Last modified Jun 17, 2026

CVE-2022-37042 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. Zimbra Collaboration Suite (ZCS) 8.8.15 and 9.0 has mboximport functionality that receives a ZIP archive and extracts files from it. By bypassing authentication (i.e., not having an authtoken), an attacker can upload arbitrary files to the system, leading to directory traversal and remote code execution. CISA has confirmed active exploitation in the wild. EPSS estimates a 88.26% chance of exploitation in the next 30 days.
