CWE-294

Authentication Bypass by Capture-replay

BaseIncompleteSimple108 CVEs
A capture-replay flaw exists when the design of the product makes it possible for a malicious user to sniff network traffic and bypass authentication by replaying it to the server in question to the same effect as the original message (or with minor changes).

Extended description

Capture-replay attacks are common and can be difficult to defeat without cryptography. They are a subset of network injection attacks that rely on observing previously-sent valid commands, then changing them slightly if necessary and resending the same commands to the server.

Common consequences1

  • Access ControlGain Privileges or Assume Identity

    Messages sent with a capture-relay attack allow access to resources which are not otherwise accessible without proper authentication.

Potential mitigations2

  1. Architecture and Design

    Utilize some sequence or time stamping functionality along with a checksum which takes this into account in order to ensure that messages can be parsed only once.

  2. Architecture and Design

    Since any attacker who can listen to traffic can see sequence numbers, it is necessary to sign messages with some kind of cryptography to ensure that sequence numbers are not simply doctored along with content.

ShowMojo MojoBox Digital Lockbox 1.4 is vulnerable to Authentication Bypass. The implementation of the lock opening mechanism via Bluetooth Low Energy (BLE) is vulnerable to replay attacks. A malicious user is able to intercept BLE requests and replicate them to open the lock at any time. Alternatively, an attacker with physical access to the device on which the Android app is installed, can obtain the latest BLE messages via the app logs and use them for opening the lock.

A replay attack vulnerability was discovered in a Zigbee smart home kit manufactured by Ksix (Zigbee Gateway Module = v1.0.3, Door Sensor = v1.0.7, Motion Sensor = v1.0.12), where the Zigbee anti-replay mechanism - based on the frame counter field - is improperly implemented. As a result, an attacker within wireless range can resend captured packets with a higher sequence number, which the devices incorrectly accept as legitimate messages. This allows spoofed commands to be injected without authentication, triggering false alerts and misleading the user through notifications in the mobile application used to monitor the network.
