CVE-2014-1708 in Chrome OS
Summary
by MITRE
The boot implementation in Google Chrome OS before 33.0.1750.152 does not properly consider file persistence, which allows remote attackers to execute arbitrary code via unspecified vectors.

The vulnerability identified as CVE-2014-1708 resides within the boot implementation of Google Chrome OS, specifically affecting versions prior to 33.0.1750.152. This flaw represents a critical security weakness that undermines the integrity of the operating system's boot process, creating potential entry points for malicious actors to compromise affected systems. The issue stems from inadequate handling of file persistence mechanisms during the boot sequence, which should normally ensure that only legitimate and verified components are loaded and executed. This weakness allows attackers to manipulate the boot process through unspecified vectors, potentially leading to arbitrary code execution on affected Chrome OS devices.
The technical nature of this vulnerability aligns with CWE-284, which addresses improper access control in system components, and specifically relates to the boot process integrity controls. The flaw occurs because the Chrome OS boot implementation fails to properly validate or maintain the persistence of critical boot files, creating opportunities for attackers to substitute or modify these files before execution. This weakness manifests during the early boot stages when the system initializes its core components, particularly affecting the Trusted Boot process that should guarantee the authenticity and integrity of all boot-loaded modules. Attackers can exploit this vulnerability by leveraging the improper file persistence handling to inject malicious code that executes with elevated privileges during the boot sequence.
The operational impact of CVE-2014-1708 extends beyond simple code execution, as it fundamentally compromises the security model of Chrome OS devices. When successfully exploited, this vulnerability enables attackers to gain persistent access to affected systems, potentially leading to complete system compromise and data exfiltration. The attack surface is particularly concerning given that Chrome OS devices are commonly used in enterprise environments and by users who expect robust security protections. The unspecified vectors suggest that multiple attack paths may exist, making the vulnerability more difficult to defend against and potentially more widespread in its exploitation potential. This weakness essentially undermines the foundational security assumptions of the Chrome OS architecture, particularly the Trusted Boot mechanism that is designed to prevent unauthorized modifications to the system's core components.
Mitigation strategies for CVE-2014-1708 primarily focus on updating to the patched version of Chrome OS 33.0.1750.152 or later, which addresses the file persistence handling issues in the boot implementation. Organizations should prioritize immediate deployment of this security update across all affected Chrome OS devices to prevent exploitation. Additionally, implementing network monitoring solutions that can detect anomalous boot processes or unauthorized file modifications may provide supplementary protection. Security teams should also conduct comprehensive vulnerability assessments to identify any potential exploitation attempts and ensure that all Chrome OS devices are properly managed through secure update channels. The remediation process should include verification that the boot integrity checks are functioning correctly and that no unauthorized modifications have occurred during the update process. This vulnerability demonstrates the critical importance of maintaining robust boot security mechanisms and proper file integrity validation throughout the operating system lifecycle, aligning with ATT&CK technique T1068 which covers local privilege escalation through boot process manipulation.
