Cisco vManage Log4j Remote Code Execution Vulnerability Scanner

Cisco vManage is part of the Cisco SD-WAN solution, providing a centralized management interface that allows network administrators to configure, manage, and monitor the Cisco SD-WAN infrastructure. It is used by organizations to simplify the management of wide area networks, enhance bandwidth efficiency, and improve security. Cisco vManage offers a comprehensive dashboard for traffic management, policy administration, and the deployment of services and applications across the network. This platform is critical for enterprises that rely on Cisco's SD-WAN solutions to ensure high levels of network performance, reliability, and security.

This scanner targets a severe Remote Code Execution vulnerability within Cisco vManage, exploiting the Apache Log4j framework. The flaw allows unauthorized attackers to execute arbitrary code remotely, without needing authentication. This vulnerability is particularly dangerous because it can be exploited by simply sending malicious requests to the affected system, enabling attackers to potentially gain full control over the system, deploy malware, or steal sensitive information.

The vulnerability arises due to the way Cisco vManage processes input passed to the Log4j library. An attacker can exploit this by crafting malicious input that, when processed by the Log4j library within Cisco vManage, triggers the execution of arbitrary code. This attack is facilitated through the JNDI (Java Naming and Directory Interface) feature of Log4j, allowing the attacker to remotely execute code by referencing a malicious LDAP server. The attack vector typically involves sending a specially crafted request to the Cisco vManage interface, bypassing normal authentication mechanisms.

The exploitation of this vulnerability could lead to severe consequences, including unauthorized system access, execution of malware, data theft, and system compromise. For organizations using Cisco vManage, this could disrupt network operations, compromise sensitive information, and result in significant security and operational risks. The ability for attackers to execute arbitrary code remotely without authentication makes this vulnerability a critical threat.
