Vulnerability mechanics
Root cause
"Hardcoded backdoor token in validate_token.py allows unauthenticated API access."
Attack vector
An unauthenticated attacker sends an HTTP request to the Ruckus vRioT service API and sets the `Authorization` header to the hardcoded backdoor value. Because `validate_token.py` accepts this hardcoded value as valid, the server grants the attacker access to the API without requiring any legitimate authentication credentials [ref_id=1]. The attack requires only network access to the vRioT service and no prior authentication.
Affected code
The vulnerability resides in `validate_token.py`, which contains a hardcoded API backdoor value. The advisory does not specify the exact file path or version control details beyond the product name "Ruckus vRioT through 1.5.1.0.21" [ref_id=1].
What the fix does
The advisory does not include a published patch or specific remediation guidance. To close the vulnerability, the hardcoded backdoor value must be removed from `validate_token.py` and the token validation logic should enforce proper authentication against a secure, configurable credential store rather than accepting a static literal value [ref_id=1].
Preconditions
- networkNetwork access to the Ruckus vRioT service API endpoint
- inputKnowledge of the hardcoded backdoor Authorization header value
