CVE-2022-39367 Detail


QTIWorks is a software suite for standards-based assessment delivery. Prior to version 1.0-beta15, the QTIWorks Engine allows users to upload QTI content packages as ZIP files. The ZIP handling code does not sufficiently check the paths of files contained within ZIP files, so can insert files into other locations in the filesystem if they are writable by the process running the QTIWorks Engine. In extreme cases, this could allow anonymous users to change files in arbitrary locations in the filesystem. In normal QTIWorks Engine deployments, the impact is somewhat reduced because the default QTIWorks configuration does not enable the public demo functionality, so ZIP files can only be uploaded by users with "instructor" privileges. This vulnerability is fixed in version 1.0-beta15. There are no database configuration changes required when upgrading to this version. No known workarounds for this issue exist.


CVSS 3.x Severity and Metrics:

Base Score:  6.5 MEDIUM
Vector:  CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N

Nist CVSS score does not match with CNA score
CNA:  GitHub, Inc.
Base Score:  8.6 HIGH
Vector:  CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:H/A:N

NVD Analysts use publicly available information to associate vector strings and CVSS scores. We also display any CVSS information provided within the CVE List from the CNA.

Note: It is possible that the NVD CVSS may not match that of the CNA. The most common reason for this is that publicly available information does not provide sufficient detail or that information simply was not available at the time the CVSS vector string was assigned.
