Summary

Com-Server firmware versions prior to 1.60 support the insecure TLS 1.0 and TLS 1.1 protocols, which are susceptible to man-in-the-middle attacks and thereby compromise the confidentiality and integrity of data.

Impact

An attacker with network access could exploit the use of insecure TLS 1.0 and TLS 1.1 protocols to intercept and manipulate encrypted communications between the Com-Server and connected systems. This could lead to unauthorized data access, credential theft, compromising the confidentiality and integrity of transmitted information.

Affected Product(s)

Model no. Product name Affected versions
58664 Com-Server 20mA Firmware <1.60
58461 Com-Server OEM Firmware <1.60
58662 Com-Server PoE 3x Isolated Firmware <1.60
58669 Com-Server UL Firmware <1.60
58665 Com-Server++ Firmware <1.60
