A New Critical SolarWinds Zero-Day Vulnerability Under Active Attack

A New Critical SolarWinds Zero-Day Vulnerability Under Active Attack

SolarWinds, the Texas-based company that became the epicenter of a massive supply chain attack late last year, has issued patches to contain a remote code execution flaw in its Serv-U managed file transfer service.

The fixes, which target Serv-U Managed File Transfer and Serv-U Secure FTP products, arrive after Microsoft notified the IT management and remote monitoring software maker that the flaw was being exploited in the wild. The threat actor behind the exploitation remains unknown as yet, and it isn't clear exactly how the attack was carried out.

"Microsoft has provided evidence of limited, targeted customer impact, though SolarWinds does not currently have an estimate of how many customers may be directly affected by the vulnerability," SolarWinds said in an advisory published Friday, adding it's "unaware of the identity of the potentially affected customers."
