AI-suggested
- Immediate upgrade to SiYuan version 3.6.1 or later, where the vulnerability is patched with proper path validation.
- Restrict access to the publish-service and authenticated endpoints to trusted users only, employing strong authentication and authorization controls.
- Implement network segmentation and firewall rules to limit exposure of the SiYuan desktop application to untrusted networks.
- Monitor and audit access logs for unusual GET /assets/*path requests that may indicate exploitation attempts.
- Conduct a thorough review of sensitive files stored locally on systems running vulnerable versions and assess potential data exposure.
- Employ endpoint detection and response (EDR) solutions to detect anomalous file copying or access patterns related to the vulnerability.
- Educate users about the risks of pasting untrusted HTML content containing file:// links into SiYuan to reduce attack vectors.
- If upgrading immediately is not feasible, consider disabling or restricting the vulnerable API endpoints temporarily as a stopgap measure.
Description
SiYuan is a personal knowledge management system. In versions 3.6.0 and below, the /api/lute/html2BlockDOM on the desktop copies local files pointed to by file:// links in pasted HTML into the workspace assets directory without validating paths against a sensitive-path list. Together with GET /assets/*path, which only requires authentication, a publish-service visitor can cause the desktop kernel to copy any readable sensitive file and then read it via GET, leading to exfiltration of sensitive files. This issue has been fixed in version 3.6.1.
