Description

Cleartext storage and exposure of WPA2 credentials, and missing authentication on the rr/wr memory read/write commands, in the unauthenticated UART debug console of the Tenda N300 F3 (V603) allow a physically proximate attacker to obtain stored WPA2 credentials in cleartext and to read or write arbitrary memory via the serial console.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
