Last modified
CVE-2019-18822 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. 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 callrec-rs@.service. The callrec-rs@.service starts the /opt/callrec/bin/rs binary with root privileges, and this binary is owned by callrec. EPSS estimates a 1.36% chance of exploitation in the next 30 days.
