Participants Database <= 2.7.8.3 - Missing Authorization to Unauthenticated Arbitrary Record Update / Sensitive Information Exposure via 'id' Parameter

Participants Database: Currently marked unpatched

Affected versions: *-2.7.8.3

Vulnerability type: CWE-862 Missing Authorization

Affected software, patched versions and attribution

The Participants Database plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.7.8.3 via the 'id' parameter. This makes it possible for unauthenticated attackers to overwrite arbitrary participant records by numeric ID and redirect the private_id-bearing record-access link to an attacker-controlled email address, granting full read and edit access to the victim's stored personally identifiable information including names, email addresses, phone numbers, and any other fields collected in the participant database. An attacker can harvest a valid nonce with a plain unauthenticated GET request to any page rendering the public signup or record form, then POST action=update with an arbitrary id value to overwrite any record; chaining a subsequent action=retrieve then delivers the private-access link to the attacker-controlled mailbox.

Participants Database: Currently marked unpatched

Affected versions: *-2.7.8.3

Vulnerability type: CWE-89 Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

Affected software, patched versions and attribution

The Participants Database plugin for WordPress is vulnerable to SQL Injection in versions up to, and including, 2.7.8.3 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

Affected versions: *-2.7.8.3

Vulnerability type: CWE-22 Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

Affected software, patched versions and attribution

The Participants Database plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in all versions up to, and including, 2.7.8.3. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php).
