Zavio

Zavio manufactures a line of compact IP cameras and firmware for small-business surveillance, with its vulnerability footprint concentrating across products such as the B8220, B8520, and CB6231 models. The vendor's disclosures skew strongly toward critical-severity outcomes and frequently acquire public exploit code, driven by recurrent memory-safety weaknesses—including stack-based buffer overflows and out-of-bounds writes—alongside authentication flaws such as hard-coded credentials and OS command injection that expose these devices to remote compromise. Defenders should prioritize inventory and network segmentation of affected camera models, as their internet-facing deployment and firmware-update inertia amplify exposure; live severity and exploitation counts are shown alongside this summary.
