Description
Stack-based Buffer Overflow vulnerability in ABB RMC-100, ABB RMC-100 LITE. When the REST interface is enabled by the user, and an attacker gains access to the control network, and user/password broker authentication is enabled, and CVE-2025-6074 is exploited, the attacker can overflow the buffer for username or password. This issue affects RMC-100: from 2105457-043 through 2105457-045; RMC-100 LITE: from 2106229-015 through 2106229-016.
