Security News > 2023 > May > Alert: Hackers Exploit Barracuda Email Security Gateway 0-Day Flaw for 7 Months

Enterprise security firm Barracuda on Tuesday disclosed that a recently patched zero-day flaw in its Email Security Gateway appliances had been abused by threat actors since October 2022 to backdoor the devices.

The latest findings show that the critical vulnerability, tracked as CVE-2023-2868, has been actively exploited for at least seven months prior to its discovery.

The flaw, which Barracuda identified on May 19, 2023, affects versions 5.1.3.001 through 9.2.0.006 and could allow a remote attacker to achieve code execution on susceptible installations.

"CVE-2023-2868 was utilized to obtain unauthorized access to a subset of ESG appliances," the network and email security company said in an updated advisory.

"Malware was identified on a subset of appliances allowing for persistent backdoor access. Evidence of data exfiltration was identified on a subset of impacted appliances."

The U.S. Cybersecurity and Infrastructure Security Agency, last week, also added the bug to its Known Exploited Vulnerabilities catalog, urging federal agencies to apply the fixes by June 16, 2023.
