CVE-2017-7907
An Improper XML Parser Configuration issue was discovered in Schneider Electric Wonderware Historian Client 2014 R2 SP1 and prior.
Does this matter?
Lower severity and a low EPSS score (0.39%). Track it; it rarely justifies an emergency change on its own.
Description

An improperly restricted XML parser (with improper restriction of XML external entity reference, or XXE) may allow an attacker to enter malicious input through the application which could cause a denial of service or disclose file contents from a server or connected network.
