Mitigating Controls (NIST 800-53 r5)AI
Directly mitigates CVE-2025-25155 by identifying, reporting, and correcting the path traversal flaw in Music Sheet Viewer versions <=4.1 through patching.
Enforces input validation on pathname parameters to the WordPress plugin, blocking path traversal attempts to arbitrary files.
Requires enforcement of access controls that limit file reads to authorized directories, addressing unauthorized arbitrary file access via path traversal.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
The path traversal vulnerability in the public-facing WordPress plugin enables unauthenticated remote exploitation of the application to read arbitrary server files, directly mapping to T1190 (Exploit Public-Facing Application) for initial access and T1005 (Data from Local System) for collection of sensitive data from the local filesystem.
