Description

This security bulletin contains information about 2 vulnerabilities.

1) Cross-site scripting (CVE-ID: CVE-2017-15219)

CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

CVSSv4: 5.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N]

The vulnerability allows a remote authenticated user to read and manipulate data.

The dotCMS 4.1.1 application is vulnerable to Stored Cross-Site Scripting (XSS) affecting a vanity-urls Title field, a containers Description field, and a templates Description field.

2) Path traversal (CVE-ID: CVE-2017-11466)

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

CVSSv4: 8.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]

The vulnerability allows a remote attacker to perform directory traversal attacks.

The vulnerability exists due to input validation error when processing directory traversal sequences in com/dotmarketing/servlets/AjaxFileUploadServlet.class in dotCMS 4.1.1. A remote authenticated attacker can send a specially crafted HTTP request and remote authenticated administrators to upload .jsp files to arbitrary locations via directory traversal sequences in the fieldName parameter to servlets/ajax_file_upload. This results in arbitrary code execution by requesting the .jsp file at a /assets URI.
