high Nessus Plugin ID 93667

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Several vulnerabilities were discovered in wordpress, a web blogging tool. The Common Vulnerabilities and Exposures project identifies the following issues.

CVE-2015-8834: Cross-site scripting (XSS) vulnerability in wp-includes/wp-db.php in WordPress before 4.2.2 allows remote attackers to inject arbitrary web script or HTML via a long comment that is improperly stored because of limitations on the MySQL TEXT data type. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-3440

CVE-2016-4029: WordPress before 4.5 does not consider octal and hexadecimal IP address formats when determining an intranet address, which allows remote attackers to bypass an intended SSRF protection mechanism via a crafted address.

CVE-2016-5836: The oEmbed protocol implementation in WordPress before 4.5.3 allows remote attackers to cause a denial of service via unspecified vectors.

CVE-2016-6634: Cross-site scripting (XSS) vulnerability in the network settings page in WordPress before 4.5 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

CVE-2016-6635: Cross-site request forgery (CSRF) vulnerability in the wp_ajax_wp_compression_test function in wp-admin/includes/ajax- actions.php in WordPress before 4.5 allows remote attackers to hijack the authentication of administrators for requests that change the script compression option.

CVE-2016-7168: Fix a cross-site scripting vulnerability via image filename.

CVE-2016-7169: Fix a path traversal vulnerability in the upgrade package uploader.

For Debian 7 'Wheezy', these problems have been fixed in version 3.6.1+dfsg-1~deb7u12.

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
