About oa-system-attack
A security-testing skill for domestic Chinese OA and intranet systems, including Seeyon, Weaver, Yonyou, Tongda, and Landray. It provides identification clues, common vulnerability references, and a general validation workflow.
Key features
- 01Identify common OA systems
- 02Look up vulnerability paths and types
- 03Check default passwords and known flaws
- 04Scan with nuclei OA-related tags
- 05Prioritize vulnerability validation
Use cases
- 01Inventory OA systems on an intranet
- 02Screen for common OA vulnerabilities
- 03Plan steps for authorized security testing

From the project README国产 OA/内网系统漏洞利用
国内比赛内网环境几乎必有 OA 系统——它们历史漏洞多、补丁率低、权限通常较高。

Phase 1: OA 系统识别
# Web 指纹识别
whatweb http://TARGET
curl -sI http://TARGET | grep -i "Server"
curl -s http://TARGET | grep -iE "seeyon|致远|weaver|ecology|泛微|yonyou|用友|tongda|通达|landray|蓝凌|ezoffice|万户"
# 常见路径指纹
curl -s http://TARGET/seeyon/ # 致远 OA
curl -s http://TARGET/weaver/ # 泛微 E-cology
curl -s http://TARGET/mobile/ # 泛微 E-mobile
curl -s http://TARGET/ispirit/ # 通达 OA
curl -s http://TARGET/sys/ # 蓝凌 OA
curl -s http://TARGET/portal/ # 用友 NC
Phase 2: 系统 → 漏洞速查
致远 OA (Seeyon) — 漏洞最多
| 漏洞 | 路径 | 类型 |
|---|---|---|
| Session 泄露 | /seeyon/thirdpartyController.do | 任意用户登录 |
| 文件上传 | /seeyon/htmlofficeservlet | RCE |
| 反序列化 | /seeyon/autoinstall.do.css | RCE |
| SSRF | /seeyon/ajax.do | SSRF |
| SQL 注入 | /seeyon/webmail.do | SQLi |
泛微 OA (Weaver/E-cology) — 出现频率最高
| 漏洞 | 路径 | 类型 |
|---|---|---|
| SQL 注入 | /mobile/browser/WorkflowCenterTreeData.jsp | SQLi |
| 文件上传 | /weaver/bsh.servlet.BshServlet | RCE |
| SSRF | /ssrf/proxy | SSRF |
| 数据库配置读取 | /mobile/DBconfigReader.jsp | 信息泄露 |
| 命令执行 | /api/integration/workflowToDoc | RCE |
用友 NC (Yonyou) — 权限通常高
| 漏洞 | 路径 | 类型 |
|---|---|---|
| 反序列化 | /servlet/~ic/bsh.servlet.BshServlet | RCE |
| 文件上传 | /servlet/FileReceiveServlet | 任意文件上传 |
| 目录遍历 | /NCFindWeb | 信息泄露 |
| SSRF | /servlet/~uap/nc.itf.iufo.FunctionServlet | SSRF |
通达 OA — 入门级目标
| 漏洞 | 路径 | 类型 |
|---|---|---|
| 文件上传+包含 | /ispirit/im/upload.php + /ispirit/interface/gateway.php | RCE |
| 任意用户登录 | /logincheck_code.php | 认证绕过 |
| SQL 注入 | /general/approve_center/archive/getTableInfo.php | SQLi |
蓝凌 OA (Landray) — SSRF 到 RCE
| 漏洞 | 路径 | 类型 |
|---|---|---|
| SSRF → RCE | /sys/ui/extend/varkind/custom.jsp | RCE |
| 任意文件读取 | /sys/ui/extend/varkind/custom.jsp | 文件读取 |
| 反序列化 | /sys/search/sys_search_main/sysSearchMain.do | RCE |

Phase 3: 通用攻击策略
发现 OA 系统后:
1. 确认系统类型和版本
2. 尝试默认口令
3. 查已知 CVE / Nday
4. nuclei 扫描: nuclei -u TARGET -tags oa,seeyon,weaver,tongda
5. 手动验证高危漏洞（RCE > 文件上传 > SQLi > 信息泄露）
6. 获取 shell 后收集内网凭据
