Anviz products were disclosed with two high-severity vulnerabilities affecting both endpoint devices and management software. CVE-2026-40066 impacts Anviz CX2 Lite and CX7 devices, where the update mechanism accepts unverified packages and then unpacks and executes them as scripts. The weakness, classified as CWE-494, can enable unauthenticated remote code execution with high impact on confidentiality, integrity, and availability.
A second flaw, CVE-2026-40434, affects Anviz CrossChex Standard and stems from improper verification of the source of a communication channel. Classified as CWE-940, the issue allows an attacker on the same network to inject TCP packets and alter or disrupt client-server traffic, creating high integrity and availability risk. The disclosures were tied to CISA ICS advisory materials and related CSAF documentation, indicating coordinated reporting around security weaknesses in Anviz access-control and workforce management technology.
