CVE-2023-28649 is a high-severity vulnerability found in the Snap One OvrC cloud platform, which is designed to centralize and manage various connected devices. This vulnerability allows an attacker to impersonate a hub, enabling them to send requests to claim devices that are already managed by another user. The OvrC cloud platform does not validate whether these devices are already claimed, which opens the door for malicious actors to take unauthorized control of devices.
The CVSS score of 8.6 indicates a high severity, categorizing it as a significant risk for organizations utilizing this platform. The vulnerability’s exploitability is considered high, which means that the potential for an attacker to successfully exploit this weakness is substantial. Organizations should take this threat seriously, as the implications of such an exploit could lead to unauthorized access and manipulation of critical devices.
Given the urgency of this vulnerability, organizations should prioritize patching immediately. The vulnerability was published on May 22, 2023, and has since been modified, indicating ongoing risk and the need for awareness and action from security teams.
With the potential for widespread impact, particularly in environments where the OvrC platform is integral to device management, it is crucial for organizations to evaluate their current deployments and implement necessary mitigations to safeguard against this vulnerability.
Vulnerability Details
The vulnerability affects the Hub in the Snap One OvrC cloud platform, which is utilized for managing connected devices. The official description reveals that an attacker could impersonate a hub and send requests to claim already claimed devices without proper validation of ownership or management status. The OvrC platform's failure to authenticate these requests enables this exploitation.
The vulnerability has been assigned a CVSS score of 8.6, indicating a high severity level with significant implications for availability, as the availability impact is rated high. The integrity impact has been rated as high as well, highlighting the potential for attackers to manipulate device management.
The affected product is the Snap One OvrC, specifically versions prior to 7.3.0. Organizations running these versions are vulnerable to this issue and should take immediate action to remediate it.
The vulnerability was published on May 22, 2023, and is classified under CWE-20 (Improper Input Validation) and CWE-413 (Addressing a Resource in an Incorrect Context).
Technical Analysis
The root cause of this vulnerability stems from the OvrC platform's failure to validate the ownership of claimed devices. An attacker can craft requests to claim devices that are already under the management of other users, thereby bypassing the intended security controls.
The attack vector for this vulnerability is network-based, allowing attackers to exploit it remotely without requiring physical access to the devices. The attack complexity is rated low, meaning that exploitation can be executed with minimal effort and no special privileges or user interaction.
The confidentiality impact is rated as none, indicating that sensitive data is not exposed through this vulnerability. However, the integrity impact is high, allowing attackers to take control of devices, which could lead to unauthorized actions being taken without the knowledge of legitimate users.
The availability impact is rated high, as the exploit could disrupt the normal functioning of claimed devices, potentially causing significant operational interruptions.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2023-28649 is significant. Organizations utilizing the Snap One OvrC cloud platform should recognize that the vulnerability exposes them to unauthorized access and control over critical devices. This situation presents a substantial blast radius, as compromised devices could be leveraged to launch further attacks against both the immediate network and connected systems.
Given the high CVSS score of 8.6, organizations must assess their current security posture and prioritize patching efforts to mitigate this vulnerability. The longer this vulnerability remains unaddressed, the greater the risk of exploitation, leading to potential operational disruptions and reputational damage.
Organizations should also consider implementing additional security measures, such as monitoring network traffic for signs of unauthorized requests and ensuring that proper authentication mechanisms are enforced for device management.
In summary, this vulnerability is a critical concern for organizations using the Snap One OvrC cloud platform, necessitating immediate attention and action.
