SCA: security update for craftcms/cms (GHSA-5fvc-7894-ghp4)
critical Tenable Self-Hosted Container Security Plugin ID 438154
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- Craft is a content management system (CMS). Prior to 5.9.0-beta.1 and 4.17.0-beta.1, Craft CMS implements
a blocklist to prevent potentially dangerous PHP functions from being called via Twig non-Closure arrow
functions. In order to be able to successfully execute this attack, you need to either have
allowAdminChanges enabled on production, or a compromised admin account, or an account with access to the
System Messages utility. Several PHP functions are not included in the blocklist, which could allow
malicious actors with the required permissions to execute various types of payloads, including RCEs,
arbitrary file reads, SSRFs, and SSTIs. This vulnerability is fixed in 5.9.0-beta.1 and 4.17.0-beta.1.
