In WorkSource, there is a possible parcel mismatch. This vulnerability allows for local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. The CVSS score of 7.8 indicates a high severity, reflecting the potential impact on confidentiality, integrity, and availability.
Risk to organizations includes unauthorized access to sensitive data and potential system integrity compromise. Given the local attack vector, the risk is particularly pertinent for environments where Android devices are used for critical operations. Organizations should prioritize patching immediately.
As of now, this vulnerability has been included in the Known Exploited Vulnerabilities (KEV) catalog, highlighting its critical nature. Security teams must take immediate action to apply necessary updates as per the vendor's instructions.
The following sections will detail the vulnerability specifics, technical analysis, risk assessment, and recommended mitigations.
Vulnerability Details
This vulnerability affects Android versions 11, 12, 12L, and 13. It has been classified as CWE-295, indicating a potential issue related to improper certificate validation. The vulnerability was published on March 24, 2023, and has since been analyzed for its impact.
Technical Analysis
The root cause of this vulnerability stems from a parcel mismatch in the WorkSource component. This issue allows an attacker with low privileges to escalate their access without requiring user interaction. The attack complexity is low, making it easier for potential exploiters.
The attack vector is classified as local, meaning that the attacker must have physical access to the device. The attack would not require high privileges, and user interaction is not necessary, which broadens the scope of potential exploitation. The impacts on confidentiality, integrity, and availability are all rated as high, indicating significant risks.
Risk & Impact Analysis
The potential for local privilege escalation represents a critical risk for organizations relying on Android devices for sensitive operations. The blast radius could encompass critical data exposure and unauthorized modifications to system integrity.
Given the vulnerability's inclusion in the KEV catalog and its high CVSS score, organizations should assess their exposure and prioritize remediation efforts based on their operational context.
