漏洞简介

Microsoft Jet数据库是MS Office应用程序中广泛使用的轻型数据库。

Jet数据库在处理畸形MDB文件时存在缓冲区溢出漏洞，远程攻击者可能利用此漏洞通过诱使用户处理恶意文件，控制服务器。

Office Access在解析MDB文件时会调用Jet数据库引擎(msjet40.dll)，如果解析了恶意的MDB文件就会在以下代码中触发栈溢出：

C：＼Windows＼System32＼msjet40.dll，版本为4.0.8618.0

.text：1B0B72BB mov ecx, edx ; ecx=0x5200

.text：1B0B72BD mov esi, edi ; esi point

to the datas

.text：1B0B72BF mov ebp, ecx ; which

can be find in the mdb file

.text：1B0B72C1 lea edi, [esp+40h] ; edi point

to stack memory

.text：1B0B72C5 shr ecx, 2

.text：1B0B72C8 rep movsd ; stack overflow!!

.text：1B0B72CA mov ecx, ebp

.text：1B0B72CC mov eax, [eax+1]

.text：1B0B72CF and ecx, 3

.text：1B0B72D2 rep movsb

以下为调试信息：

请注意由于这是Jet引擎中的漏洞，因此一些网络空间供应商也可能受影响。攻击者可以上传.asp和.mdb文件，并通过ADODB.Connection服务器对象利用这个漏洞。
