CVE-2026-46562— Yamcs 代码注入漏洞

Yamcs: Remote Code Execution via Mission Database algorithm override

Yamcs is a mission control framework. Prior to 5.12.7, the Nashorn ScriptEngine used to evaluate user-supplied JavaScript algorithm text in yamcs-core/src/main/java/org/yamcs/algorithms/ScriptAlgorithmExecutorFactory.java was constructed without a ClassFilter, so a user with the ChangeMissionDatabase privilege could override an algorithm through the MdbOverrideApi.updateAlgorithm endpoint and supply JavaScript that reaches arbitrary Java classes (for example Java.type("java.lang.Runtime").getRuntime().exec(...)) to execute arbitrary OS commands as the Yamcs process; in the default configuration with no security.yaml the built-in guest user has superuser=true, making the issue reachable without authentication. This issue is fixed in versions 5.12.7 and 5.13.0, which disable algorithm editing by default.

Yamcs 代码注入漏洞

Yamcs yamcs是Yamcs团队的航天器遥测数据处理与监控系统。 Yamcs 5.12.7之前版本存在代码注入漏洞，该漏洞源于Nashorn ScriptEngine在评估用户提供的JavaScript算法文本时未使用ClassFilter，导致具有ChangeMissionDatabase权限的用户可通过MdbOverrideApi.updateAlgorithm端点覆盖算法，并提交可访问任意Java类的JavaScript(如Java.type("java.lang.Runtime").getR
