Security readout for executives and security teams
CVE-2022-41352 lets an unauthenticated attacker abuse Zimbra's mail-processing path to place files where the web application can access them. The reported impact includes access to other user accounts. Because CISA lists it in KEV and the CVSS score is 9.8, exposed Zimbra systems should be treated as urgent. Organizations running Zimbra Collaboration 8.8.15 or 9.0 are most exposed, especially internet-facing mail servers. Red Hat or CentOS deployments after version 6 may lack pax by default, increasing relevance of the cpio extraction path described by Zimbra. Treat this as an immediate remediation and investigation item for any exposed Zimbra deployment. The vulnerability is critical, remotely reachable, unauthenticated, and listed by CISA as known exploited. Mitigation focus: Install pax where absent so amavis prefers it over cpio.; Review Zimbra Security Advisories for vendor-supported fixes or updates.; Prioritize internet-facing Zimbra 8.8.15 and 9.0 systems..

Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
