CVE-2025-20960 is a medium-severity vulnerability classified under CWE-285 (Improper Authorization) affecting Samsung Mobile Devices. The flaw exists in the CocktailBarService component prior to the Samsung Mobile SMR (Security Maintenance Release) May-2025 Release 1. Specifically, the vulnerability arises from improper handling of insufficient permission checks, allowing local attackers to invoke privileged APIs without proper authorization. The vulnerability requires local access (AV:L), has low attack complexity (AC:L), does not require privileges (PR:N) or user interaction (UI:N), and impacts integrity (I:L) but not confidentiality or availability. Exploitation could allow a local attacker to perform unauthorized actions that modify or manipulate device state or data integrity, potentially leading to unauthorized changes in device behavior or security settings. However, the vulnerability does not allow remote exploitation and does not directly compromise confidentiality or availability. No known exploits are currently reported in the wild, and no official patches have been linked yet, though it is expected that Samsung will address this in their May-2025 security update. The vulnerability is limited to Samsung Mobile Devices running affected versions prior to the May-2025 SMR patch, and requires local access to the device, which may limit the attack surface to scenarios where an attacker has physical or local software access.

For European organizations, the impact of CVE-2025-20960 depends largely on the prevalence of Samsung Mobile Devices within their operational environment and the sensitivity of data or operations conducted on those devices. Since the vulnerability allows local attackers to access privileged APIs without proper authorization, it could be exploited by malicious insiders or through malware that gains local execution on the device. This could lead to unauthorized modifications of device settings or security controls, potentially undermining device integrity and trustworthiness. In sectors such as finance, healthcare, or government where mobile devices are used for sensitive communications or access to critical systems, this vulnerability could facilitate lateral movement or privilege escalation on compromised devices. However, the requirement for local access and lack of remote exploitability reduce the risk of widespread remote attacks. Organizations with Bring Your Own Device (BYOD) policies or those that use Samsung devices extensively should be particularly vigilant. The absence of known exploits in the wild currently lowers immediate risk, but the vulnerability should be addressed proactively to prevent future exploitation.

To mitigate CVE-2025-20960 effectively, European organizations should: 1) Ensure all Samsung Mobile Devices are updated promptly with the May-2025 SMR patch or later once available, as this will contain the fix for the improper authorization issue. 2) Enforce strict device access controls to prevent unauthorized local access, including strong lock screen policies, biometric authentication, and session timeouts. 3) Deploy mobile device management (MDM) solutions to monitor device integrity, enforce security policies, and restrict installation of untrusted applications that could exploit local vulnerabilities. 4) Educate users about the risks of installing untrusted software or granting local access to unknown parties. 5) Conduct regular security audits and penetration testing focusing on mobile device security to detect potential misuse of privileged APIs or unauthorized access attempts. 6) Limit the use of privileged APIs to only trusted applications and monitor API usage logs for anomalies. 7) For high-security environments, consider isolating sensitive mobile device usage or employing hardened devices with additional security controls.
