Team ENVY, a Security Research TEAM has found a flaw that allows for a remote code execution on the
NVR
. An attacker enters a special value for a specific URL parameter, resulting in a NULL pointer reference and a reboot of the NVR. The manufacturer has released patch firmware for the flaw, please refer to the manufacturers report for details and workarounds.
A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
