This vulnerability has a CVSS 3.1 base score of 4.7, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
An issue was discovered in Zimbra Collaboration (ZCS) 10.0 and 10.1. A hardcoded Flickr API key and secret are present in the publicly accessible Flickr Zimlet used by Zimbra Collaboration. Because these credentials are embedded directly in the Zimlet, any unauthorized party could retrieve them and misuse the Flickr integration. An attacker with access to the exposed credentials could impersonate the legitimate application and initiate valid Flickr OAuth flows. If a user is tricked into approving such a request, the attacker could gain access to the user s Flickr data. The hardcoded credentials have since been removed from the Zimlet code, and the associated key has been revoked.
Remediation
Check the references section for vendor advisories and patches from zimbra. Update collaboration to the latest patched version.
