## Description

All versions of the qBittorrent client through 4.5.5 use default
credentials when the web user interface is enabled. The administrator is
not forced to change the default credentials. As of 4.5.5, this issue has
not been fixed. A remote attacker can use the default credentials to
authenticate and execute arbitrary operating system commands using the
"external program" feature in the web user interface. This was reportedly
exploited in the wild in March 2023.
