CVE-2019-6453

HIGH

mIRC <7.55 - Command Injection

Title source: llm
STIX 2.1

Description

mIRC before 7.55 allows remote command execution by using argument injection through custom URI protocol handlers. The attacker can specify an irc:// URI that loads an arbitrary .ini file from a UNC share pathname. Exploitation depends on browser-specific URI handling (Chrome is not exploitable).
