VAR-200603-0486

Vulnerability from variot - Updated: 2025-04-03 22:36

nuauth in NuFW before 1.0.21 does not properly handle blocking TLS sockets, which allows remote authenticated users to cause a denial of service (service hang) by flooding packets at the authentication server. NuFW is susceptible to a remote denial-of-service vulnerability. This issue is due to the application's failure to properly handle excessive authentication requests. This issue results in the 'nuauth' module failing to respond to new authentication requests, denying service to further users. NuFW versions prior to 1.0.21 are affected by this issue
