CVE-2020-26606

Vulnerability

On Samsung mobile devices with Android versions O(8.x), P(9.0), Q(10.0), and R(11.0), a vulnerability in the Secure Folder implementation allows an attacker to access protected content via a debugging command [1]. The exact affected software build numbers are not detailed in the available references.

Exploitation

An attacker requires local device access or the ability to execute commands on the device (e.g., via USB debugging if enabled or through other means) to issue the specific debugging command. The attacker does not need to authenticate to the Secure Folder to trigger the access [1].

Impact

Successful exploitation results in unauthorized access to Secure Folder content, which may include private files, photos, and other sensitive data normally isolated by the Samsung Knox container. The attacker gains the ability to read this protected information, leading to a breach of confidentiality [1].

Mitigation

Samsung released a security update in October 2020 as part of its monthly maintenance release. Users should apply the latest firmware update for their device model. The Samsung ID for this issue is SVE-2020-18673. No workaround is documented in the available references [1].
