Detailsinfo

A vulnerability, which was classified as critical, has been found in Craft CMS. This issue affects the function Craft::configure of the component getNext/getPrev. The manipulation of the argument elementIds with an unknown input leads to a sql injection vulnerability. Using CWE to declare the problem leads to CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Craft CMS 4.0.0 before 4.18.9 and 5.0.0 before 5.11.2 contains a blind SQL injection vulnerability because the sandbox-exposed getNext() and getPrev() methods pass arbitrary criteria arrays to Craft::configure() without removing SQL-bearing properties such as orderBy and where. Authenticated control panel users can supply a crafted elementIds value, rendered as a sandboxed template, to obtain a conditional SQL oracle under the Craft database account.
