Advisory Timeline
2018-07-31 - [R1] Initial Release
Synopsis
SecurityCenter leverages third-party software to help provide underlying
functionality. Two separate third-party components (PHP and jQuery) were found
to contain vulnerabilities, and updated versions have been made available by
the providers.
Out of caution and in line with good practice, Tenable opted to upgrade the
bundled libraries to address the potential impact of these issues in
SecurityCenter. SecurityCenter 5.7.0 updates PHP to version 7.1.15 and jQuery
to version 3.3.1 to address the identified vulnerabilities. Please see the
Additional References section below for related information and CVE ID's.
Several additional vulnerabilities have also been fixed in SecurityCenter
5.7.0:
1. In SecurityCenter versions prior to 5.7.0, a username enumeration issue
could allow an unauthenticated attacker to automate the discovery of username
aliases via brute force, ultimately facilitating unauthorized access. Server
response output has been unified to correct this issue. (CVE-2018-1154)
2. In SecurityCenter versions prior to 5.7.0, a cross-site scripting (XSS)
issue could allow an authenticated attacker to inject JavaScript code into an
image filename parameter within the Reports feature area. Properly updated
input validation techniques have been implemented to correct this issue.
(CVE-2018-1155)
Solution
Tenable has released SecurityCenter 5.7.0 to address these issues. The
installation files can be obtained from the Tenable Downloads Portal
