CVE-2022-26479 in EagleEye Director II
Summary
by MITRE • 07/18/2022
An issue was discovered in Poly EagleEye Director II before 2.2.2.1. Existence of a certain file (which can be created via an rsync backdoor) causes all API calls to execute as admin without authentication.

The vulnerability identified as CVE-2022-26479 affects the Poly EagleEye Director II video surveillance management system prior to version 2.2.2.1. This critical security flaw stems from improper access control mechanisms within the application's API authentication system. The vulnerability manifests when a specific malicious file is present on the system, which can be introduced through an rsync backdoor mechanism, creating a persistent threat vector that undermines the system's security posture.
The technical exploitation of this vulnerability occurs through a file-based attack vector that bypasses standard authentication mechanisms. When the designated malicious file exists within the system's file structure, it triggers a privilege escalation condition where all subsequent API calls automatically execute with administrative privileges regardless of the caller's actual authentication status. This represents a fundamental failure in the application's authorization model, where the system fails to properly validate user credentials or session tokens before granting elevated access rights. The flaw operates at the application layer and demonstrates a classic case of insecure direct object reference combined with privilege escalation vulnerabilities.
The operational impact of this vulnerability is severe and far-reaching for organizations relying on the Poly EagleEye Director II system for video surveillance and security monitoring. An attacker who can place the malicious file on the system gains complete administrative control over the entire surveillance infrastructure, including the ability to modify camera configurations, access live and recorded video feeds, manipulate system settings, and potentially exfiltrate sensitive security data. This vulnerability effectively nullifies all authentication controls and creates a persistent backdoor that remains active until the malicious file is removed or the system is patched. The implications extend beyond simple unauthorized access to include potential data breaches, system compromise, and disruption of critical security operations that organizations depend upon for physical security monitoring.
Organizations should immediately implement mitigation strategies including applying the vendor-provided patch to version 2.2.2.1 or later, conducting thorough security assessments to identify and remove any existing malicious files, and implementing network segmentation to limit access to the affected system. System administrators should also monitor for unauthorized file modifications and establish robust file integrity monitoring procedures. This vulnerability aligns with CWE-284, which addresses improper access control, and maps to attack techniques in the ATT&CK framework under privilege escalation and persistence tactics. The rsync backdoor component specifically relates to the ATT&CK technique T1105 for remote access tools and T1078 for valid accounts, demonstrating how multiple attack vectors can combine to create a comprehensive compromise scenario that undermines the fundamental security architecture of the targeted system.
