What is Codemeter Runtime Server?

The Codemeter Runtime Server is a software application used for managing licenses and controlling access to digital content. However, recent security research has identified a critical vulnerability in the server that could allow an attacker to crash the system or overwrite essential files.

Vulnerability Overview

The vulnerability, known as CVE-2021-41057, affects all versions of Codemeter Runtime prior to version 7.30aģ.2. It is classified as an improper privilege management issue (CWE-269) and has been assigned a CVSS v3 base score of 7.1.

Exploitation

An attacker with local access to the Microsoft Windows operating system could exploit this vulnerability by setting up a link to a special system file used with CmDongles. This would allow them to improperly control file access permissions, leading to a denial-of-service condition or the overwrite of essential files.

Mitigation Strategies

To reduce the risk of exploitation until a fixed version of the Codemeter Runtime Server can be installed, Wibu-Systems recommends the following measures:

* Disable the 'Mass Storage' container type in CodeMeter.

* Restrict unprivileged access to machines running the CodeMeter License Server service.

* Update to the latest version of the Codemeter Runtime.

The vulnerability in the Codemeter Runtime Server highlights the importance of regular software updates and proper configuration to prevent security exploits. Users of the system should take immediate action to mitigate the risk of exploitation until a fixed version can be installed.
