CVE-2023-51570 in ViewPower Pro
Summary
by MITRE • 04/02/2024
Voltronic Power ViewPower Pro Deserialization of Untrusted Data Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Voltronic Power ViewPower Pro. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the RMI interface, which listens on TCP port 41009 by default. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this vulnerability to execute code in the context of SYSTEM. Was ZDI-CAN-21012.

The CVE-2023-51570 vulnerability represents a critical deserialization flaw in Voltronic Power ViewPower Pro software that exposes systems to remote code execution attacks. This vulnerability specifically targets the Remote Method Invocation (RMI) interface that operates on TCP port 41009, making it accessible to attackers without requiring any authentication credentials. The flaw stems from insufficient input validation mechanisms within the deserialization process, creating an avenue for malicious actors to inject crafted data that gets processed by the application. This type of vulnerability falls under CWE-502 which specifically addresses deserialization of untrusted data, a well-known attack vector that has been exploited in numerous high-profile security incidents across various platforms and applications.
The technical implementation of this vulnerability allows attackers to leverage the RMI interface to send malicious serialized objects that get deserialized by the vulnerable application. When the application processes these untrusted inputs without proper sanitization or validation, it creates an execution environment where arbitrary code can be injected and executed with the privileges of the SYSTEM account. This privilege escalation capability significantly amplifies the impact of the vulnerability, as successful exploitation provides attackers with complete control over the affected system. The default listening port of 41009 makes this vulnerability particularly dangerous as it reduces the attack surface complexity for threat actors who can directly target this specific port without needing to discover or guess service endpoints. The vulnerability's classification as a remote code execution issue places it within the ATT&CK framework's T1059.007 technique for command and script injection, potentially enabling attackers to establish persistent access and conduct further reconnaissance or lateral movement within compromised networks.
The operational impact of CVE-2023-51570 extends beyond immediate system compromise, as it can facilitate broader security breaches within organizations that rely on Voltronic Power ViewPower Pro for power management and monitoring. Systems running this vulnerable software may become entry points for attackers to infiltrate larger network infrastructures, especially in environments where power monitoring systems are integrated with critical operational technology networks. The lack of authentication requirements means that this vulnerability can be exploited through automated scanning tools, making it particularly dangerous in publicly accessible environments. Organizations should consider implementing network segmentation strategies to isolate systems running vulnerable versions of ViewPower Pro, while also monitoring for unusual network activity on port 41009 that might indicate exploitation attempts. The vulnerability's nature suggests that mitigation efforts should focus on both network-level protections through firewall rules that restrict access to the RMI port and application-level patches that address the deserialization validation issues. Given that this vulnerability was previously identified as ZDI-CAN-21012, organizations should also consider implementing additional monitoring for similar patterns of exploitation that might target other components of the Voltronic Power ecosystem.
