Cisco Unified Communications Remote Code Execution Vulnerability Scanner

Cisco Unified Communications systems are utilized worldwide by businesses for integrated voice, video, data, and mobile applications on fixed and mobile networks. These systems allow organizations to communicate more effectively, helping to increase their productivity. They support a wide range of communication tools such as voice and video calling, voice messaging, video conferencing, and mobility features. Cisco Unified Communications is designed to support large-scale enterprise communications across multiple geographic locations. By integrating with various applications and systems, it enables a unified user experience for collaboration across industries.

This scanner detects a critical Remote Code Execution (RCE) vulnerability within the Cisco Unified Communications system, specifically exploiting the Apache Log4j framework. An attacker could remotely execute arbitrary code without requiring any user credentials, leading to unauthorized access and control over the affected system. This vulnerability poses a severe security risk, as it could allow attackers to deploy malware, steal sensitive information, modify data, or gain complete system control.

The vulnerability is exploited through crafted malicious input to the Log4j logging framework used within Cisco Unified Communications. By sending a specially crafted request to the system, an attacker can leverage the JNDI (Java Naming and Directory Interface) features of Log4j to execute arbitrary code remotely. This exploit bypasses authentication mechanisms and does not require any user interaction, making it particularly dangerous and easy to exploit. The endpoint and parameters involved in this vulnerability are primarily associated with authentication mechanisms within the system, such as the login process.

If exploited, this vulnerability could have severe implications, including the execution of malicious software on the system, theft of sensitive information, unauthorized data alteration, and complete control over the compromised system. This could result in significant operational disruptions, financial losses, and damage to the organization's reputation. Additionally, it could lead to further network infiltration and the spread of malware to other systems connected to the affected network.
