Debian DLA-869-1 : cgiemail security update

high Nessus Plugin ID 97964

Language:

Synopsis

The remote Debian host is missing a security update.

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 tempaltes 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.

For Debian 7 'Wheezy', these problems have been fixed in version 1.6-37+deb7u1.

We recommend that you upgrade your cgiemail packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected cgiemail package.
