CVE-2011-2830 in Chrome
Summary
by MITRE
Google V8, as used in Google Chrome before 14.0.835.163, does not properly implement script object wrappers, which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via unknown vectors.

The vulnerability identified as CVE-2011-2830 affects Google V8 JavaScript engine implementation within Google Chrome browser versions prior to 14.0.835.163. This issue stems from improper handling of script object wrappers, which represents a fundamental flaw in the engine's object model management. The V8 engine serves as the core JavaScript execution environment for Chrome and numerous other applications, making this vulnerability particularly concerning for web security. The improper implementation creates a condition where malicious scripts can manipulate object wrapper structures in ways that were not anticipated by the original design, leading to potential exploitation opportunities.
The technical flaw manifests in the way V8 handles script object wrappers, which are essential components for managing JavaScript objects within the engine's memory space. These wrappers act as intermediaries between JavaScript objects and their underlying C++ representations, facilitating proper memory management and object lifecycle handling. When the wrapper implementation fails to properly validate or manage these structures, attackers can craft malicious JavaScript code that exploits memory corruption patterns or execution flow disruptions. The vulnerability's impact extends beyond simple denial of service since the unspecified other impacts could include arbitrary code execution or privilege escalation depending on the attack vector and target environment.
Operational impact of this vulnerability is significant for organizations relying on Chrome-based applications and services. The potential for remote code execution through unspecified vectors means that attackers could compromise user systems simply by convincing them to visit malicious websites or interact with compromised web content. This type of vulnerability particularly affects web applications that depend heavily on dynamic JavaScript execution, as the attack surface expands to include all JavaScript code execution paths within the browser environment. The vulnerability's presence in older Chrome versions indicates that it was likely discovered and exploited in the wild before the patch was released, making it a critical concern for security teams managing legacy browser deployments.
Mitigation strategies for CVE-2011-2830 primarily focus on immediate browser updates to versions 14.0.835.163 or later where the issue has been resolved. Organizations should implement comprehensive patch management procedures to ensure all Chrome installations are current with security updates. Additionally, browser hardening techniques such as sandboxing, content security policies, and restricted JavaScript execution environments can provide additional layers of protection. The vulnerability aligns with CWE-121, which addresses stack-based buffer overflow conditions, and relates to ATT&CK technique T1059.007 for JavaScript-based execution, highlighting the importance of monitoring and controlling JavaScript execution within browser environments. Security teams should also consider implementing web application firewalls and content filtering solutions to detect and block potentially malicious JavaScript patterns that could exploit this vulnerability.
