CVE-2024-48788 is a vulnerability identified in the YESCAM application component (com.yescom.YesCam.zwave) version 1.0.2, related to the firmware update process. The vulnerability allows a remote attacker to obtain sensitive information due to insufficient protection of data transmitted during firmware updates. The weakness is categorized under CWE-319, which involves the cleartext transmission of sensitive information, indicating that the firmware update mechanism does not adequately encrypt or secure the data in transit. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) indicates that the attack can be performed remotely over the network without any privileges or user interaction, and it impacts confidentiality with a high severity score of 7.5. The vulnerability does not affect integrity or availability, meaning the attacker cannot modify firmware or disrupt device operation but can intercept or extract sensitive data. No patches or fixes have been published at the time of disclosure, and no known exploits have been reported in the wild. The lack of authentication or encryption in the firmware update process exposes devices to potential data leakage, which could include sensitive configuration details or credentials. This vulnerability is particularly concerning for environments relying on YESCAM devices for security or surveillance, as attackers could leverage the exposed information for further attacks or privacy violations.

The primary impact of CVE-2024-48788 is the unauthorized disclosure of sensitive information from YESCAM devices during the firmware update process. This can lead to significant confidentiality breaches, potentially exposing device credentials, configuration data, or other private information. Such exposure could facilitate subsequent attacks, including unauthorized access, device manipulation, or network infiltration. While the vulnerability does not allow direct modification of firmware or denial of service, the leakage of sensitive data undermines trust in the device's security and may compromise the overall security posture of organizations using these devices. Enterprises and consumers relying on YESCAM for surveillance or security monitoring could face privacy violations and increased risk of targeted attacks. The remote and unauthenticated nature of the exploit increases the threat level, as attackers do not need physical access or user interaction. The absence of patches means the vulnerability remains exploitable, increasing the window of risk until mitigations or updates are applied.

To mitigate CVE-2024-48788, organizations should immediately restrict network access to YESCAM devices, especially limiting exposure to untrusted networks or the internet. Implement network segmentation and firewall rules to isolate these devices and control firmware update traffic. Monitor network traffic for unencrypted firmware update transmissions or unusual data flows that could indicate exploitation attempts. Disable automatic or remote firmware updates if possible until a secure patch is released. Engage with the vendor to obtain information on planned patches or updates and apply them promptly once available. Consider deploying network intrusion detection systems (NIDS) with signatures tailored to detect attempts to exploit this vulnerability. Additionally, review and enhance overall IoT device security policies, including strong authentication, encrypted communications, and regular security assessments. For critical environments, consider replacing affected devices with alternatives that follow secure firmware update practices.
