Quick assessment

Affected
themoos core-moos
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.

MOOS 核心库 core-moos 在 10.4.0 及之前版本中，在 MOOSDB 的消息处理过程中未能正确验证客户端身份，使得经过认证的攻擊者可以通过在序列化消息中提供任意的源标识符，将写操作归因于其他客户端。攻击者可以利用认证连接身份与线路中提供的源归属之间的脱节，伪造消息来源，并取消第三方的订阅。

Vulnerability Title
MOOS core-moos through 10.4.0 MOOSDB Message Source Spoofing via Wire Identity
Source: CVE Program / CVE List V5
Vulnerability Description
MOOS core-moos through 10.4.0 fails to validate client identity in MOOSDB message processing, allowing authenticated attackers to attribute writes to other clients by supplying arbitrary source identifiers in serialized messages. Attackers can forge message origins and cancel third-party subscriptions by exploiting the disconnect between authenticated connection identity and wire-supplied source attribution.
