This vulnerability resides in Cisco CallManager software versions prior to specific security patches, representing a critical privilege escalation flaw that enables authenticated attackers to elevate their access rights from read-only to full administrative privileges. The vulnerability manifests through a crafted URL manipulation technique that exploits weaknesses in the web-based administrative interface of the system.
The technical flaw involves improper access control mechanisms within the CCMAdmin web page implementation, where the system fails to properly validate user permissions when processing specific URL parameters. This allows an attacker with read-only administrative credentials to manipulate URL parameters that should be restricted to full administrative users, effectively bypassing authentication checks and gaining complete control over the CallManager system. The vulnerability specifically affects multiple major versions including 3.2 and earlier, 3.3 before 3.3(5)SR1, 4.0 before 4.0(2a)SR2c, and 4.1 before 4.1(3)SR2, indicating a widespread issue across the product line.
The operational impact of this vulnerability is severe as it provides attackers with complete administrative control over the voice communication infrastructure, potentially enabling them to modify call routing, access sensitive communication data, manipulate user accounts, and disrupt business operations. This privilege escalation allows for unauthorized access to the entire CallManager administrative interface, including capabilities to add or remove users, modify system configurations, and potentially intercept or manipulate voice communications. The vulnerability is particularly dangerous because it requires only read-only administrative access to exploit, making it accessible to users who should not have elevated privileges.
Organizations should immediately implement mitigations including applying the relevant security patches released by Cisco for the affected versions, implementing network segmentation to restrict access to the CallManager administrative interfaces, and conducting thorough access control reviews to ensure proper privilege allocation. The vulnerability aligns with CWE-284 which addresses improper access control, and represents a significant concern for the ATT&CK framework under privilege escalation techniques. Organizations should also consider implementing additional monitoring and logging of administrative activities to detect potential exploitation attempts, as well as establishing robust change management processes to prevent unauthorized modifications to critical voice infrastructure components.
