- Severity: CVSS 7.5 (High), CNA
- Vector: CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=total

## Affected

- TP-Link System Inc. Omada Software Controller (Windows): fixed in 6.3.0.45

## Description

In Omada Controller MSP mode, the user-confirmation endpoint fails to enforce the required permission check. An authenticated user can supply a caller-controlled Identifier parameter to validate credentials for another account and receive responses that distinguish nonexistent users, invalid passwords, and successful authentication. Successful exploitation may allow user enumeration, credential verification, and unauthorized access to MSP resources or compromise of targeted accounts.

## What to do
