At a glance

CVE-2021-24170 is a medium-severity Exposure of Sensitive Information to an Unauthorized Actor vulnerability in the User Profile Picture WordPress plugin, affecting versions < 2.5.0. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity; high confidentiality impact). The issue is fixed in version 2.5.0; sites on affected versions should update now. Disclosed March 2021, reported by Chloe Chamberland.

Vulnerability Overview

The REST API endpoint get_users in the User Profile Picture WordPress plugin before 2.5.0 returned more information than was required for its functionality to users with the upload_files capability. This included password hashes, hashed user activation keys, usernames, emails, and other less 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-200: Exposure of Sensitive Information to an Unauthorized Actor

Reaching this weakness in User Profile Picture < 2.5.0 takes a caller who can reach the endpoint. Sensitive information exposure means data the application intended to keep internal is returned to a caller who should not be able to see it.

The disclosed data — credentials, tokens, customer records or internal paths — is usually worth more as material for a follow-up attack than as an end in itself. For User Profile Picture the fix is 2.5.0: builds < 2.5.0 are affected, anything from 2.5.0 onward is not.

Remediation

Update to version 2.5.0, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: User Profile Picture 2.5.0 closes this, and updating the plugin is the step that ends it.
