CyberRota Analysis

AI-Generated

FeatherPanel versions prior to 1.3.7.10 are vulnerable due to inadequate permission validation in the SubuserController updateSubuser handler, allowing authenticated subusers to escalate their privileges. This flaw enables a subuser with limited permissions to craft a request that grants them full control over the server, potentially exposing sensitive data and configurations. Organizations using affected versions should prioritize patching to mitigate the risk of unauthorized access and data breaches.

Original NVD Description

FeatherPanel versions before 1.3.7.10 fail to validate permissions in the SubuserController updateSubuser handler, allowing authenticated subusers to modify their own permission records. A subuser with minimal permissions can send a crafted request to grant themselves full server control, enabling unauthorized access to sensitive data, backups, and server configuration.
