Arbitrary code execution via forged FIT configuration
Published Mar 19, 2020 · Updated May 12, 2026
Improper input validation in Siemens RUGGEDCOM ROX before 2.17.1 allows local users to boot arbitrary code via a crafted FIT image. U-Boot accepts a duplicated FIT configuration whose signature still covers the original hashed nodes, then loads the unsigned kernel named by the forged default. Exploitation requires a signed FIT image, control of default configuration selection, and a boot command that does not name a configuration.
