CyberRota Analysis

AI-Generated

SiYuan versions prior to 3.8.2 are vulnerable due to logging API tokens in plaintext within an accessible log file when full-text search requests exceed certain timing thresholds. This flaw allows authenticated attackers to exploit the getFile endpoint to retrieve sensitive admin API tokens, potentially granting them permanent administrative access to the system. Organizations using affected versions should prioritize remediation to prevent unauthorized access and potential compromise of their systems.

Original NVD Description

SiYuan before v3.8.2 logs API tokens from query parameters in plaintext to an accessible log file when full-text search requests exceed timing thresholds. Authenticated attackers can read the log file via the getFile endpoint to recover admin API tokens and gain permanent administrative access.
