Local file read and write via insecure permissions
Published Mar 11, 2021 · Updated Sep 16, 2024
Weak file permissions in IBM Db2 9.7, 10.1, 10.5, 11.1, and 11.5 allow local users to read and write specific files. Db2 creates some files with insecure permissions, but IBM has not identified the files or published the permission-setting operation. Local system access is required, and the documented consequence is limited to reading and modifying those files.
