Biscom Secure File Transfer (SFT) is a web-based solution that replaces insecure FTP and email, allowing end users to easily send and share files without IT involvement. More about the product is available on the vendor's web site.
These issues were discovered by Orlando Barrera II of Rapid7, Inc, and disclosed in accordance with Rapid7's vulnerability disclosure policy.
After authenticating to the Biscom Secure File Transfer web application, an attacker can alter the "Name" and "Description" fields of a Workspace, as shown in Figures 1, 2, and 3.
As of version 5.1.1025, the issue has been resolved. Absent an update, a web application firewall (WAF) may prevent attackers from entering the malicious XSS, and/or protect users by stripping offending XSS.
Security is the top priority for Biscom and we appreciate Rapid7 identifying this issue and bringing it to our attention. Once we were informed, our team moved quickly to release a patch within a week to address the issue. Biscom is not aware of any customers being impacted by this issue and Biscom sees the likelihood as low since an authenticated user is required. Biscom values the sharing of security information and we thank Rapid7 in evaluating our application's security.
