Remote Code Execution in Google Chrome V8 complex species handling

IdentifiersCVE-2017-5030CWE-20

CVE-2017-5030 is a remote code execution vulnerability in the V8 JavaScript engine used by Google Chrome. According to the provided content, the issue is caused by incorrect handling of complex species in V8 in Chrome versions prior to 57.0.2987.98 for Linux, Windows, and Mac, and prior to 57.0.2987.108 for Android. A remote attacker could trigger the flaw by luring a victim to a crafted HTML page, causing unsafe processing in V8 that could lead to arbitrary code execution within the browser context.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows a remote attacker to execute arbitrary code on the target system via a crafted HTML page. In practical terms, this can result in compromise of the Chrome renderer process and may enable delivery of additional malware or spyware. The supplied context specifically notes its use as part of Android exploitation chains in targeted mobile espionage operations.

Mitigation

If you can’t patch tonight, do this now.

Until patching is completed, reduce exposure by restricting use of outdated Chrome versions, limiting access to untrusted or attacker-controlled web content, and using mobile device and browser update policies to ensure timely deployment of Chrome security fixes. In enterprise environments, application allowlisting, browser isolation, and detection of exploit-delivery links can reduce risk, but patching is the primary mitigation.

Remediation

Patch, then assume compromise.

Upgrade Google Chrome to version 57.0.2987.98 or later on Linux, Windows, and Mac, and to 57.0.2987.108 or later on Android. Apply vendor security updates to ensure the vulnerable V8 implementation is replaced with a patched version.
