GHSA-3jxh-6635-6jwp
Path traversal in Concrete CMS
Quick fix
GHSA-3jxh-6635-6jwp — concrete5/core: upgrade to the fixed version with the command below.
composer require concrete5/core:^9.1.0Details
Concrete 8.5.7 and below as well as Concrete 9.0 through 9.0.2 allow traversal in /index.php/ccm/system/file/upload which could result in an Arbitrary File Delete exploit. This was remediated by sanitizing /index.php/ccm/system/file/upload to ensure Concrete doesn’t allow traversal and by changing isFullChunkFilePresent to have an early false return when input doesn't match expectations.Concrete CMS Security team ranked this 5.8 with CVSS v3.1 vector AV:N/AC:H/PR:H/UI:N/S:C/C:N/I:N/A:H.
