CyberRota Analysis

AI-Generated

Versions of SiYuan prior to v3.7.4 are vulnerable due to insufficient masking of sensitive configuration fields in the /api/system/getConf endpoint, which exposes critical information such as the session-cookie signing key and OS username. This flaw allows unauthorized users to forge session cookies, potentially leading to user impersonation and privilege escalation to administrator levels in instances lacking access-auth codes. Organizations using affected versions should prioritize patching to mitigate the risk of unauthorized access and data compromise.

Original NVD Description

SiYuan versions before v3.7.4 fail to mask sensitive configuration fields in the /api/system/getConf endpoint, allowing anonymous or publish-reader users to obtain the session-cookie signing key, OS username via pandoc path, and encrypted-notebook key material. Attackers can forge and tamper with session cookies to impersonate users, and on instances without access-auth codes configured, escalate to administrator privileges.
