CVE-2024-48842 is a hard-coded credentials vulnerability in ABB FLXeon controllers. The provided content identifies this issue as affecting FLXeon devices through firmware version 9.3.5, including multiple FBXi, FBVi, FBTi, and CBXi product variants referenced in CISA advisory ICSA-25-310-03. Because credentials are hard-coded in the product, an attacker who knows or can recover those embedded credentials may be able to authenticate to the device using vendor-embedded or otherwise non-changeable account material, bypassing normal trust assumptions around unique device credentials. The advisory characterizes the issue as remotely exploitable with low attack complexity.
