CVE-2026-44632 Details
Description
Yamcs is a mission control framework. Prior to 5.12.7, a server-side code injection vulnerability existed in the Yamcs algorithm evaluation engine org.yamcs.algorithms.JavaExprAlgorithmExecutionFactory, which dynamically compiled and evaluated user-controlled algorithm text through the Janino compiler without enforcing a secure sandbox, so an authenticated user with the ChangeMissionDatabase privilege could override an existing algorithm's text via the mission database REST API and inject Java code (for example using java.lang.Runtime) to achieve remote code execution on the underlying host operating system. This issue is fixed in versions 5.12.7 and 5.13.0, which disable algorithm editing by default.
A server-side code injection vulnerability has been identified in the Yamcs mission control framework, specifically within the algorithm evaluation engine component 'JavaExprAlgorithmExecutionFactory'. This vulnerability allows authenticated users with the 'ChangeMissionDatabase' privilege to inject malicious Java code into existing algorithms via the mission database REST API. The injected code is executed on the host operating system, leading to remote code execution. The issue arises because the application dynamically compiles and evaluates user-controlled algorithm text using the Janino compiler, without enforcing a secure sandbox. This vulnerability affects Yamcs versions prior to 5.12.7 and 5.13.0, and has been patched in these versions by disabling algorithm editing by default.
Users can update to Yamcs versions 5.12.7 or 5.13.0, which address the vulnerability by disabling algorithm editing by default.
