Synacor Zimbra Collaborate Suite (ZCS)

Synacor Zimbra Collaboration Suite (ZCS) contains a cross-site scripting (XSS) vulnerability in the Calendar feature that allows an attacker to execute arbitrary code.

Exploitation status

  • CISA has confirmed this is being exploited in the wild. That is an observation of real attacks, not a prediction.
  • It is known to have been used in ransomware campaigns.
  • US federal civilian agencies are required to remediate it by 2022-03-11. That deadline does not bind private companies, but it is a reasonable benchmark for how urgently CISA views it.
