Description · from the CVE record

xrdp is an open source RDP server. xrdp versions prior to 0.10.0 have a vulnerability that allows attackers to make an infinite number of login attempts. The number of max login attempts is supposed to be limited by a configuration parameter `MaxLoginRetry` in `/etc/xrdp/sesman.ini`. However, this mechanism was not effectively working. As a result, xrdp allows an infinite number of login attempts.
