description根据 Microsoft [安全通告](https://portal.msrc.microsoft.com/en-us/security-guidance/advisory/CVE-2017-11779)，多个版本 Windows 中的 DNSAPI.dll 在处理 DNS response 时可导致 SYSTEM 权限 RCE。 以 DNS Client API DLL 10.0.15063.0 与 10.0.15063.674 为例，补丁对比， ![](https://images.seebug.org/1508147084495) 可知漏洞存在于 DNSAPI.dll 中的 Nsec3_RecordRead 函数，那么可以确定问题就是出在解析 DNS response 的 NSEC3 Resource record，为了构造 PoC，先得了解这个 "NSEC3" 的背景。首先，DNS 协议数据结构如下图所示， ![](https://images.seebug.org/1508147095992) 例如，当访问 http://justanotherbuganalysis.github.io/ 时，DNS query 如下， ``` 9d 4b 01 00 00 01 00 00 00 00 00 00 16 6a 75 73 .K...........jus 74 61 6e 6f 74 68 65 72 62 75 67 61 6e 61 6c 79 tanotherbuganaly 73 69 73 06 67 69 74 68 75 62 02 69 6f 00 00 01 sis.github.io... 00 01 .. ``` DNS response 如下， ``` 9d 4b 81 80 00 01 00 02 00 00 00 00 16 6a 75 73 .K...........jus 74 61 6e 6f 74 68 65 72 62 75 67 61 6e 61 6c 79 tanotherbuganaly 73 69 73 06 67 69 74 68 75 62 02 69 6f 00 00 01 sis.github.io... 00 01 c0 0c 00 05 00 01 00 00 0e 10 00 1b 03 73 ...............s 6e 69 06 67 69 74 68 75 62 03 6d 61 70 06 66 61 ni.github.map.fa 73 74 6c 79 03 6e 65 74 00 c0 3e 00 01 00 01 00 stly.net..>..... 00 07 08 00 04 97 65 4d 93 ......eM. ``` 可见该 DNS response 中的 Answer RRs 包含了 CNAME(0x05) 与 A(0x01) 两个 Resource record(RR)，由于该域名所在的 Domain Zone 并未配置 DNSSEC，所以在 response 中并没有 Authority RRs 与 Additional RRs。后面为了把程序执行流引到 Nsec3_RecordRead 函数，触发漏洞，在 Authority RRs 中加入特定 NSEC3 记录即可。 再来看漏洞， ``` .text:0000000180066693 movzx ecx, ax .text:0000000180066696 xor edx, edx .text:0000000180066698 call Dns_AllocateRecordEx .text:000000018006669D mov r13, rax .text:00000001800666A0 test rax, rax .text:00000001800666A3 jz short loc_18006668C .text:00000001800666A5 mov al, [r14] .text:00000001800666A8 mov [r13+20h], al .text:00000001800666AC mov al, [r14+1] .text:00000001800666B0 mov [r13+21h], al .text:00000001800666B4 movzx ecx, word ptr [r14+2] ;
