GoKawiilResearchers reverse-engineer MikroTik's undisclosed RouterOS 7.23.4 security patch
MikroTik simultaneously released RouterOS 7.23.4, 7.24.2 and 6.49.21 on September 3, 2026, each flagging an unspecified 'important security update' without disclosing details. A security researcher reverse-engineered the binary diffs across versions and identified two exploitable flaws: a low-exponent RSA signature forgery leading to an mtget buffer overflow, and an SSH authentication bug where a username value of -2 grants a read-only session elevated privileges, enabling full command execution on the router.
