CVE-2024-31317 is classified as a high-severity vulnerability with a CVSS score of 7.8. This vulnerability allows code execution as any app via WRITE_SECURE_SETTINGS due to unsafe deserialization in multiple functions of ZygoteProcess.java. The exploitation of this vulnerability requires user execution privileges but does not require user interaction, which increases its risk profile significantly.
Organizations using affected versions of Google Android should prioritize patching immediately. The potential for local privilege escalation poses a significant risk to both users and system integrity. As exploitation is possible, the urgency for defenders to address this vulnerability cannot be overstated.
The vulnerability was published on July 9, 2024, and is known to be exploitable. Organizations must assess their exposure and implement the necessary security measures to protect against potential attacks.
Risk to organizations includes unauthorized code execution, leading to potential data breaches and compromise of sensitive information. Immediate action is essential to mitigate these risks.
In summary, CVE-2024-31317 represents a serious threat to Google Android users. Organizations should act swiftly to apply patches and ensure their systems are secured against this vulnerability.
Vulnerability Details
The CVE description indicates that the vulnerability arises from unsafe deserialization processes within the ZygoteProcess.java file. The affected versions of Android include 12.0, 12.1, 13.0, and 14.0, where the vulnerability can lead to a local escalation of privilege.
The CVSS score of 7.8 categorizes this vulnerability as high severity, indicating that it poses a significant risk due to its potential impacts on confidentiality, integrity, and availability.
The vulnerability has a CWE classification of CWE-502, which is related to deserialization of untrusted data.
Technical Analysis
The root cause of CVE-2024-31317 lies in the improper handling of data during the deserialization process, allowing an attacker to manipulate data structures and execute arbitrary code.
The attack vector is local, requiring a low level of complexity to exploit, as it does not necessitate user interaction. This makes it easier for attackers to exploit the vulnerability once they gain access to the device.
The privileges required for exploitation are low, which further increases the risk as many users may inadvertently execute malicious code without realizing it.
The impact of exploitation includes high confidentiality, integrity, and availability impacts, emphasizing the critical nature of this vulnerability.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2024-31317 is significant due to the local privilege escalation it enables. Attackers may leverage this vulnerability to execute unauthorized code, leading to potentially severe consequences for affected users.
This vulnerability matters to organizations as it could allow attackers to gain control over devices, access sensitive data, and disrupt services. The blast radius potential is large, as multiple versions of Android are affected, impacting a wide user base.
Given the CVSS score and the current exploit availability, organizations should prioritize remediation efforts based on the urgency of patching this vulnerability. The potential for exploitation and the impact on business operations necessitate immediate attention.
