Name of the Vulnerable Software and Affected Versions Android versions Android-12

Description The issue is related to a tapjacking/overlay attack in the onCreate method of RequestManageCredentials.java, allowing a third-party app to install certificates without user approval. This could lead to local escalation of privilege, requiring User execution privileges and user interaction for exploitation.

Recommendations For Android version Android-12, consider restricting access to the RequestManageCredentials.java module to minimize the risk of exploitation until a patch is available. As a temporary workaround, avoid using the onCreate method of RequestManageCredentials.java until the issue is resolved.
