Synopsis

The remote host is missing Sun Security Patch number 152650-02.

Description

The remote Solaris host is missing patch number 152650-02. It is, therefore, affected by a local privilege escalation vulnerability in the dtappgather binary due to improper handling of user-supplied arguments. A local attacker can exploit this, via a specially crafted command, to manipulate file permissions and create a user-owned directory anywhere on the system with root privileges. The attacker can then add shared objects to the folder and run setuid binaries with a library file, resulting in root privileges.

EXTREMEPARR is one of multiple Equation Group vulnerabilities and exploits disclosed on 2017/04/08 by a group known as the Shadow Brokers.

Solution

You should install patch 152650-02 for your system to be up-to-date.
