This vulnerability has been modified since it was last analyzed by the NVD. It is awaiting reanalysis which may result in further changes to the information provided.
Description
All version of Ewon Flexy and Cosy prior to 14.1 use wildcards such as (*) under which domains can request resources. An attacker with local access and high privileges could inject scripts into the Cross-origin Resource Sharing (CORS) configuration that could abuse this vulnerability, allowing the attacker to retrieve limited confidential information through sniffing.

Description
WebAccess/SCADA Versions 9.0 and prior are vulnerable to cross-site scripting, which may allow an attacker to send malicious JavaScript code to an unsuspecting user, which could result in hijacking of the user’s cookie/session tokens, redirecting the user to a malicious webpage and performing unintended browser actions.
