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.
