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.

Rittal Chiller SK 3232-Series web interface as built upon Carel pCOWeb firmware A1.5.3 – B1.2.4. The authentication mechanism on affected systems is configured using hard-coded credentials. These credentials could allow attackers to influence the primary operations of the affected systems, namely turning the cooling unit on and off and setting the temperature set point.

Rittal Chiller SK 3232-Series web interface as built upon Carel pCOWeb firmware A1.5.3 – B1.2.4. The authentication mechanism on affected systems does not provide a sufficient level of protection against unauthorized configuration changes. Primary operations, namely turning the cooling unit on and off and setting the temperature set point, can be modified without authentication.

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.

Stored XSS was discovered in Carel pCOWeb prior to B1.2.4, as demonstrated by the config/pw_snmp.html "System contact" field.

The Glen Dimplex Deutschland GmbH implementation of the Carel pCOWeb configuration tool allows remote attackers to obtain access via an HTTP session on port 10000, as demonstrated by reading the modem password (which is 1234), or reconfiguring "party mode" or "vacation mode."
