Vulnerability from cvelistv5 – Published: 2026-08-26 05:36 – Updated: 2026-08-26 14:58

Title

Debug interfaces are accessible by default in Danfoss iC7 Automation SP, iC7 Marine and iC7 7Hybrid software

Summary

Improper access control in debug and engineering interfaces in Danfoss iC7-Automation SP, iC7-Marine, and iC7-Hybrid GR3 allows attackers to gain read/write access to internal values, upload and execute unsigned applications, and upload unsigned EEPROM data and firmware via exposed service interfaces and software update mechanisms

Severity
