Summary

In Capital Embedded AR Classic 431-422 (All versions), Capital Embedded AR Classic R20-11 (All versions < V2303), and multiple Desigo PXC/PXM devices (All versions >= V2.3), the affected product does not properly validate input bounds before accessing packet data. This could allow an unauthenticated remote attacker to trigger memory reads outside the intended packet boundaries.

Risk Assessment

An unauthenticated attacker can read data outside the packet buffer, potentially leading to information disclosure or device failure in building automation environments.

Recommendation

Update Capital Embedded AR Classic to V2303 or later and Desigo PXC/PXM to the latest versions, and limit network exposure of these devices.
