CVE-2026-20975 is a vulnerability identified in Samsung Cloud, specifically affecting versions prior to 5.6.11. This vulnerability allows local attackers to gain unauthorized access to specific files in arbitrary paths due to improper handling of insufficient permissions. With a CVSS score of 2.1, it falls under the low severity category, but it presents real risks that organizations need to understand and manage.
The potential impact of this vulnerability includes unauthorized access to sensitive files, which could lead to further security breaches or data exposure. Security practitioners should be aware that even low-severity vulnerabilities can be exploited under specific conditions, hence the need for vigilance.
Currently, there are no known exploits or public proofs of concept for this vulnerability, but the lack of active exploitation does not diminish its relevance. Organizations utilizing affected versions of Samsung Cloud should prioritize remediation as part of their security maintenance policies.
Urgency for defenders is moderate, suggesting that organizations should schedule remediation to address this vulnerability within their regular patch cycles.
Vulnerability Details
The official CVE description states: 'Improper handling of insufficient permission in Samsung Cloud prior to version 5.6.11 allows local attackers to access specific files in arbitrary path.' This vulnerability is classified under CWE-Other, indicating an improper access control mechanism.
The CVSS 4.0 score of 2.1 reflects low severity, with an attack vector classified as LOCAL and low attack complexity. No privileges are required for exploitation, and no user interaction is necessary, making this vulnerability particularly concerning in environments where users have local access.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of permission checks, allowing local users to bypass intended restrictions. As the attack vector is local, it requires the attacker to have physical or logical local access to the device. The attack complexity is low, and the attacker does not need elevated privileges, making exploitation feasible in many scenarios.
Since no user interaction is required, an attacker can exploit this vulnerability silently. The impact on confidentiality is assessed as low, while integrity and availability are not affected.
Risk & Impact Analysis
Risk to organizations includes unauthorized access to sensitive files, which could lead to data breaches or further exploitation. Although the CVSS score indicates low severity, the potential for misuse in certain environments makes this a relevant concern.
The blast radius for this vulnerability is limited to local users, but organizations must consider the implications of unauthorized access to sensitive data. Given the low exploitability score and absence of known active exploitation, organizations should still prioritize addressing this vulnerability as part of their overall security posture.
Organizations should schedule remediation actions to mitigate potential risks associated with this vulnerability. Whether through patching or implementing additional security controls, addressing this issue is essential for maintaining robust security.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
All versions of Samsung Cloud prior to 5.6.11 are affected by this vulnerability. Organizations using older versions should take immediate action to upgrade to the latest version to ensure security.
Mitigation & Remediation
To mitigate the risk associated with CVE-2026-20975, organizations should apply the necessary patches as soon as they are available. Users should upgrade to Samsung Cloud version 5.6.11 or later to ensure their systems are not vulnerable.
In addition to patching, organizations should implement configuration hardening to limit file access based on user roles and responsibilities. Monitoring for any unauthorized access attempts is also recommended to detect potential exploitation.
For further assistance, organizations may consider engaging in penetration testing to assess their security posture.
Detection Guidance
Organizations should monitor logs for indicators of unauthorized access attempts, specifically for access to sensitive files that should be restricted. Behavioral anomalies within the application usage can also indicate attempts to exploit this vulnerability.
Network signatures and alerts should be configured to detect suspicious file access patterns that deviate from normal user behavior.
