Overview
The CVE-2025-32320 is a critical cybersecurity vulnerability found in System UI that allows potential unauthorized access to other users’ images. This vulnerability could be exploited to escalate local privileges without requiring any additional execution privileges or user interaction. The implications of such a breach could be significant, leading to potential system compromise or data leakage.

How the Exploit Works
The exploit takes advantage of a confused deputy issue in the System UI. This vulnerability allows a malicious actor to view other users’ images without the need for additional execution privileges. The flaw lies in the failure of the System UI to properly isolate user data, thus allowing an attacker within the local system to escalate privileges and access data outside of their permission scope.
Conceptual Example Code
While the specific details of code that would exploit this vulnerability are not provided, a conceptual approach would involve a script or program that accesses the System UI’s image data storage. The below pseudocode provides a high-level concept of such an exploit:
def exploit_system_ui_vulnerability():
# Assume the attacker has already gained local access
user_images = system_ui.get_all_user_images()
for image in user_images:
if not image.has_permission(current_user):
print("Accessing image without permission: ", image.id)
malicious_access(image)
exploit_system_ui_vulnerability()Please note that this is a conceptual representation only and may not represent an actual exploit.
Mitigation Guidance
To mitigate this vulnerability, it is recommended to apply the vendor-provided patch immediately. Until the patch can be applied, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. These systems should be configured to monitor and alert on abnormal access patterns or unusual data requests within the System UI.
