Security readout for executives and security teams
This CVE is a privacy and data leakage issue in older Samsung KNOX versions. A malicious local app could read data copied inside KNOX because the clipboard manager did not properly verify the caller. Business impact depends on whether affected KNOX-era devices handled passwords, tokens, or sensitive corporate content through clipboard use. Exposure is limited to devices running Samsung KNOX 1.0.0 or 2.3.0, especially where users can install untrusted or unmanaged apps. The bundle’s structured affected-product data is incomplete, so confirm versions through device inventory or vendor records. Treat this as a targeted legacy mobile data exposure risk, not an internet-scale emergency. Prioritize asset confirmation and retirement or update decisions for any remaining affected KNOX devices used with sensitive corporate data. Mitigation focus: Identify Samsung devices still running KNOX 1.0.0 or 2.3.0.; Check Samsung or carrier guidance for supported firmware or KNOX updates.; Restrict installation of untrusted, sideloaded, or unmanaged apps on affected devices..
