Almost 900 servers have been compromised using a critical Zimbra Collaboration Suit (ZCS) vulnerability, which at the time was a zero-day left without a patch for nearly 1.5 months. This vulnerability was tracked as CVE-2022-41352 which allows an adversary to send an email with a malicious archive attachment that plants itself as a web-shell in the ZCS server and at the same time, bypassing anti-virus security checks. This CVE is marked as 9.8, making it critical. According to cyber security researchers, 876 servers have been compromised by Advanced Persistent Threats (APTs) before the vulnerability was marked as a CVE. After the vulnerability was marked as a CVE, hackers moved to mass server compromising with as many servers worldwide before admins patched the systems and shut the door to intruders.
