What is CVE-2025-9725?

The Cudy LT500E device, up to version 2.3.12, contains a vulnerability in its web interface where a hard-coded password is stored, allowing for unauthorized access. This issue necessitates a local exploitation approach and is compounded by the complexity of execution. Although the hard-coded password 'admin' has been deprecated in version 2.3.13, older versions remain susceptible. Users are urged to upgrade to version 2.3.13 to eliminate this security risk, mandating a new password upon the first login, which must contain at least eight characters.
