2019-SV1 Reader Used Files

affects OMERO.server versions 5.0.0 to 5.6.0

back to Advisories

Synopsis

The reading of files from imported image filesets may circumvent OMERO permissions restrictions.

Background

OMERO uses Bio-Formats to read image data from the files that were uploaded at import time. There is the possibility of crafting an image import that causes Bio-Formats to read a file from the OMERO server to which the user does not have read access.

For various codepaths through the server, OMERO 5.6.1 introduces checks that the files regarded by Bio-Formats as being used by the image are judged by OMERO's permissions system to be readable by the user.

This vulnerability is identified as CVE-2019-9944.

Affected Packages

OMERO.server from 5.0.0 to 5.6.0 inclusive.

Impact

Medium severity.

CVSS score 4.4 vector AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:R

Resolution

All OMERO.servers should be upgraded to at least 5.6.1.
