漏洞简介

BrightStor ARCserve Backup可为各种平台的服务器提供备份和恢复保护功能。

BrightStor ARCserve Backup的队列服务实现上存在漏洞，远程攻击者可能利用此漏洞控制服务器。

如果向BrightStor的ARCserve Backup消息队列服务LQserver.exe发送了畸形的ONRPC协议请求的话，就会在Queue.dll中触发内存破坏。仅可以通过调用0x0006097d进程ID(LQserver.exe的特定Proc ID)下的0x76(数据队列请求)操作才可以触发这个漏洞。在初始化这个过程后，LQServer.exe就会调用有漏洞的DLL文件Queue.dll，这个过程未经任何验证便处理了用户数据并引用为变量，如下所示：

＜lqserver.exe＞

100161B0 MOV EDX,DWORD PTR DS：[ECX+4] ; Move Arbitrary Pointer ＃2 into EDX

100161B3 PUSH EDX ; Push Arbitrary Pointer ＃2 onto the Stack

100161B4 MOV EAX,DWORD PTR SS：[EBP+8] ; Move (0x0113F8A8 the address to Arbitrary

; Pointer ＃1) into EAX

100161B7 MOV ECX,DWORD PTR DS：[EAX] ; Move Arbitrary Pointer ＃1 into ECX

100161B9 PUSH ECX ; Push Arbitrary Pointer ＃1 onto the Stack

100161BA CALL QUEUE.10012816 ; CALL Vulnerable DLL

...

＜queue.dll＞

1001281C CMP DWORD PTR SS：[EBP+8],0 ; EBP + 8 points to Arbitrary Pointer ＃1 - This makes

; sure our pointer isn t NULL.

10012820 JNZ SHORT QUEUE.10012829 ; Since our pointer isn t NULL we jump

10012829 MOV EAX,DWORD PTR SS：[EBP+8] ; Load Arbitrary Pointer ＃1 into EAX

1001282C MOV DWORD PTR SS：[EBP-4],EAX ; Write Arbitrary Pointer into EBP-4 (0x00D39618)

1001282F CMP DWORD PTR DS：[10037884],0 ; This checks for an error message field - NULL

; signifies The operation completed successfully

10012836 JE SHORT QUEUE.10012870 ; Jump is taken

10012870 MOV EAX,DWORD PTR SS：[EBP+C] ; Move Arbitrary Pointer ＃2 into EAX

10012873 PUSH EAX ; Push Arbitrary Pointer ＃2 onto the stack

10012874 PUSH QUEUE.10037884 ; Push NULL

10012879 MOV ECX,DWORD PTR SS：[EBP-4] ; Move Arbitrary Pointer ＃1 into ECX

1001287C MOV EDX,DWORD PTR DS：[ECX] ; Move Arbitrary Pointer ＃1 into EDX

1001287E MOV ECX,DWORD PTR SS：[EBP-4] ; Move Arbitrary Pointer ＃1 into ECX

10012881 CALL DWORD PTR DS：[EDX] ; Call Arbitrary Pointer ＃1

这时Queue.dll引用并调用了Arbitrary Pointer ＃1，然后会调用Arbitrary Pointer ＃2。在调用Arbitrary Pointer ＃2后，攻击者就可以完全控制代码的执行并重新定向Queue.dll执行任意代码。攻击完成后，LQserver.exe会崩溃，必须通过CA Domain Server服务手工重启。
