CVE-2022-24784

Statamic is a Laravel and Git powered CMS. Before versions 3.2.39 and 3.3.2, it is possible to confirm a single character of a user's password hash using a specially crafted regular expression filter in the users endpoint of the REST API. Multiple such requests can eventually uncover the entire hash. The hash is not present in the response, however the presence or absence of a result confirms if the character is in the right position. The API has throttling enabled by default, making this a time intensive task. Both the REST API and the users endpoint need to be enabled, as they are disabled by default. The issue has been fixed in versions 3.2.39 and above, and 3.3.2 and above.

Description

It was possible to confirm a single character of a user's password hash (just the hash, not the password) using a specially crafted regular expression filter in the users endpoint of the REST API. Many requests could eventually uncover the entire hash.

The hash would not be in the response, however the presence or absence of a result would confirm if the character was in the right position. It would take a long time since the API has throttling enabled by default.

Additionally, the REST API would need to be enabled, as well as the users endpoint. Both of which are disabled by default.

Resolution

Filtering by password or password hash has been disabled.
