Lifecycle Timeline
1DescriptionNVD
Unnecessary fields in the OpenTrace/BlueTrace protocol in COVIDSafe through v1.0.17 allow a remote attacker to identify a device model by observing cleartext payload data. This allows re-identification of devices, especially less common phone models or those in low-density situations.
AnalysisAI
Unnecessary fields in the OpenTrace/BlueTrace protocol in COVIDSafe through v1.0.17 allow a remote attacker to identify a device model by observing cleartext payload data. Rated medium severity (CVSS 5.3), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
Technical ContextAI
This vulnerability is classified under CWE-312. Unnecessary fields in the OpenTrace/BlueTrace protocol in COVIDSafe through v1.0.17 allow a remote attacker to identify a device model by observing cleartext payload data.
