CVE-2019-18924

Systematic IRIS WebForms 5.4 is vulnerable to directory traversal.

MEDIUM 5.3EPSS 1.30%

Does this matter?

Lower severity and a low EPSS score (1.30%). Track it; it rarely justifies an emergency change on its own.

Description

Systematic IRIS WebForms 5.4 is vulnerable to directory traversal. By manipulating variables that reference files with ../ (and variations), it is possible to list all the directories and check if a particular file exists.
