Zimbra Credential Theft Vulnerability Exploited in Attacks
The US Cybersecurity and Infrastructure Security Agency (CISA) informed organizations on Thursday that a recently patched vulnerability affecting the Zimbra enterprise email solution has been exploited in attacks.
The security hole, tracked as CVE-2022-27924 and described as a Memcache injection issue, allows an unauthenticated attacker to steal cleartext credentials from a targeted Zimbra instance without any user interaction.
An attacker can leverage the compromised credentials to access the victim’s emails, from where they could escalate their access within the targeted organization and obtain sensitive information. Access to mailboxes can also allow the attacker to impersonate users and spy on victims.
Zimbra says its products are used by more than 200,000 organizations worldwide.
The vulnerability was fully fixed in May with the release of versions 8.8.15 with patch level 31.1 and 9.0.0 with patch level 24.1.
Code security firm Sonar, whose researchers discovered the flaw, publicly disclosed the details of the vulnerability on June 14, when it also published a video showing the exploit in action.
