CVE-2019-6991
A classic Stack-based buffer overflow exists in the zmLoadUser() function in zm_user.cpp of the zmu binary in ZoneMinder through 1.32.3, allowing an unauthenticated attacker to execute code via a long username.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.31%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
