Description

The cPanel Security Team discovered several security vulnerabilities in cgiemail, a CGI program used to create HTML forms for sending mails:

CVE-2017-5613

A format string injection vulnerability allowed to supply arbitrary format strings to cgiemail and cgiecho. A local attacker with permissions to provide a cgiemail template could use this vulnerability to execute code as webserver user. Format strings in cgiemail templates are now restricted to simple %s, %U and %H sequences.

CVE-2017-5614

An open redirect vulnerability in cgiemail and cgiecho binaries could be exploited by a local attacker to force redirect to an arbitrary URL. These redirects are now limited to the domain that handled the request.

CVE-2017-5615

A vulnerability in cgiemail and cgiecho binaries allowed injection of additional HTTP headers. Newline characters are now stripped from the redirect location to protect against this.

CVE-2017-5616

Missing escaping of the addendum parameter lead to a reflected cross-site (XSS) vulnerability in cgiemail and cgiecho binaries. The output is now html escaped.
