CVE-2023-2464 is a medium-severity vulnerability affecting Google Chrome versions prior to 113.0.5672.63. This vulnerability allows an attacker who convinces a user to install a malicious extension to perform an origin spoof in the security UI via a crafted HTML page. The risk to organizations includes potential unauthorized actions being taken in the context of the user’s browser environment, leading to compromised user data or actions.
Given the nature of this vulnerability, it is critical for organizations to understand the implications. The CVSS score of 4.3 indicates a medium level of severity, emphasizing the need for prompt action. Users must be aware of the risks associated with installing extensions from untrusted sources.
The vulnerability's exploitation status is currently unknown, as no public exploit has been confirmed. However, organizations should prioritize patching this vulnerability to safeguard against potential attacks.
Organizations should prioritize patching immediately. Users should be encouraged to regularly update their browsers and avoid installing extensions from unverified sources to mitigate the risk associated with this vulnerability.
Vulnerability Details
The vulnerability is classified as inappropriate implementation in the PictureInPicture feature of Google Chrome. It has a CVSS score of 4.3, with the following characteristics: • Attack Vector: Network • Attack Complexity: Low • Privileges Required: None • User Interaction: Required • Confidentiality Impact: None • Integrity Impact: Low • Availability Impact: None
The vulnerability affects all versions of Google Chrome prior to the patched version, specifically versions before 113.0.5672.63, along with various Fedora and Debian systems.
Technical Analysis
The root cause of CVE-2023-2464 lies in the improper implementation of the PictureInPicture feature within Chrome. This flaw allows an attacker to leverage social engineering tactics to convince a victim to install a malicious extension. Once installed, the extension can manipulate the browser's security UI, potentially leading to an origin spoof.
The attack vector is network-based; hence, the attacker does not require physical access to the victim's machine. The attack complexity is classified as low, as it primarily hinges on user interaction to install the malicious extension. No elevated privileges are needed, making this vulnerability particularly concerning.
The impacts of this vulnerability manifest through low integrity effects where unauthorized actions can be executed in the context of the user's session. However, confidentiality and availability impacts are deemed minimal.
Risk & Impact Analysis
Real-world deployment of this vulnerability poses significant risks to organizations. If exploited, attackers could manipulate the security UI to execute unauthorized actions, potentially leading to data breaches or further exploitation of the user's environment. The blast radius can vary depending on the number of users who fall victim to the attack.
With a CVSS score of 4.3, organizations should address this vulnerability in their priority patch cycle. Regular monitoring and user education on the risks of malicious extensions can further help mitigate the impact.

Affected Versions
The affected versions include Google Chrome versions prior to 113.0.5672.63, as well as Fedora versions 36, 37, and 38, and Debian Linux version 11.0. Organizations should ensure that they are running updated versions to mitigate this risk.
Mitigation & Remediation
To mitigate this vulnerability, organizations should ensure that they update Google Chrome to version 113.0.5672.63 or later. Additionally, implementing browser extension policies that restrict the installation of unverified extensions can help reduce exposure to similar risks in the future. Regular audits of installed extensions can further enhance security.
For further guidance on security practices, organizations may refer to relevant resources such as application security assessments to evaluate their preventive measures.
Detection Guidance
Organizations should monitor their systems for unusual extension installations or unexpected browser behavior, as these may indicate attempts to exploit vulnerabilities. Behavioral anomalies in user actions and changes in permissions for browser extensions are critical indicators to watch.
AppSecure Threat Intelligence Insight
CVE-2023-2464 represents a concerning trend of browser vulnerabilities being exploited through social engineering tactics. Organizations should proactively address vulnerabilities and educate users about the risks associated with installing unverified extensions. Continuous security testing, such as continuous penetration testing, can help identify weaknesses before they are exploited.
To further enhance their security posture, organizations can benefit from an established red teaming service to simulate attacks and strengthen defenses.
Finally, integrating a penetration testing service can assist organizations in regularly evaluating their security measures against evolving threats.
