Description

This security bulletin contains information about 1 vulnerability.


1) Path traversal (CVE-ID: CVE-2016-6517)

CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:P/U:Green


The vulnerability allows a remote attacker to view arbitrary files on the target system.

The vulnerability exists due to improper input validation when processing data passed via the “minifierBundleDir” HTTP GET parameter to “/html/js/barebone.jsp” script. A remote attacker can send a specially crafted HTTP request, containing directory traversal sequences (e.g. %2E%2E (encoded dot dot)) and view contents of arbitrary files on the vulnerable system.
