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.

themoos core-moos是themoos组织的一个提供网络功能的操作系统。 themoos core-moos 10.4.0及之前版本存在缓冲区错误漏洞，该漏洞源于CMOOSCommPkt在反序列化过程中对四字节数据包处理不当，导致缓冲区过度读取，攻击者可通过TCP连接MOOSDB端口发送特制短包，在身份验证前读取内存。
