Vendor: F5 Networks

Description
The vulnerability allows a local attacker to obtain potentially sensitive information on the target system.

The weakness exists in F5 BIG-IP running on VIPRIONi  due to the '/usr/bin/safenet-sync.sh' script to synchronize SafeNet External Network hardware security module (HSM) configuration elements between blades in a clustered deployment writes the HSM partition password in cleartext to the '/var/log/ltm' log file. A local attacker can obtain the SafeNet External Network HSM password.

Mitigation
Install update from vendor's website.
