The vulnerability identified as CVE-2015-7275 affects Dell Integrated Remote Access Controller (iDRAC) versions 6 before 2.85 and 7/8 before 2.30.30.30, representing a cross-site scripting flaw that poses significant security risks to enterprise server management systems. This vulnerability resides within the web-based management interface of Dell's remote access controllers, which are critical components for system administrators to monitor and control servers remotely. The iDRAC technology provides out-of-band management capabilities, allowing administrators to access server consoles, configure hardware settings, and monitor system health even when the primary operating system is unresponsive or offline.
The technical implementation of this cross-site scripting vulnerability stems from insufficient input validation and output encoding within the iDRAC web interface components. Attackers can exploit this weakness by injecting malicious script code into parameters that are subsequently rendered in the web application's response without proper sanitization. This flaw specifically affects user-controllable input fields within the management interface, where submitted data is not adequately escaped or filtered before being displayed to authenticated users. The vulnerability falls under the Common Weakness Enumeration category CWE-79, which defines cross-site scripting as a critical weakness that allows attackers to execute scripts in the context of a victim's browser session.
The operational impact of this vulnerability extends beyond simple data theft or session hijacking, as it can enable attackers to compromise the entire remote management infrastructure of affected Dell servers. When exploited, the XSS vulnerability allows malicious actors to perform actions such as stealing administrator session cookies, modifying management interface settings, or redirecting users to malicious websites. The severity is particularly concerning given that iDRAC systems are often deployed in critical enterprise environments where they maintain persistent access to sensitive server infrastructure. Attackers could leverage this vulnerability to gain unauthorized access to server management functions, potentially leading to complete system compromise or unauthorized modifications to server configurations.
Security professionals should recognize this vulnerability as part of the broader ATT&CK framework's technique T1071.004, which covers application layer protocol usage for command and control communications. The affected Dell iDRAC implementations represent a prime target for attackers seeking persistent access to enterprise networks, as these controllers often maintain long-lived connections and elevated privileges within server environments. Organizations should prioritize immediate remediation through firmware updates provided by Dell, as the vendor released patches specifically addressing this XSS vulnerability in versions 2.85 and 2.30.30.30 respectively. Additional mitigations include implementing network segmentation to isolate management interfaces, enforcing strict access controls, and monitoring for suspicious activity in management console logs. The vulnerability demonstrates the critical importance of secure web application development practices and proper input validation in enterprise management systems that handle sensitive operational data.
