K73926196: PHPMailer vulnerability CVE-2016-10045

Security Advisory

Original Publication Date: Feb 14, 2017
Updated Date: Dec 21, 2017

Security Advisory Description

The isMail transport in PHPMailer before 5.2.20 might allow remote attackers to
pass extra parameters to the mail command and consequently execute arbitrary
code by leveraging improper interaction between the escapeshellarg function and
internal escaping performed in the mail function in PHP.  NOTE: this
vulnerability exists because of an incorrect fix for CVE-2016-10033. (
CVE-2016-10045)

Impact

The Configuration utility component of affected products allows a Manager role
user to set the sender field, which can exploit the PHPMailer component. As a
result, the remote arbitrary code execution in the context of the web server
user is affected and may remotely compromise the target web application.

Security Advisory Status

F5 Product Development has assigned ID 638556 (BIG-IP) and ID 638533 (WebSafe)
to this vulnerability.

Security Advisory Recommended Actions

If you are running a version listed in the Versions known to be vulnerable
column, you can eliminate this vulnerability by upgrading to a version listed
in the Versions known to be not vulnerable column. If the table lists only an
older version than what you are currently running, or does not list a
non-vulnerable version, then no upgrade candidate currently exists.
