This Week’s Top Story
A flaw in Barracuda’s email security gateway was exploited by hackers for months
Barracuda, an enterprise security firm, disclosed this past Tuesday that a recently patched zero-day flaw in its Email Security Gateway (ESG) appliances has been abused by hackers to backdoor the company’s devices for the past seven months. The critical vulnerability, CVE-2023-2868, has been exploited by these threat actors since October 2022 and wasn’t identified by Barracuda until May 19, 2023. Patches for the flaw were released by Barracuda on May 20 and 21.
The flaw, which impacts versions 5.1.3.001 through 9.2.0.006, allows a remote attacker to achieve code execution on susceptible installations. Barracuda identified that attackers executed malware on a subset of appliances, and also found that data was exfiltrated on a subset of appliances. To date, three malware strains have been found on impacted appliances: SALTWATER, SEASPY, and SEASIDE, and each of them exhibits one or more malicious functions.
Mandiant has been investigating the incident, and has found that one of the strains’ source code, SEASPY, overlaps with an open source backdoor called cd00r. At this time, Mandiant and Barracuda have not attributed the attacks to any known threat actors. Barracuda also did not disclose how many organizations were breached as a result of the flaw, but assured that the investigation into the incident is ongoing.
