VAR-201601-0613

Vulnerability from variot - Updated: 2023-12-18 12:06

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. AVM FRITZ!OS is prone to a remote code-execution vulnerability. Successfully exploiting this issue allows attackers to execute arbitrary code in the context of the affected application. AVM FRITZ!OS versions prior to 6.30 are vulnerable
