The vulnerability CVE-2015-4272 represents a critical cross-site scripting flaw discovered in Cisco Unified Communications Manager version 10.5(2.10000.5) affecting the ccmivr page component. This issue falls under the CWE-79 category of Cross-Site Scripting, which is one of the most prevalent web application security vulnerabilities identified by the CWE organization. The vulnerability specifically impacts the interactive voice response functionality within Cisco's unified communications platform, creating a pathway for remote attackers to execute malicious code through web-based interfaces.
The technical exploitation of this vulnerability occurs through the manipulation of crafted parameters within the ccmivr page, which serves as an interface for managing voice response systems. Attackers can inject arbitrary web scripts or HTML code that gets executed when legitimate users access the affected page. This type of vulnerability enables attackers to bypass normal access controls and potentially gain unauthorized access to user sessions, steal sensitive information, or redirect users to malicious websites. The flaw exists due to insufficient input validation and output encoding mechanisms within the web application's parameter handling logic.
From an operational impact perspective, this vulnerability poses significant risks to organizations relying on Cisco Unified Communications Manager for their voice communication infrastructure. The remote exploitation capability means attackers can target users from anywhere on the internet without requiring physical access to the network. This vulnerability could lead to unauthorized access to voice communication systems, potential eavesdropping on sensitive conversations, session hijacking, and the possibility of using the compromised system as a launch point for further attacks within the network. The vulnerability affects the core communication infrastructure, potentially disrupting business operations and compromising sensitive corporate communications.
The attack surface for this vulnerability extends beyond simple script injection, as it can be leveraged in conjunction with other techniques to create more sophisticated attack vectors. According to ATT&CK framework, this vulnerability maps to T1566 (Phishing) and T1059 (Command and Scripting Interpreter) techniques, as attackers can use the XSS capability to deliver malicious payloads that execute commands on victim systems. Organizations should implement multiple layers of defense including web application firewalls, input validation controls, and regular security assessments to protect against such vulnerabilities. The remediation typically involves applying Cisco's official security patches and updates, implementing proper parameter sanitization, and conducting regular vulnerability scanning of the unified communications infrastructure to prevent exploitation attempts.
