The vulnerability identified as CVE-2015-7274 affects Dell Integrated Remote Access Controller version 6 prior to 2.80, representing a critical security flaw that enables remote attackers to execute arbitrary administrative HTTP commands through the iDRAC interface. This vulnerability resides within Dell's remote management infrastructure, specifically targeting the administrative HTTP protocol implementation that governs remote access and system management operations. The issue stems from insufficient input validation and authentication mechanisms within the iDRAC6 controller's web interface, creating an attack surface that allows unauthorized command execution without proper authorization.
The technical flaw manifests through improper sanitization of HTTP request parameters and inadequate access controls within the iDRAC6 management interface. Attackers can exploit this weakness by crafting malicious HTTP requests that bypass authentication mechanisms and execute administrative commands directly on the target system. The vulnerability specifically affects the web-based management interface of the iDRAC6 controller, which provides remote access capabilities for server administration and monitoring. This flaw operates at the application layer of the network stack, leveraging the HTTP protocol to deliver malicious payloads that can manipulate system configurations, access sensitive data, and potentially gain full administrative control over the managed server.
The operational impact of CVE-2015-7274 is severe and far-reaching, as it allows attackers to compromise entire server management infrastructures without requiring physical access or legitimate credentials. Organizations utilizing affected Dell iDRAC6 systems face significant risks including unauthorized system modifications, data exfiltration, and potential lateral movement within network environments. The vulnerability enables attackers to perform actions such as changing administrator passwords, modifying system configurations, accessing server logs, and potentially establishing persistent backdoors. This represents a critical escalation of privileges vulnerability that directly violates the principle of least privilege and can lead to complete system compromise. The attack vector is particularly concerning as it requires only network connectivity to the iDRAC6 management interface, making it accessible from anywhere on the internet.
Mitigation strategies for CVE-2015-7274 primarily involve applying the official Dell security patches and firmware updates that address the authentication and input validation flaws within the iDRAC6 controller. Organizations should immediately upgrade to iDRAC6 version 2.80 or later, which includes proper input sanitization and enhanced authentication mechanisms. Network segmentation and access control measures should be implemented to restrict access to iDRAC management interfaces, limiting connections to trusted networks and implementing strong firewall rules. Additionally, organizations should disable unnecessary management services, implement strong password policies, and regularly audit access logs for suspicious activities. This vulnerability aligns with CWE-20, representing a weakness in input validation, and maps to ATT&CK technique T1078 for valid accounts and T1059 for command and scripting interpreter, highlighting the multi-faceted nature of the attack surface and the need for comprehensive security controls.
