Name of the Vulnerable Software and Affected Versions Android versions Android-13

Description The issue is related to a possible bypass of user-specified wifi encryption protocol due to improperly used crypto in the parseSecurityParamsFromXml function of XmlUtil.java. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

Recommendations For Android version Android-13, consider disabling the parseSecurityParamsFromXml function in XmlUtil.java as a temporary workaround until a patch is available. Restrict access to wifi encryption protocol settings to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
