Attackers can exploit this issue to exhaust the maximum number of connections alotted for servers. Successful attacks will deny access to legitimate users. FortressSSH 5.0 is vulnerable; other versions may also be affected. https://gitlab.com/exploit-database/exploitdb-bin-sploits/-/raw/main/bin-sploits/30989.zip
