TITLE

Brocade Fibre Channel SAN Run on product Brocade Fabric OS Vulnerability in which privileges are elevated

Trust: 0.8

sources: JVNDB: JVNDB-2016-008578

DESCRIPTION

A privilege escalation vulnerability in Brocade Fibre Channel SAN products running Brocade Fabric OS (FOS) releases earlier than v7.4.1d and v8.0.1b could allow an authenticated attacker to elevate the privileges of user accounts accessing the system via command line interface. With affected versions, non-root users can gain root access with a combination of shell commands and parameters. HP StoreFabric B-series Switches are prone to a remote privilege-escalation vulnerability. A remote attacker can leverage this issue to gain elevated privileges within the context of affected system. HP StoreFabric B-series Switches FOS versions prior to 7.4.1d and 8.0.1b are vulnerable. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Note: the current version of the following document is available here: https://h20564.www2.hpe.com/hpsc/doc/public/display?docId=emr_na-hpesbst03739en_us SUPPORT COMMUNICATION - SECURITY BULLETIN Document ID: hpesbst03739en_us Version: 1 HPESBST03739 rev.1 - HPE StoreFabric B-series Switches, Remote Elevation of Privilege NOTICE: The information in this Security Bulletin should be acted upon as soon as possible.
