CVE-2023-28811

There is a buffer overflow in the password recovery feature of Hikvision NVR/DVR models.

MEDIUM 6.5EPSS 0.39%

Does this matter?

Lower severity and a low EPSS score (0.39%). Track it; it rarely justifies an emergency change on its own.

Description

There is a buffer overflow in the password recovery feature of Hikvision NVR/DVR models. If exploited, an attacker on the same local area network (LAN) could cause the device to malfunction by sending specially crafted packets to an unpatched device.
