CVE-2020-8284  (opens in a new tab)
CWE-200  (opens in a new tab)

How to fix?

There is no fixed version for RHEL:7 curl.

NVD Description

Note: Versions mentioned in the description apply only to the upstream curl package and not the curl package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

A malicious server can use the FTP PASV response to trick curl 7.73.0 and earlier into connecting back to a given IP address and port, and this way potentially make curl extract information about services that are otherwise private and not disclosed, for example doing port scanning and service banner extractions.
