Improper Control of Generation of Code ('Code Injection')

CVE-2025-67847

High
8.8/10

Summary

A flaw was found in Moodle versions through 4.1.21, 4.2.x through 4.4.11, 4.5.x through 4.5.7, 5.0.x through 5.0.3, and 5.1.x through 5.1.0. An attacker with access to the restore interface could trigger server-side execution of arbitrary code. This is due to insufficient validation of restore input, which leads to unintended interpretation by core restore routines. Successful exploitation could result in a full compromise of the Moodle application.

CWE-94 - Code Injection

Code injection is a type of vulnerability that allows an attacker to execute arbitrary code. This vulnerability fully compromises the machine and can cause a wide variety of security issues, such as unauthorized access to sensitive information, manipulation of data, denial of service attacks etc. Code injection is different from command injection in the fact that it is limited by the functionality of the injected language (e.g. PHP), as opposed to command injection, which leverages existing code to execute commands, usually within the context of a shell.
