KDE URL handler allows attacker unauthorized access
| kde-url-handler-gain-access (16163) |  High Risk |
Description:
K Desktop Environment (KDE) could allow a remote attacker to gain unauthorized access on the system. By creating a specially-crafted Telnet, rlogin, SSH (Secure Shell) or mailto URL handler containing a dash (-) character prior to the hostname and followed by a command option, a remote attacker could create or overwrite files on the vulnerable system or gain unauthorized access to sensitive information, once the URL is clicked.
