    CVE-2019-6453

    Published: 18 Feb 2019Last Modified: 10 Mar 2026

    Summary:

    Details: 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).
