The security update was applied automatically and requires no customer intervention.<\/p>\n<p>Following the exploitation of the ACE vulnerability (CVE-2023-7102) by UNC4841, Barracuda has observed new variants of SEASPY and SALTWATER malware deployed on a limited number of ESG devices. On December 22, 2023, Barracuda deployed a patch to remediate compromised ESG devices that showed signs of compromise associated with the newly identified malware variants.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[German]Barracuda has discoverd during an ongoing investigation that a threat actor is exploiting the CVE-2023-7102 vulnerability in the Barracuda Email Security Gateway Appliance (ESG).
