CVE-2022-28859Network attack vector

Partition password disclosure via Net HSM scripts

Published May 5, 2022 · Updated Sep 16, 2024

Information exposure in F5 BIG-IP 14.1.x and 15.1.x allows remote authenticated users to obtain the Net HSM partition password. The nethsm-safenet-install.sh and nethsm-thales-install.sh scripts write the supplied partition password into a log during Net HSM setup. Exposure occurs only while Net HSM is being installed and compromises the credential's confidentiality without altering data or interrupting service.
