FreeBSD : SnappyMail -- multiple mXSS in HTML sanitizer (bd940aba-7467-11ef-a5c4-08002784c58d)

medium Nessus Plugin ID 207338

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the bd940aba-7467-11ef-a5c4-08002784c58d advisory.

 Oskar reports:

 SnappyMail uses the `cleanHtml()` function to cleanup HTML and CSS in emails. Research discovered that the function has a few bugs which cause an mXSS exploit. Because the function allowed too many (invalid) HTML elements, it was possible (with incorrect markup) to trick the browser to fix the broken markup into valid markup. As a result a motivated attacker may be able to inject javascript.


Tenable has extracted the preceding description block directly from the FreeBSD security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
