This vulnerability exists in Tapo C500 Wi-Fi camera due to hard-coded RSA private key embedded within the device firmware. An attacker with physical access could exploit this vulnerability to obtain cryptographic private keys which can then be used to perform impersonation, data decryption and man in the middle attacks on the targeted device. The severity level is classified as high, with a CVSS score of 7, indicating significant risk to organizations.
Risk to organizations includes unauthorized access to sensitive data and potential exploitation of the device functionality. Since this vulnerability requires physical access, the immediate risk may be lower; however, the implications of a successful attack could be severe. Organizations should prioritize patching immediately.
Currently, there are no known public exploits or proof of concept available. The vulnerability status is deferred, meaning that further assessment and potential remediation details may be pending. Organizations should remain vigilant and monitor updates regarding this vulnerability.
The urgency for defenders is high, as any exploitation could lead to significant risks. Security teams must be proactive in addressing any vulnerabilities in their devices to safeguard against potential attacks.
Vulnerability Details
Officially, the vulnerability is described as follows: "This vulnerability exists in Tapo C500 Wi-Fi camera due to hard-coded RSA private key embedded within the device firmware." The vulnerability type is classified under CWE-321, indicating the presence of a hard-coded cryptographic key. The CVSS score is 7, categorized as high severity, reflecting the impact on confidentiality, integrity, and availability.
Technical Analysis
The root cause of this vulnerability stems from the embedding of a hard-coded RSA private key within the firmware of the Tapo C500. This key could be leveraged by an attacker with physical access, allowing them to decrypt data or impersonate the device. The attack vector is physical, with a low complexity level, requiring no special privileges or user interaction.
The confidentiality impact is high, as attackers may gain access to sensitive information. Similarly, integrity and availability impacts are also high, further emphasizing the criticality of this vulnerability.
Risk & Impact Analysis
Organizations deploying Tapo C500 cameras face significant risks due to this vulnerability. The potential for unauthorized access to sensitive data and the ability to perform impersonation and man-in-the-middle attacks poses a serious threat. The blast radius could extend to any connected systems or data streams associated with the compromised device.
Given the CVSS score of 7, organizations are urged to address this vulnerability in their priority patch cycle. Failure to do so may result in severe consequences if an attacker exploits this weakness.
