Quick assessment

Affected
CISA Malcolm
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.

随附的示例环境配置文件中包含一个固定的、公开已知的秘密值，该值用于为捆绑的网络包分析组件签发认证 Cookie。如果部署时将该示例文件直接复制为正式配置，而未执行会重新生成该值的初始化例程，系统就会使用这个已知的默认值。因此，知晓该默认值的攻击者能够伪造该组件的有效认证 Cookie。

Source: CVE Program / CVE List V5
Vulnerability Description
An example environment-configuration file ships with a fixed, publicly-known secret value used to sign authentication cookies for a bundled packet-analysis component. A deployment that copies this example file into active configuration without running the setup routine that regenerates the value will use the known default, allowing an attacker aware of the default to forge valid authentication cookies for that component.
