At a glance
CVE-2015-1000010 is a medium-severity Improper Access Control vulnerability in the Simple Image Manipulator WordPress plugin, affecting versions <= 1.0. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity; high confidentiality impact). No fixed release has been reported yet; treat installations running this software as exposed. Disclosed August 2015, reported by Larry W. Cashdollar.
Vulnerability Overview
The Simple Image Manipulator plugin for WordPress is vulnerable to Remote File Download in versions up to, and including, 1.0. This is due to no authorization checks or user input sanitization being performed in the './simple-image-manipulator/controller/download.php' file. This makes it possible for authenticated attackers to remotely download otherwise restricted files from the vulnerable site.
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-284: Improper Access Control
Reaching this weakness in Simple Image Manipulator <= 1.0 takes a caller who can reach the endpoint. Improper access control means the code decides what a caller may do using something other than their actual permissions, so the decision can be wrong without any check appearing to be missing.
Whoever can shape the request decides the answer, so the protected action runs for callers the code never meant to allow. No fixed build of this plugin is recorded for Simple Image Manipulator yet, so installs running <= 1.0 stay exposed until the vendor ships one.
Remediation
No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.
How does WordSec protect against this?
Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
