critical Nessus Plugin ID 130521

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Several vulnerabilities in wordpress, a web blogging tool, have been fixed.

CVE-2019-17669

Server Side Request Forgery (SSRF) vulnerability because URL validation does not consider the interpretation of a name as a series of hex characters.

CVE-2019-17670

Server Side Request Forgery (SSRF) vulnerability was reported in wp_validate_redirect(). Normalize the path when validating the location for relative URLs.

CVE-2019-17671

Unauthenticated viewing of certain content (private or draft posts) is possible because the static query property is mishandled.

CVE-2019-17675

Wordpress does not properly consider type confusion during validation of the referer in the admin pages. This vulnerability affects the check_admin_referer() WordPress function.

For Debian 8 'Jessie', these problems have been fixed in version 4.1.28+dfsg-0+deb8u1.

We recommend that you upgrade your wordpress 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 packages.
