Carel pCOWeb HVAC BACnet Gateway 2.1.0, Firmware: A2.1.0 - B2.1.0, Application Software: 2.15.4A Software v16 13020200 suffers from an unauthenticated arbitrary file disclosure vulnerability. Input passed through the 'file' GET parameter through the 'logdownload.cgi' Bash script is not properly verified before being used to download log files. This can be exploited to disclose the contents of arbitrary and sensitive files via directory traversal attacks.
An issue was discovered in Carel pCOWeb prior to B1.2.4. In /config/pw_changeusers.html the device stores cleartext passwords, which may allow sensitive information to be read by someone with access to the device.
