# RSQL Injection

{{#include ../banners/hacktricks-training.md}}

## Šta je RSQL?
RSQL je jezik upita dizajniran za parametarsko filtriranje unosa u RESTful API-ima. Zasnovan na FIQL (Feed Item Query Language), koji je prvobitno definisao Mark Nottingham za upitivanje Atom feed-ova, RSQL se izdvaja po svojoj jednostavnosti i sposobnosti da izrazi složene upite na kompaktan i URI-kompatibilan način preko HTTP-a. Ovo ga čini odličnim izborom kao opšti jezik upita za pretraživanje REST krajnjih tačaka.

## Pregled
RSQL Injection je ranjivost u web aplikacijama koje koriste RSQL kao jezik upita u RESTful API-ima. Slično [SQL Injection](https://owasp.org/www-community/attacks/SQL_Injection) i [LDAP Injection](https://owasp.org/www-community/attacks/LDAP_Injection), ova ranjivost se javlja kada RSQL filteri nisu pravilno sanitizovani, omogućavajući napadaču da ubaci zlonamerne upite kako bi pristupio, izmenio ili obrisao podatke bez autorizacije.

## Kako to funkcioniše?
RSQL vam omogućava da gradite napredne upite u RESTful API-ima, na primer:
```bash
/products?filter=price>100;category==electronics
```
Ovo se prevodi u strukturirani upit koji filtrira proizvode sa cenom većom od 100 i kategorijom "elektronika".

Ako aplikacija ne validira ispravno korisnički unos, napadač bi mogao da manipuliše filtrima kako bi izvršio neočekivane upite, kao što su:
```bash
/products?filter=id=in=(1,2,3);delete_all==true
```
Ili čak iskoristiti za ekstrakciju osetljivih informacija pomoću Boolean upita ili ugnježdenih podupita.

## Rizici
- **Izlaganje osetljivih podataka:** Napadač može da dohvati informacije koje ne bi trebale biti dostupne.
- **Modifikacija ili brisanje podataka:** Injekcija filtera koji menjaju zapise u bazi podataka.
- **Povećanje privilegija:** Manipulacija identifikatorima koji dodeljuju uloge putem filtera kako bi se prevarila aplikacija pristupom sa privilegijama drugih korisnika.
- **Izbegavanje kontrola pristupa:** Manipulacija filterima za pristup ograničenim podacima.
- **Impersonacija ili IDOR:** Modifikacija identifikatora između korisnika putem filtera koji omogućavaju pristup informacijama i resursima drugih korisnika bez pravilne autentifikacije.

## Podržani RSQL operatori
| Operator  | Opis | Primer  |
|:----: |:----: |:------------------:|
| `;` / `and` | Logički **AND** operator. Filtrira redove gde su *oba* uslova *tačna* | `/api/v2/myTable?q=columnA==valueA;columnB==valueB` |
| `,` / `or` | Logički **OR** operator. Filtrira redove gde je *barem jedan* uslov *tačan*| `/api/v2/myTable?q=columnA==valueA,columnB==valueB` |
| `==` | Izvodi **jednako** upit. Vraća sve redove iz *myTable* gde su vrednosti u *columnA* tačno jednake *queryValue* | `/api/v2/myTable?q=columnA==queryValue` |
| `=q=` | Izvodi **pretragu** upit. Vraća sve redove iz *myTable* gde vrednosti u *columnA* sadrže *queryValue* | `/api/v2/myTable?q=columnA=q=queryValue` |
| `=like=` | Izvodi **like** upit. Vraća sve redove iz *myTable* gde su vrednosti u *columnA* slične *queryValue* | `/api/v2/myTable?q=columnA=like=queryValue` |
| `=in=` | Izvodi **in** upit. Vraća sve redove iz *myTable* gde *columnA* sadrži *valueA* ILI *valueB* | `/api/v2/myTable?q=columnA=in=(valueA, valueB)` |
| `=out=` | Izvodi **exclude** upit. Vraća sve redove iz *myTable* gde vrednosti u *columnA* nisu *valueA* niti *valueB* | `/api/v2/myTable?q=columnA=out=(valueA,valueB)` |
| `!=` | Izvodi *nije jednako* upit. Vraća sve redove iz *myTable* gde vrednosti u *columnA* nisu jednake *queryValue* | `/api/v2/myTable?q=columnA!=queryValue` |
| `=notlike=` | Izvodi **not like** upit. Vraća sve redove iz *myTable* gde vrednosti u *columnA* nisu slične *queryValue* | `/api/v2/myTable?q=columnA=notlike=queryValue` |
| `<` & `=lt=` | Izvodi **manje od** upit. Vraća sve redove iz *myTable* gde su vrednosti u *columnA* manje od *queryValue* | `/api/v2/myTable?q=columnA<queryValue` <br> `/api/v2/myTable?q=columnA=lt=queryValue` |
| `=le=` & `<=` | Izvodi **manje od** ili **jednako** upit. Vraća sve redove iz *myTable* gde su vrednosti u *columnA* manje ili jednake *queryValue* | `/api/v2/myTable?q=columnA<=queryValue` <br> `/api/v2/myTable?q=columnA=le=queryValue` |
| `>` & `=gt=` | Izvodi **veće od** upit. Vraća sve redove iz *myTable* gde su vrednosti u *columnA* veće od *queryValue* | `/api/v2/myTable?q=columnA>queryValue` <br> `/api/v2/myTable?q=columnA=gt=queryValue` |
| `>=` & `=ge=` | Izvodi **jednako** ili **veće od** upit. Vraća sve redove iz *myTable* gde su vrednosti u *columnA* jednake ili veće od *queryValue* | `/api/v2/myTable?q=columnA>=queryValue` <br> `/api/v2/myTable?q=columnA=ge=queryValue` |
| `=rng=` | Izvodi **od do** upit. Vraća sve redove iz *myTable* gde su vrednosti u *columnA* jednake ili veće od *fromValue*, i manje ili jednake od *toValue* | `/api/v2/myTable?q=columnA=rng=(fromValue,toValue)` |

