CVE-2024-39917: Neutrinolabs Xrdp

Critical severity, CVSS 9.8. EPSS: 0.6% chance of exploitation in the next 30 days.

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.

Affected products

• Neutrinolabs Xrdp: before 0.10.0 (fixed in 0.10.0)
