CVE-2019-3924 is an intermediary vulnerability affecting MikroTik RouterOS versions prior to 6.43.12 (stable) and 6.42.12 (long-term). This flaw allows a remote, unauthenticated attacker to bypass the router's firewall or conduct network scanning by forcing the device to execute user-defined network requests to both WAN and LAN clients. With a CVSS score of 7.5 (HIGH), this vulnerability is easily exploitable over the network with low attack complexity, potentially leading to high confidentiality impact. While not listed on CISA's KEV catalog and with no observed active exploitation, a public exploit (EDB-46444) exists, though community discussion and media coverage are minimal.
