CVE-2024-21782

Authenticated command execution via crafted scp string

Published Feb 14, 2024 · Updated May 12, 2025

Command injection in F5 BIG-IP and BIG-IQ allows local users with scp access to execute arbitrary system commands. The scp utility accepts a specially crafted command string without fully neutralizing shell control characters, leaving the earlier correction incomplete. Exploitation requires a Resource Administrator or Certificate Manager account without Advanced shell access and grants command execution with that account's system privileges.
