CVE-2017-15270
This can be used by attackers to hide data in the Graphical User Interface (GUI) view and create arbitrary entries to a certain extent.
Does this matter?
A public exploit is published in Exploit-DB, so the technical barrier is gone even though the severity is medium and EPSS is 7.0%. Treat it as high on anything reachable from the internet.
Description
The PSFTPd 10.0.4 Build 729 server does not properly escape data before writing it into a Comma Separated Values (CSV) file. This can be used by attackers to hide data in the Graphical User Interface (GUI) view and create arbitrary entries to a certain extent. Special characters such as '"' and ',' and '\r' are not escaped and can be used to add new entries to the log.
