CVE-2023-40113 is a medium-severity vulnerability affecting Google Android that enables apps to access cross-user message data due to a missing permission check. This vulnerability allows for local information disclosure without requiring additional execution privileges, and importantly, user interaction is not necessary for exploitation. With a CVSS score of 5.5, the risk to organizations includes potential unauthorized access to sensitive data, which can have serious implications for user privacy and data integrity.
Due to the nature of this vulnerability, organizations must prioritize patching immediately. The potential for exploitation is significant, especially in environments where sensitive information is routinely accessed. The affected Android versions include 11.0, 12.0, 12.1, and 13.0, which further underscores the urgency for defenders to implement remediation strategies.
As of now, there have been no confirmed public exploits or known exploitation in the wild for this vulnerability. However, given the medium severity classification and the high impact on confidentiality, organizations should remain vigilant and proactive in their security posture.
In conclusion, CVE-2023-40113 presents a notable risk to organizations using the affected versions of Android. Immediate attention to patching and potential workarounds is necessary to mitigate the risk of unauthorized information access.
Vulnerability Details
The official CVE description notes that in multiple locations, there is a possible way for apps to access cross-user message data due to a missing permission check. The vulnerability is classified under CWE-862, indicating issues with permission management. The CVSS score of 5.5, classified as medium severity, highlights the importance of addressing this vulnerability in a timely manner.
Technical Analysis
The root cause of CVE-2023-40113 stems from a lack of proper permission checks that allow applications to access sensitive message data across different user accounts. The attack vector is local, meaning that an attacker must have physical or logical access to a device with an affected version of Android. The attack complexity is low, and only low privileges are required to exploit this vulnerability. Notably, user interaction is not needed for exploitation, further increasing the risk.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2023-40113 is significant. Organizations that deploy the affected Android versions could face unauthorized access to confidential messages, leading to potential data breaches and loss of user trust. The blast radius of such an exploit could extend beyond individual users, impacting organizational reputation and compliance with data protection regulations.
Given the CVSS score of 5.5 and the absence of confirmed exploits, organizations should assess their environments and prioritize patching as part of their immediate security measures. The vulnerability's medium severity indicates that while it may not be critical, it still requires attention to prevent potential exploitation.
