In CISA’s Known Exploited Vulnerabilities catalog: Synacor Zimbra Collaboration Suite (ZCS) Arbitrary File Upload Vulnerability.
Added , federal remediation due . Known ransomware use: Known.
Required action: Apply updates per vendor instructions.
Description
An issue was discovered in Zimbra Collaboration (ZCS) 8.8.15 and 9.0. An attacker can upload arbitrary files through amavis via a cpio loophole (extraction to /opt/zimbra/jetty/webapps/zimbra/public) that can lead to incorrect access to any other user accounts. Zimbra recommends pax over cpio. Also, pax is in the prerequisites of Zimbra on Ubuntu; however, pax is no longer part of a default Red Hat installation after RHEL 6 (or CentOS 6). Once pax is installed, amavis automatically prefers it over cpio.
