Quick assessment

Affected
wibu-systems-ag codemeter-runtime
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

WIBU-SYSTEMS CodeMeter Runtime是德国WIBU-SYSTEMS公司的一款软件加密与授权管理运行时组件。 WIBU-SYSTEMS CodeMeter Runtime 8.41a之前版本和9.10之前版本存在权限许可和访问控制问题漏洞，该漏洞源于配置命令处理程序未实施网络来源限制，导致仅限本地或同网络客户端执行的命令可被任意远程对等方执行，攻击者可能读取敏感配置数据并覆盖Server.ini中的选定值，包括CodeMeter WebAdmin凭据的哈希，从而实现WebAdmin接

Vulnerability Title
Improper Access Control in Local-Only Configuration Commands
Source: CVE Program / CVE List V5
Vulnerability Description
If CodeMeter Runtime before 8.41a or 9.10 is configured as a server, the configuration command handler does not enforce network- origin restrictions. Commands intended only for local or same-network clients can therefore be executed by arbitrary remote peers. An attacker can read potentially sensitive configuration data and overwrite selected values in Server.ini. This does include the hash of the credentials for the CodeMeter WebAdmin, enabling WebAdmin takeover.
