CVE-2015-10105
At a glance
CVE-2015-10105 is a medium-severity Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the IP Blacklist Cloud WordPress plugin, affecting versions <= 3.42. It carries a CVSS score of 4.9 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires an authenticated account at Admin level or above. The issue is fixed in version 3.43; sites on affected versions should update now. Disclosed March 2015.
Vulnerability Overview
The IP Blacklist Cloud plugin for WordPress is vulnerable to Path Traversal in versions up to, and including, 3.42 via the 'filename' parameter. This allows authenticated attackers, with administrative privileges, to read arbitrary files on the server that may contain sensitive information.
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 interaction from a victim user. A successful exploit has high impact on confidentiality.
CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
IP Blacklist Cloud <= 3.42 carries this weakness at filename, and reaching it takes an account at Admin level or above. 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 IP Blacklist Cloud the fix is 3.43: builds <= 3.42 are affected, anything from 3.43 onward is not.
Remediation
Update to version 3.43, or a newer patched version
How does WordSec protect against this?
An attacker needs Admin access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: IP Blacklist Cloud 3.43 closes this, and updating the plugin is the step that ends it.
