Name of the Vulnerable Software and Affected Versions homeLYnk (Wiser For KNX) versions prior to V2.60 spaceLYnk versions prior to V2.60

Description The issue is related to the use of a broken or risky cryptographic algorithm, which could allow an attacker to gain unauthorized access to protected information after discovering credentials through a brute force attack. This could potentially lead to unauthorized access when credentials are compromised.

Recommendations For homeLYnk (Wiser For KNX) versions prior to V2.60, update to a version that uses a secure cryptographic algorithm to prevent unauthorized access. For spaceLYnk versions prior to V2.60, update to a version that uses a secure cryptographic algorithm to prevent unauthorized access. As a temporary workaround, consider restricting access to sensitive information and implementing additional security measures to minimize the risk of exploitation.
