Regular expression Denial of Service in MooTools

Apache Dubbo is a java based, open source RPC framework. Versions prior to 2.6.10 and 2.7.10 are vulnerable to pre-auth remote code execution via arbitrary bean manipulation in the Telnet handler. The Dubbo main service port can be used to access a Telnet Handler which offers some basic methods to collect information about the providers and methods exposed by the service and it can even allow to shutdown the service. This endpoint is unprotected. Additionally, a provider method can be invoked using the `invoke` handler. This handler uses a safe version of FastJson to process the call arguments. However, the resulting list is later processed with `PojoUtils.realize` which can be used to instantiate arbitrary classes and invoke its setters. Even though FastJson is properly protected with a default blocklist, `PojoUtils.realize` is not, and an attacker can leverage that to achieve remote code execution. Versions 2.6.10 and 2.7.10 contain fixes for this issue.

Apache Dubbo 代码问题漏洞

Apache Dubbo是美国阿帕奇（Apache）基金会的一款基于Java的轻量级RPC（远程过程调用）框架。该产品提供了基于接口的远程呼叫、容错和负载平衡以及自动服务注册和发现等功能。 Apache Dubbo 2.6.10之前版本、2.7.10 之前版本存在代码问题漏洞，该漏洞源于容易受到通过 Telnet 处理程序中的任意 bean 操作进行预授权远程代码执行的攻击，攻击者利用该漏洞可以实现远程代码执行。
