CVE-2023-51357

Vulnerability

Overview The Conversios.io plugin for WooCommerce (versions 6.5.0 and earlier) suffers from a missing authorization vulnerability. The software fails to properly verify access control for certain functions, allowing exploitation of incorrectly configured security levels. This broken access control issue stems from a lack of required privileges or nonce checks, enabling unauthorized actions without authentication [1].

Attack

Vector and Exploitation As a network-based attack with low complexity, an attacker can exploit this vulnerability without needing any prior authentication. The attack surface is broad: it can be used in mass-exploit campaigns against thousands of WordPress websites simultaneously, regardless of site size or traffic. No user interaction is required, and the vulnerability is expected to become actively exploited [1].

Impact

Successful exploitation enables an unprivileged attacker to perform actions normally reserved for higher-privileged users. This can lead to unauthorized modification of site settings, data exposure, or other elevated privileges, compromising the security of the WooCommerce store [1].

Mitigation

Status The vulnerability is patched in version 6.5.1 of the plugin. Users are strongly advised to update immediately. If immediate update is not possible, hosting providers or developers should be engaged to apply mitigations. Patchstack has also released a virtual mitigation rule to block exploitation attempts until the update is applied [1].
