Summary
AVM FRITZ!OS before 6.30 extracts the contents of firmware updates before verifying their cryptographic signature, which allows remote attackers to create symlinks or overwrite critical files, and consequently execute arbitrary code, via a crafted firmware image.
Exploit prediction
6.14% chance of exploitation in the next 30 days, higher than 93% of all scored CVEs (FIRST EPSS, 2026-11-09).
