CVE-2019-7229 – ABB HMI Missing Signature Verification

https://notcve.org/view.php?id=CVE-2019-7229

The ABB CP635 HMI uses two different transmission methods to upgrade its firmware and its software components: "Utilization of USB/SD Card to flash the device" and "Remote provisioning process via ABB Panel Builder 600 over FTP." Neither of these transmission methods implements any form of encryption or authenticity checks against the new firmware HMI software binary files. La HMI CP635 de ABB usa dos métodos de transmisión diferentes para actualizar su firmware y sus componentes de software: "Utilization of USB/SD Card to flash the device" y "Remote provisioning process via ABB Panel Builder 600 over FTP.". Ninguno de estos métodos de transmisión implementa ninguna forma de cifrado o comprobación de autenticidad contra los nuevos archivos binarios del software HMI del firmware. ABB HMI fails to perform any signature validation checking during two different transmission methods for upgrade. • http://packetstormsecurity.com/files/153387/ABB-HMI-Missing-Signature-Verification.html http://seclists.org/fulldisclosure/2019/Jun/34 https://search.abb.com/library/Download.aspx?DocumentID=3ADR010376&LanguageCode=en&DocumentPartId=&Action=Launch https://search.abb.com/library/Download.aspx?DocumentID=3ADR010402&LanguageCode=en&DocumentPartId=&Action=Launch https://www.darkmatter.ae/xen1thlabs/abb-hmi-absence-of-signature-verification-vulnerability-xl-19-005 • CWE-494: Download of Code Without Integrity Check •
