Solution Status:

CVE Reference(s):

Description


Multiple vulnerabilities have been discovered in the BackWPup plugin for WordPress, which can be exploited by malicious people to compromise a vulnerable system.

1) Input passed via the "wpabs" parameter to wp-content/plugins/backwpup/app/options-view_log-iframe.php (when "logfile" is set to an existing file) and to wp-content/plugins/backwpup/app/options-runnow-iframe.php (when "jobid" is set to a numeric value) is not properly verified before being used to include files. This can be exploited to include arbitrary files from remote resources placed on a SMB share.

2) Input passed via the "wpabs" parameter to wp-content/plugins/backwpup/app/wp_xml_export.php is not properly verified before being used to include files. This can be exploited to include arbitrary files from remote resources placed on a SMB share.

The vulnerabilities are confirmed in versions 1.5.2 and 1.7.1. Other versions may also be affected.


Solution:
Edit the source code to ensure that input is properly verified.

Provided and/or discovered by:
