Summary
Multiple Weidmueller products are affected by an OpenSSL vulnerability.
Weidmüller has released new firmwares of the affected products to fix the vulnerability.
Impact
Weidmüller products are vulnerable to a birthday attack referred to as SWEET32. When exploited, the vulnerability may lead to the unauthorized disclosure of information.

Vulnerabilities
Expand / Collapse allThe DES and Triple DES ciphers, as used in the TLS, SSH, and IPSec protocols and other protocols and products, have a birthday bound of approximately four billion blocks, which makes it easier for remote attackers to obtain cleartext data via a birthday attack against a long-duration encrypted session, as demonstrated by an HTTPS session using Triple DES in CBC mode, aka a "Sweet32" attack.
Remediation
Update to new version as listed below.
