CVE-2012-0898
At a glance
CVE-2012-0898 is a medium-severity Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the myEASYbackup WordPress plugin, affecting versions < 1.0.9. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 1.0.9; sites on affected versions should update now. Disclosed January 2012, reported by antiphastrophus.
Vulnerability Overview
Directory traversal vulnerability in meb_download.php in the myEASYbackup plugin 1.0.8.1 for WordPress allows remote attackers to read arbitrary files via a .. (dot dot) in the dwn_file parameter.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user.
CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Reaching this weakness in myEASYbackup < 1.0.9 takes a caller who can reach the endpoint. Path traversal happens when user-controlled text is used to build a filesystem path without being constrained to an intended directory, so sequences like ../ walk the resolved path somewhere else.
Depending on the operation, it means reading files outside the intended folder — wp-config.php being the usual target — or writing to and deleting paths the web server can touch. For myEASYbackup the fix is 1.0.9: builds < 1.0.9 are affected, anything from 1.0.9 onward is not.
Remediation
Update to version 1.0.9, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to myEASYbackup: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: myEASYbackup 1.0.9 closes this, and updating the plugin is the step that ends it.
