Users of the GoAnywhere secure managed file transfer (MFT) software have been warned about a zero-day exploit that malicious actors can target directly from the internet.
The GoAnywhere MFT is made by Fortra, known until recently as HelpSystems, and it’s designed to enable organizations to automate and secure the exchange of data with their trading partners.
Cybersecurity blogger Brian Krebs broke the news about the zero-day vulnerability on Thursday, saying that the company had temporarily implemented a service outage in response.
An advisory obtained by Krebs — it can only be accessed by authenticated users — describes it as a zero-day remote code injection exploit and says that “the attack vector of this exploit requires access to the administrative console of the application”.
According to the vendor, the vulnerable admin console should in most cases only be accessible from within a company’s network, through a VPN, or only by trusted IP addresses. However, the company has admitted that some GoAnywhere users may be exposing the console to the public internet.
