CVE-2026-15203: Debug interfaces are accessible by default in Danfoss iC7 Automation SP, iC7 Marine and iC7 7Hybrid software
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
Affected Software
Remediation
Recommended actions to resolve this vulnerability, in priority order.
- Configuration
Change the configuration so debug interfaces are not accessible by default; restrict access control for debug and engineering interfaces on iC7-Automation SP (Release 2026.2.5-26A) to prevent unauthorized read/write access, unsigned application/EEPROM/firmware uploads, and execution via exposed service/update interfaces.
Danfoss iC7-Automation SP debug interfaces access control = restricted - Configuration
Change the configuration so debug interfaces are not accessible by default; restrict access control for debug and engineering interfaces on iC7-Marine (Release 2026.6.30-GR4.4) to prevent unauthorized read/write access, unsigned application/EEPROM/firmware uploads, and execution via exposed service/update interfaces.
Danfoss iC7-Marine debug interfaces access control = restricted - Configuration
Change the configuration so debug interfaces are not accessible by default; restrict access control for debug and engineering interfaces on iC7-Hybrid (Release 2026.7.2-GR4.5) to prevent unauthorized read/write access, unsigned application/EEPROM/firmware uploads, and execution via exposed service/update interfaces.
