Total.js CMS Path Traversal
Date: 2022-05
Affected: npm/total4
Attack vector: path-traversal
Category: vulnerability-disclosure
Severity: High
CVE: CVE-2019-15952
CWE: CWE-22
CVSS: 8.8 (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)

An issue was discovered in Total.js CMS 12.0.0. An authenticated user with the Pages privilege can conduct a path traversal attack (../) to include .html files that are outside the permitted directory. Also, if a page contains a template directive, then the directive will be server side processed. Thus, if a user can control the content of a .html file, then they can inject a payload with a malicious template directive to gain Remote Command Execution. The exploit will work only with the .html extension.
