CVE-2019-5825 is classified as a medium-severity vulnerability affecting Google Chrome versions prior to 73.0.3683.86. This vulnerability allows out-of-bounds write in JavaScript, which could potentially lead to heap corruption. The exploitation risk is particularly concerning as it could allow a remote attacker to execute arbitrary code via a specially crafted HTML page. Given the widespread use of Google Chrome, the potential impact on users is significant.
The CVSS score of 6.5 indicates a medium severity, with noteworthy implications for availability. Organizations must prioritize addressing this vulnerability to minimize risk exposure. The urgency for defenders is heightened, as the attack vector is network-based, and user interaction is required to trigger the vulnerability.
It is crucial for organizations to apply the latest updates to Google Chrome to mitigate the risks associated with CVE-2019-5825. Without prompt action, users remain vulnerable to potential exploitation.
As of now, this vulnerability is known to have an associated exploit, which further emphasizes the need for immediate remediation. Security teams should be vigilant and monitor their environments for any signs of exploitation.
Vulnerability Details
The official description of CVE-2019-5825 states that it involves an out-of-bounds write in JavaScript in Google Chrome prior to version 73.0.3683.86. This vulnerability could allow a remote attacker to exploit heap corruption via a crafted HTML page. The vulnerability is classified under CWE-787 and has a CVSS score of 6.5, indicating medium severity.
The affected product is Google Chrome, and its configurations are vulnerable if they are versions prior to 73.0.3683.86. The vulnerability was published on November 25, 2019, and it is essential for users to upgrade to the patched version to ensure security.
Technical Analysis
The root cause of CVE-2019-5825 is an out-of-bounds write, which can occur when the JavaScript engine processes certain inputs incorrectly. This vulnerability exposes the system to heap corruption, which can compromise the stability and integrity of the application.
The attack vector is network-based, meaning that attackers can exploit this vulnerability remotely. The attack complexity is low, and no privileges are required for exploitation. However, user interaction is needed, as the victim must visit a malicious web page to trigger the vulnerability.
In terms of impact, the confidentiality and integrity are not affected, but the availability is significantly compromised, as successful exploitation can lead to application crashes or unexpected behavior.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2019-5825 is considerable. Organizations using Google Chrome in their environments must understand the potential for exploitation. Given the high availability impact, organizations could face significant disruptions if an attacker successfully exploits this vulnerability.
The vulnerability has been included in the Known Exploited Vulnerabilities (KEV) catalog, reinforcing its urgency. Security teams should assess the blast radius and ensure that all affected systems are patched promptly.
The CVSS score of 6.5 indicates a moderate level of urgency; however, given the exploit availability and the potential impact, organizations should treat this vulnerability as a critical priority.
