Local arbitrary file write via changedSource authorization bypass
Published Jun 5, 2023 · Updated Nov 22, 2024
Improper access control in KylinSoft kylin-software-properties before 0.0.1-130 allows local users to write arbitrary files. The public record identifies changedSource as the affected function but does not disclose which authorization check is absent or how its input selects a file. A low-privileged local account is required, and successful exploitation can alter files accessible to the privileged component.
