CVE-2020-7243Public exploitNetwork attack vector

Authenticated code execution via Fetch URL metacharacters

Published Jan 20, 2020 · Updated Aug 4, 2024

OS command injection in Comtech Stampede FX-1010 firmware 7.4.3 allows remote authenticated users to execute commands via the Fetch URL page. The Fetch URL handler fails to neutralize shell metacharacters in the URL field before the value reaches an operating-system command. Administrator access is required, although the documented comtech account and password provide that access in some deployments.
