Local root escalation via writable RPATH
Published Mar 26, 2021 · Updated Aug 3, 2024
Local privilege escalation in CA eHealth Performance Manager 6.3.2.12 and earlier allows local users to execute code as root. The SUID FtpCollector executable searches a writable RPATH for libclntsh.so.10.1 and loads an ehealth-controlled shared library with root privileges. Exploitation requires access as the ehealth operating-system user; the default installation exposes the writable paths, yielding full host control.