## Uobičajeni filteri
Ovi filteri pomažu u preciziranju upita u API-ima:

| Filter | Opis | Primer |
|--------|------------|---------|
| `filter[users]` | Filtrira rezultate po specifičnim korisnicima | `/api/v2/myTable?filter[users]=123` |
| `filter[status]` | Filtrira po statusu (aktivan/neaktivan, završen, itd.) | `/api/v2/orders?filter[status]=active` |
| `filter[date]` | Filtrira rezultate unutar vremenskog okvira | `/api/v2/logs?filter[date]=gte:2024-01-01` |
| `filter[category]` | Filtrira po kategoriji ili tipu resursa | `/api/v2/products?filter[category]=electronics` |
| `filter[id]` | Filtrira po jedinstvenom identifikatoru | `/api/v2/posts?filter[id]=42` |

## Uobičajeni parametri
Ovi parametri pomažu u optimizaciji API odgovora:

| Parametar | Opis | Primer |
|-----------|------------|---------|
| `include` | Uključuje povezane resurse u odgovoru | `/api/v2/orders?include=customer,items` |
| `sort` | Sortira rezultate u rastućem ili opadajućem redosledu | `/api/v2/users?sort=-created_at` |
| `page[size]` | Kontroliše broj rezultata po stranici | `/api/v2/products?page[size]=10` |
| `page[number]` | Specifikuje broj stranice | `/api/v2/products?page[number]=2` |
| `fields[resource]` | Definiše koje polja da vrati u odgovoru | `/api/v2/users?fields[users]=id,name,email` |
| `search` | Izvodi fleksibilniju pretragu | `/api/v2/posts?search=technology` |

## Izdavanje informacija i enumeracija korisnika
Sledeći zahtev prikazuje endpoint za registraciju koji zahteva email parametar da proveri da li postoji neki korisnik registrovan sa tim email-om i vraća true ili false u zavisnosti od toga da li postoji u bazi podataka:
### Zahtev

}
```
Iako se očekuje `/api/registrations?email=<emailAccount>`, moguće je koristiti RSQL filtre da se pokuša enumerisati i/ili izvući informacije o korisnicima korišćenjem specijalnih operatora:  
### Request
```

}
```
U slučaju podudaranja sa važećim email nalogom, aplikacija bi vratila informacije o korisniku umesto klasičnog *“true”*, *"1"* ili bilo čega drugog u odgovoru serveru:  
### Request
```

}]
}
}
}
```
## Izbegavanje autorizacije
U ovom scenariju, počinjemo od korisnika sa osnovnom ulogom i u kojem nemamo privilegovane dozvole (npr. administrator) da pristupimo listi svih korisnika registrovanih u bazi podataka:
### Zahtev
```
GET /api/users HTTP/1.1
Host: localhost:3000
User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:136.0) Gecko/20100101 Firefox/136.0
Accept: application/vnd.api+json
Accept-Language: es-ES,es;q=0.8,en-US;q=0.5,en;q=0.3
Accept-Encoding: gzip, deflate, br, zstd

```
### Odgovor
```

Content-Length: 0
Connection: keep-alive
Vary: Origin
Vary: Access-Control-Request-Method
Vary: Access-Control-Request-Headers
Access-Control-Allow-Origin: *
```
Ponovo koristimo filtre i specijalne operatore koji će nam omogućiti alternativni način da dobijemo informacije o korisnicima i izbegnemo kontrolu pristupa. Na primer, filtriramo *korisnike* koji sadrže slovo “*a*” u svom korisničkom *ID*-u:  
### Request
```

}, {
................
```
## Eskalacija privilegija
Veoma je verovatno da ćemo pronaći određene krajnje tačke koje proveravaju privilegije korisnika kroz njihovu ulogu. Na primer, imamo korisnika koji nema privilegije:
### Zahtev
```
GET /api/companyUsers?include=role HTTP/1.1

Korišćenjem određenih operatora mogli bismo enumerisati administratorske korisnike:  
### Request
```

}
}]
}
```
Nakon što se sazna identifikator administratorskog korisnika, bilo bi moguće iskoristiti eskalaciju privilegija zamenom ili dodavanjem odgovarajućeg filtera sa identifikatorom administratora i dobijanjem istih privilegija:

## Impersonate or Insecure Direct Object References (IDOR)
Pored korišćenja `filter` parametra, moguće je koristiti i druge parametre kao što je `include` koji omogućava uključivanje određenih parametara u rezultat (npr. jezik, država, lozinka...).

U sledećem primeru, prikazane su informacije o našem korisničkom profilu:
### Request

Kombinacija filtera može se koristiti za izbegavanje kontrole autorizacije i sticanje pristupa profilima drugih korisnika:
