CVE-2021-29441
Assigner: GitHub_M
Published: 2021-04-27T20:20:20
State: PUBLISHED
affected: product: nacos
vendor: alibaba
versions: status: affected
version: < 1.4.1
descriptions: value: Nacos is a platform designed for dynamic service discovery and configuration and service management. In Nacos before version 1.4.1, when configured to use authentication (-Dnacos.core.auth.enabled=true) Nacos uses the AuthFilter servlet filter to enforce authentication. This filter has a backdoor that enables Nacos servers to bypass this filter and therefore skip authentication checks. This mechanism relies on the user-agent HTTP header so it can be easily spoofed. This issue may allow any user to carry out any administrative tasks on the Nacos server.
