Affected sectors

Risk evaluation

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.

Mitigation summary

Access to the WBM should be limited to trustworthy networks or peers.
