Description
WordPress plugin Contact Form CFDB7 versions up to and including 1.3.2 are affected by a pre-authentication SQL injection vulnerability that cascades into insecure deserialization (PHP Object Injection). The weakness arises due to insufficient validation of user input in plugin endpoints, allowing crafted input to influence backend queries in unexpected ways. Using specially crafted payloads, this can escalate into unsafe deserialization, enabling arbitrary object injection in PHP. Although the issue is remotely exploitable without authentication, it does require a crafted interaction with the affected endpoint in order to trigger successfully.

CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Executive Summary

This vulnerability affects the WordPress plugin Contact Form CFDB7 versions up to 1.3.2. It is a pre-authentication SQL injection flaw that allows attackers to send crafted input to plugin endpoints, which is not properly validated. This can manipulate backend database queries and escalate into insecure deserialization (PHP Object Injection), enabling arbitrary object injection in PHP. The exploit can be triggered remotely without authentication but requires a specially crafted interaction with the affected endpoint.

Impact Analysis

The vulnerability can lead to severe impacts including full compromise of the affected system. An attacker can execute arbitrary code via PHP object injection, potentially leading to data theft, data manipulation, or complete system takeover. The CVSS score of 9.6 indicates a critical severity with high impact on confidentiality, integrity, and availability.
