IP Cameras

with firmware version M2.1.6.05 are
vulnerable to multiple instances of stack-based overflows. During the
processing and parsing of certain fields in XML elements from incoming
network requests, the product does not sufficiently check or validate
allocated buffer size. This may lead to remote code execution.

Remediation

Vendor Workaround

The affected products are end-of-life and have been identified to contain many insecurities. The vendor, Zavio, is no longer actively in business and therefore development for firmware fixes, mitigations, and updates are not available and will not become available. CISA recommends users discontinue use of the product.
