remote code injection issue
According to the private advisory published by Fortra, the zero-day is a remote code injection issue that impacts GoAnywhere MFT. The vulnerability can only be exploited by attackers with access to the administrative console of the application.
Installs with administrative consoles and management interfaces that are not exposed on the internet are safe, however, security researcher Kevin Beaumont discovered about 1000 Internet-facing consoles.
Fortra recommends GoAnywhere MFT customers review all administrative users and monitor for unrecognized usernames, especially those created by the system.
Hatch Bank announced that it is working to implement additional safeguards and training for its employees. The company is providing access to credit monitoring services for one year, through Cyberscout, to the impacted customers.
Hatch Bank is also providing impacted customers with guidance on how to better protect against fraudulent activities, such as identity theft and fraud.
