Client-server traffic compromise via weak TLS
Published Aug 28, 2024 · Updated Aug 28, 2024
Weak TLS in OpenText NetIQ Advanced Authentication before 6.3.5.1 allows attackers to compromise client-server traffic. The client-server channel permits an insufficient TLS protocol version when an unnamed service is accessed between devices; OpenText has not disclosed the service or protocol version. Exploitation requires adjacent-network access, low privileges, and user interaction, and can expose or alter traffic and interrupt service.
