Description

mIRC contains a flaw that may allow a remote attacker to execute arbitrary code. The issue is triggered due to the DCC Server command, which doesn't properly filter charachters (such as . and \) from file names. It is possible that the flaw may allow a remote attacker to place arbitrary code in a different location, such as the autostart directory, and then require the victim to execute those code, resulting in a loss of integrity.
