Synopsis

The remote Debian host is missing a security-related update.

Description

Ashley Newson discovered that the XRDP sessions manager was susceptible to denial of service. A local attacker can further take advantage of this flaw to impersonate the XRDP sessions manager and capture any user credentials that are submitted to XRDP, approve or reject arbitrary login credentials or to hijack existing sessions for xorgxrdp sessions.

Solution

Upgrade the xrdp packages.

For the stable distribution (buster), this problem has been fixed in version 0.9.9-1+deb10u1.
