Описание
The command “ipfilter” in Brocade Fabric OS before Brocade Fabric OS v.9.0.1a, v8.2.3, and v8.2.0_CBN4, and v7.4.2h uses unsafe string function to process user input. Authenticated attackers can abuse this vulnerability to exploit stack-based buffer overflows, allowing execution of arbitrary code as the root user account.

The request handling functions in web management interface of Brocade Fabric OS versions before v9.0.1a, v8.2.3a, and v7.4.2h do not properly handle malformed user input, resulting in a service crash. An authenticated attacker could use this weakness to cause the FOS HTTP application handler to crash, requiring a reboot.
