cdelafuente-r7 at March 03, 2021 6:11pm UTC reported:
Accellion’s legacy File Transfer Appliance (FTA) is an application to transfer large files securely. It is a 20-year-old product and will reach End of Life on April 30, 2021. Accellion recommends to migrate to kiteworks, its enterprise content firewall platform. According to this post, the SQL injection vulnerability is the starting point of a series of attacks against multiple organizations. This post reports that this vulnerability has been actively exploited since mid-December 2020 and is related to an ongoing ransomware campaign.
This SQL injection vulnerability enables an unauthenticated remote attacker to retrieve data from the database by sending specially crafted requests to the document_root
file. Especifically, it has been exploited to retrieve a key that led to the installation of a web shell on the appliance. This web shell was then used to download sensitive data from the FTA internal database.
Due to the nature of this application, the data available is likely to be very sensitive and exploiting this vulnerability would lead to a critical information leak. As an emergency mitigation, external access to any vulnerable FTA should be shut down. However, this won’t block attacks coming from the internal network. It is highly recommended to patch to the latest version and to consider migrating to kiteworks.
