Opera Telnet file overwrite
|opera-telnet-file-overwrite (16139)||Medium Risk|
Opera could allow a remote attacker to create or overwrite arbitrary files on the system. By creating a specially-crafted Telnet URL 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, once the URL is clicked.
Upgrade to the latest version of Opera (7.50 or later), available from the Opera Web site. See References.
