CVE-2010-3279 in CCAgent
Summary
by MITRE
The default configuration of the CCAgent option before 9.0.8.4 in the management server (aka TSA) component in Alcatel-Lucent OmniTouch Contact Center Standard Edition enables maintenance access, which allows remote attackers to monitor or reconfigure Contact Center operations via vectors involving TSA_maintenance.exe.

The vulnerability identified as CVE-2010-3279 represents a critical security flaw in the Alcatel-Lucent OmniTouch Contact Center Standard Edition management server component. This issue affects versions prior to 9.0.8.4 and stems from insecure default configurations that inadvertently expose maintenance access capabilities. The vulnerability specifically impacts the CCAgent option within the TSA (TSA_maintenance.exe) component, creating a pathway for unauthorized remote access to critical contact center operations.
The technical flaw manifests through the default configuration of the CCAgent option which fails to properly restrict access to maintenance functions. This misconfiguration allows remote attackers to establish connections and perform operations that should be restricted to authorized administrators only. The vulnerability enables attackers to monitor ongoing contact center activities and reconfigure operational parameters, effectively providing them with administrative privileges over the system without requiring legitimate authentication credentials. This represents a classic case of insufficient access control where default settings fail to implement proper security boundaries.
The operational impact of this vulnerability extends beyond simple unauthorized access, as it allows attackers to manipulate critical business operations in real-time. Remote monitoring capabilities could expose sensitive customer data, call recordings, and operational metrics to unauthorized parties, while the reconfiguration functionality could disrupt service delivery, alter call routing, or disable critical system components. The attack surface is particularly concerning given that the vulnerability exists in the management server component, which typically holds the highest level of system privileges and controls core operational parameters of the contact center infrastructure.
This vulnerability aligns with CWE-284, which addresses inadequate access control mechanisms, and maps to several ATT&CK techniques including T1078 for valid accounts and T1566 for social engineering through access to legitimate credentials. The risk is compounded by the fact that the vulnerability exists in default configurations, meaning that organizations are potentially exposed without any explicit action on their part. The attack vector specifically involves exploiting the TSA_maintenance.exe component which suggests the vulnerability may be present in the system's management interface or administrative console functionality.
Organizations should immediately implement mitigations including updating to version 9.0.8.4 or later, which contains the necessary security patches to address the insecure default configurations. Network segmentation should be implemented to isolate the management server from untrusted networks, and access controls should be manually configured to restrict maintenance access to authorized personnel only. Additionally, regular security audits should verify that default configurations have not been inadvertently modified to reintroduce the vulnerability. The remediation process should include comprehensive testing to ensure that maintenance access is properly restricted while maintaining legitimate administrative functionality for authorized users.
