Android Framework Privilege Escalation Vulnerability
Android Framework contains an unspecified vulnerability that allows for privilege escalation.
A local attacker, with a low-privilege account, can achieve full data confidentiality loss, arbitrary modification of data, complete denial of service or system unavailability. Federal agencies are required to remediate by 2024-11-28 under CISA BOD 22-01.
This is a Software Vulnerability (CWE-176) (CWE-176) vulnerability in Android Framework. In shouldHideDocument of ExternalStorageProvider.java, there is a possible bypass of a file path filter designed to prevent access to sensitive directories due to incorrect unicode normalization. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is needed for exploitation. Exploitation requires local access, low attack complexity, a low-privilege authenticated account, and user interaction required.
Probably yes if any of these apply:
CISA added this CVE to the Known Exploited Vulnerabilities catalog on 2024-11-07 based on evidence of active exploitation in the wild. Federal agencies required to remediate by 2024-11-28.
