Hello Zimbra Friends, Customers & Partners,
Zimbra 9.0.0 “Kepler” Patch 19 and 8.8.15 “James Prescott Joule” Patch 26 are here.
Security Recommendation
Zimbra strongly recommends that you review whether the Proxy Servlet is configured to allow a particular host (via the zimbraProxyAllowedDomains configuration setting on each class of service). Please make sure:
- Each entry in
zimbraProxyAllowedDomainsis a safe and trusted host. - There are NO wild card entries like *.webex.com. Instead use specific hosts like example.webex.com.
