CVE-2019-18822: Eleveo call recording improper privilege management vulnerability

Eleveo · Call Recording

A privilege escalation vulnerability in ZOOM Call Recording 6.3.1 allows its user account (i.e., the account under which the program runs - by default, the callrec account) to elevate privileges to root by abusing the [email protected]. The [email protected] starts the /opt/callrec/bin/rs binary with root privileges, and this binary is owned by callrec. It can be replaced by a Trojan horse.
