Red Lion SixTRAK and VersaTRAK Series RTUs with authenticated users enabled (UDR-A) any Sixnet UDR message will meet an authentication challenge over UDP/IP. When the same message is received over TCP/IP the RTU will simply accept the message with no authentication challenge.

When user authentication is not enabled the shell can execute commands with the highest privileges.

When the same message comes over TCP/IP the RTU will simply accept the message with no authentication challenge.

The Crimson 3.2 Windows-based configuration tool allows users with administrative access to define new passwords for users and to download the resulting security configuration to a device. If such a password contains the percent (%) character, invalid values will be included, potentially truncating the string if a NUL is encountered. If the simplified password is not detected by the administrator, the device might be left in a vulnerable state as a result of more-easily compromised credentials. Note that passwords entered via the Crimson system web server do not suffer from this vulnerability.

A vulnerability in Red Lion Europe mbNET/mbNET.rokey and Helmholz REX 200 and REX 250 devices with firmware lower 7.3.2 allows an authenticated remote attacker with high privileges to inject malicious HTML or JavaScript code (XSS).

Red Lion Controls Crimson 3.0 versions 707.000 and prior, Crimson 3.1 versions 3126.001 and prior, and Crimson 3.2 versions 3.2.0044.0 and prior are vulnerable to path traversal. When attempting to open a file using a specific path, the user's password hash is sent to an arbitrary host. This could allow an attacker to obtain user credential hashes.

The weak password on the web user interface can be exploited via HTTP or HTTPS. Once such access has been obtained, the other passwords can be changed. The weak password on Linux accounts can be accessed via SSH or Telnet, the former of which is by default enabled on trusted interfaces. While the SSH service does not support root login, a user logging in using either of the other Linux accounts may elevate to root access using the su command if they have access to the associated password.

Authorized users may install a maliciously modified package file when updating the device via the web user interface. The user may inadvertently use a package file obtained from an unauthorized source or a file that was compromised between download and deployment.

A malicious actor having access to the exported configuration file may obtain the stored credentials and thereby gain access to the protected resource. If the same passwords were used for other resources, further such assets may be compromised.

A NULL pointer deference vulnerability has been identified in the protocol converter. An attacker could send a specially crafted packet that could reboot the device running Crimson 3.1 (Build versions prior to 3119.001).

An attacker could send a specially crafted message to Crimson 3.1 (Build versions prior to 3119.001) that could leak arbitrary memory locations.
