CVE-2023-27850

Arbitrary file access via ReadySHARE symlink following

Published Mar 10, 2023 · Updated Feb 28, 2025

Improper link resolution in ReadySHARE on NETGEAR RAX30 before 1.0.10.94 allows attackers to read and modify arbitrary device files. ReadySHARE automatically exposes inserted USB drives or configured shares and follows crafted symlinks from a share into arbitrary router paths. Exploitation requires a prepared USB drive or permission to configure a share; guest FTP or unauthenticated HTTP can then reach the linked files.
