CVE-2024-20867

Vulnerability

Samsung Email versions prior to 6.1.91.14 suffer from an improper privilege management vulnerability. The bug resides in how the application handles access control for its internal data; a local attacker without special privileges can bypass intended permission checks and read sensitive information stored by the app. The affected versions are those before the 6.1.91.14 update, as disclosed in the Samsung Mobile Security advisory for May 2024 [1].

Exploitation

An attacker must have local access to the device (e.g., via a malicious app or physical access) and does not require any additional authentication or user interaction beyond normal device usage. The attacker can trigger the vulnerability by invoking a specific inter-process communication (IPC) call or accessing a component that exposes the stored data without proper privilege enforcement [1].

Impact

Successful exploitation allows the attacker to read sensitive information that the Samsung Email application has stored, potentially including email content, account credentials, or other private user data. The disclosure is read-only; no write or execute capability is gained [1].

Mitigation

The vulnerability is fixed in Samsung Email version 6.1.91.14, released in May 2024. Users should update the app through the Galaxy Store or official Samsung channels. No workaround is available for unpatched versions. The CVE is not listed on CISA's Known Exploited Vulnerabilities catalog as of the publication date [1].
