[codec] Questions for Apache Commons Codec information disclosure

[De Zhi Mou <dz...@hcl.com>]

Hi,

Our product received this vulnerability, apache-commons-codec-info-disc (177835).
In the advisory references, there is a link to https://www.whitesourcesoftware.com/vulnerability-database/WS-2019-0379
which says Apache commons-codec before version “commons-codec-1.13-RC1” is vulnerable to information disclosure due to Improper Input validation.

We want to know what kind of improper input validation would cause the vulnerability. I look through all the references but cannot get that information. Are there any examples or testing codes?
We do not directly use codec in our product, but we use HttpClient, which requires codec. Are we still vulnerable or not in this case?

Really appreciate for your help. Thanks.


Regards,
Paul
