CyberRota Analysis

AI-Generated

The TillKit WordPress plugin prior to version 1.0.5 is vulnerable due to its failure to require a change of the hard-coded PIN for the privileged POS account upon activation, allowing unauthenticated attackers to exploit the public POS login endpoint. This vulnerability can lead to unauthorized access to sensitive customer and site-user data, as well as potential modifications to store data. WordPress site administrators using this plugin should prioritize updating to the latest version to mitigate the risk of data breaches.

Original NVD Description

The TillKit WordPress plugin before 1.0.5 does not require the hard-coded, publicly known PIN of the privileged POS account it creates on activation to be changed before use, and it authenticates its public POS login endpoint on that PIN alone with no identity or capability check, allowing unauthenticated attackers to obtain a privileged POS session and thereby read customer and site-user personal data and modify store data.
