CVE-2021-28246Public exploit

Local privilege escalation via writable RPATH

Published Mar 26, 2021 · Updated Aug 3, 2024

Privilege escalation in Broadcom CA eHealth Performance Manager 6.3.2.12 and earlier allows local users to execute code as ehealth. The SUID emtgtctl2 executable searches a writable RPATH for absent libkstat.so.1 and loads an attacker's shared object. A regular operating-system account and write access to /prods/ora10/lib are required; successful exploitation permits control of eHealth files and processes.
