CVE-2024-55024 is an authentication bypass vulnerability identified in the authorization mechanism of the Weintek cMT-3072XH2 easyweb v2.1.53, OS version 20231011. The flaw allows attackers who have access to service accounts—accounts typically with limited privileges—to bypass normal authorization checks and perform administrative actions on the device. This vulnerability is classified under CWE-693, which relates to protection mechanisms that are insufficient or improperly implemented. The vulnerability does not require user interaction and can be exploited remotely over the network, given that the attacker has at least service account credentials or access. The CVSS v3.1 base score of 8.8 indicates a high severity, with attack vector being network-based, low attack complexity, privileges required being low, and no user interaction needed. The impact on confidentiality, integrity, and availability is high, as administrative actions can compromise all three aspects. No patches or fixes have been published at the time of disclosure, and no known exploits have been observed in the wild. The vulnerability poses a significant risk to industrial control systems and environments where Weintek cMT-3072XH2 devices are deployed, potentially allowing attackers to take full control of the device and disrupt operations or steal sensitive information.

The vulnerability allows unauthorized privilege escalation from service accounts to full administrative control, threatening the confidentiality, integrity, and availability of affected devices. Attackers could manipulate device configurations, disrupt industrial processes, or exfiltrate sensitive operational data. This could lead to operational downtime, safety hazards, and financial losses, especially in critical infrastructure sectors such as manufacturing, energy, and utilities. Since the device is used in industrial automation, exploitation could have cascading effects on production lines or critical services. The lack of patches increases the window of exposure, and the remote exploitability without user interaction makes it easier for attackers to compromise systems. Organizations worldwide using these devices face potential operational disruption and data breaches if the vulnerability is exploited.

Until an official patch is released, organizations should implement strict network segmentation to isolate Weintek cMT-3072XH2 devices from untrusted networks and limit access to only trusted service accounts. Employ strong authentication and monitor service account usage for anomalous activities. Use network intrusion detection systems (NIDS) to detect unusual administrative commands or access patterns. Disable or restrict remote access to the device’s management interfaces where possible. Regularly audit device configurations and logs for signs of unauthorized administrative actions. Engage with Weintek support for any available workarounds or interim security advisories. Prepare incident response plans specific to industrial control system compromises. Once patches become available, prioritize immediate deployment to remediate the vulnerability.
