FortiAuthenticator multiple vulnerabilities

Risk 3 Medium

Date Feb 05 2015

Impact Local file disclosure, Local passwords disclosure, reflected XSS

CVE ID CVE-2015-1455, CVE-2015-1456, CVE-2015-1457, CVE-2015-1459

Fixed In Firmware 3.2.1

Impact

Older versions of FortiAuthenticator are subject to three vulnerabilities:

1. Local passwords disclosure: Upon booting, passwords for local accounts (eg:
PostgreSQL) are logged to the startup debug logs. These local accounts can 
however only be accessed by a user who already has shell access to the 
FortiAuthenticator.

2. Local file system disclosure: An admin user with CLI access can view local
files on the local filesystem by using the -f option of the dig command.

3. Reflected XSS: A remote attacker can perform a reflected XSS attack via an
improperly sanitized parameter.

Note:

The "subshell bypass" vulnerability claimed by security-assessment.com 
(CVE-2015-1458) is not acknowledged as a vulnerability by Fortinet: A 
support-provided debug-kit is needed to write the 
"'/tmp/privexec/dbgcore_enable_shell_access" file from an admin account, and 
in turn obtain root shell. This is a feature used for advanced 
troubleshooting.

Affected Products

Password disclosure and local file disclosure (CVE-2015-1456, CVE-2015-1455, 
CVE-2015-1457) affect FortiAuthenticator

Reflected XSS (CVE-2015-1459) affect FortiAuthenticator

Solutions

Upgrade to FortiAuthenticator 3.2.1 or higher.
