepresent_wipg-1600w_firmware","vendor":"barco"},{"product":"hd_wireless_presentation_system_firmware","vendor":"blackbox"},{"product":"am-100_firmware","vendor":"crestron"},{"product":"am-101_firmware","vendor":"crestron"},{"product":"sharelink_200_firmware","vendor":"extron"},{"product":"sharelink_250_firmware","vendor":"extron"},{"product":"liteshow3_firmware","vendor":"infocus"},{"product":"liteshow4_firmware","vendor":"infocus"},{"product":"wps-pro_firmware","vendor":"optoma"},{"product":"pn-l703wa_firmware","vendor":"sharp"},{"product":"wips710_firmware","vendor":"teqavit"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"},{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"The Crestron AM-100 firmware 1.6.0.2, Crestron AM-101 firmware 2.7.0.1, Barco wePresent WiPG-1000P firmware 2.3.0.10, Barco wePresent WiPG-1600W before firmware 2.4.1.19, Extron ShareLink 200/250 firmware 2.0.3.4, Teq AV IT WIPS710 firmware 1.1.0.7, SHARP PN-L703WA firmware 1.4.2.3, Optoma WPS-Pro firmware 1.0.0.5, Blackbox HD WPS firmware 1.0.0.5, InFocus LiteShow3 firmware 1.0.16, and InFocus LiteShow4 2.0.0.7 are vulnerable to command injection via the file_transfer.cgi HTTP endpoint.
