|漏洞详情
NovelleDirectory是一个的跨平台的目录服务器。NovelleDirectory默认绑定在TCP524上的dhost.exe服务没有正确地解析通过NetwareCore协议传送的opcode0x24、0x0F,远程攻击者可以向该服务提交恶意请求触发堆溢出;运行在TCP8028和8030端口上的Web控制台在处理SOAP请求中的Content-Length头时未经正确的边界检查便执行了拷贝操作,这可能触发整数溢出或堆溢出。成功利用上述任意漏洞都可能导致执行任意指令。

-- Vulnerability Details:

This vulnerability allows attackers to execute arbitrary code on

vulnerable installations of Novell eDirectory. Authentication is not

required to exploit this vulnerability.

The specific flaw resides in the web console running on TCP ports 8028

and 8030. The server exposes a web interface and accepts SOAP

connections. While parsing the Content-Length header within a SOAP

request an integer overflow can occur. This integer overflow triggers a

subsequent overflow during a memory copy operation leading to arbitrary

code execution under the context of the SYSTEM user.

-- Vendor Response:

Novell has issued an update to correct this vulnerability. More
