CVE-2018-8046
6.1 · MEDIUMOverview
CVE-2018-8046 is a medium-severity vulnerability affecting sencha ext_js. It was published on July 5, 2018 and has a CVSS 3.0 base score of 6.1 (MEDIUM).
This vulnerability has a CVSS 3.0 base score of 6.1, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
The getTip() method of Action Columns of Sencha Ext JS 4 to 6 before 6.6.0 is vulnerable to XSS attacks, even when passed HTML-escaped data. This framework brings no built-in XSS protection, so the developer has to ensure that data is correctly sanitized. However, the getTip() method of Action Columns takes HTML-escaped data and un-escapes it. If the tooltip contains user-controlled data, an attacker could exploit this to create a cross-site scripting attack, even when developers took precautions and escaped data.
Remediation
Check the references section for vendor advisories and patches from sencha. Update ext_js to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
