CVE-2024-27442: Zimbra Collaboration

High severity, CVSS 7.8. EPSS: 0.3% chance of exploitation in the next 30 days.

An issue was discovered in Zimbra Collaboration (ZCS) 9.0 and 10.0. The zmmailboxdmgr binary, a component of ZCS, is intended to be executed by the zimbra user with root privileges for specific mailbox operations. However, an attacker can escalate privileges from the zimbra user to root, because of improper handling of input arguments. An attacker can execute arbitrary commands with elevated privileges, leading to local privilege escalation.

Affected products

• Zimbra Collaboration: from 10.0.0, before 10.0.7 (fixed in 10.0.7); version 9.0.0 only
