CVE-2022-20501: Elevation of privilege in Android
In onCreate of EnableAccountPreferenceActivity.java, there is a possible way to mislead the user into enabling a malicious phone account due to a tapjacking/overlay attack. This could lead to local escalation of privilege with User execution privileges needed. User interaction is needed for exploitation.Product: AndroidVersions: Android-10 Android-11 Android-12 Android-12L Android-13Android ID: A-246933359
AI Analysis
Technical Summary
CVE-2022-20501 is a high-severity elevation of privilege vulnerability affecting multiple versions of the Android operating system, specifically Android 10 through Android 13, including Android 12L. The vulnerability arises in the onCreate method of the EnableAccountPreferenceActivity.java component, where a tapjacking or overlay attack can mislead the user into enabling a malicious phone account. Tapjacking involves an attacker placing a transparent or opaque overlay over a legitimate app interface, tricking the user into interacting with the overlay instead of the intended UI elements. In this case, the overlay can cause the user to unknowingly grant elevated privileges to a malicious phone account, effectively escalating privileges locally on the device. Exploitation requires user interaction, specifically the user tapping on the interface elements under the overlay. The attacker must have user-level execution privileges on the device, meaning the attack is local and cannot be initiated remotely without prior access. The vulnerability impacts confidentiality, integrity, and availability, as the malicious account could potentially intercept communications, manipulate phone settings, or disrupt normal device operations. The CVSS 3.1 base score is 7.3, reflecting a high severity with the vector AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H, indicating local attack vector, low complexity, requires privileges and user interaction, unchanged scope, and high impact on confidentiality, integrity, and availability. There are no known exploits in the wild as of the published date, and no official patches are linked in the provided data, suggesting that mitigation relies on user awareness and potential OS updates from vendors. The vulnerability is classified under CWE-1021, which relates to improper restriction of operations within the bounds of a user's privilege level, confirming that the core issue is privilege escalation via UI deception techniques.
Potential Impact
For European organizations, the impact of CVE-2022-20501 can be significant, especially for enterprises relying on Android devices for communication, authentication, or mobile workforce operations. The elevation of privilege could allow attackers with local access to compromise device security, intercept sensitive communications, or install persistent malicious accounts that undermine device integrity. This could lead to data breaches, unauthorized access to corporate resources, or disruption of mobile services. Given the requirement for user interaction, social engineering campaigns targeting employees could increase the risk. Organizations in sectors such as finance, government, healthcare, and critical infrastructure, where mobile device security is paramount, may face increased risks of espionage, data leakage, or operational disruption. Additionally, the vulnerability could be leveraged in targeted attacks against high-value individuals or executives using Android devices, potentially compromising confidential communications or credentials. The lack of known exploits in the wild reduces immediate risk but does not eliminate the threat, as attackers could develop exploits leveraging this vulnerability. The broad range of affected Android versions means that many devices in use across Europe remain vulnerable, especially those not regularly updated or managed by enterprise mobility solutions.
Mitigation Recommendations
1. Deploy the latest Android security updates as soon as they become available from device manufacturers or carriers, as these will likely include patches for this vulnerability. 2. Implement enterprise mobile device management (MDM) solutions that can enforce security policies, restrict installation of untrusted apps, and monitor for suspicious account additions or privilege escalations. 3. Educate users about the risks of tapjacking and social engineering, emphasizing caution when interacting with unexpected prompts or permission requests, especially those related to account enabling or phone settings. 4. Restrict installation of apps from unknown sources and use app whitelisting to minimize the risk of malicious overlays being installed. 5. Utilize Android’s built-in security features such as screen overlay detection and disable or limit the use of apps that can draw overlays unless explicitly trusted. 6. Monitor device logs and behavior for signs of unauthorized account creation or privilege escalation attempts. 7. For high-risk environments, consider deploying endpoint detection and response (EDR) tools capable of identifying suspicious local privilege escalation activities on mobile devices. 8. Encourage users to report any unusual device behavior promptly to IT security teams for investigation.
