Hunt NoSQL Injection — MongoDB operator injection ($where, $regex, $gt, $ne), CouchDB, Redis command injection, auth bypass via NoSQLi, data dump. Use when target uses MongoDB/Mongoose, CouchDB, Redis, or shows NoSQL error messages.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# HUNT-NOSQLI — NoSQL Injection
## Crown Jewel Targets
NoSQL injection is most valuable when it bypasses authentication (Critical) or leaks the entire user collection (High).
**Highest-value chains:**
- **MongoDB auth bypass** — `{"username": {"$gt": ""}, "password": {"$gt": ""}}` logs in as first user in collection (usually admin)
- **$where JS injection** — if $where is enabled: blind injection → data exfil
- **Redis command injection** — via SSRF or direct TCP, SLAVEOF attacker-ip → config write → webshell
- **Elasticsearch injection** — _search endpoint with Groovy script injection (pre-5.0) → RCE
---
## Attack Surface Signals
### URL & Param Patterns
```
/api/users/login POST with JSON body
/api/search?q=
/api/find?filter=
/api/query?where=
Any endpoint accepting JSON body with username/password
```
### Stack Signals
| Signal | Vector |
|--------|--------|
| MongoDB error messages in response | Operator injection |
| mongoose / monk in JS bundles | ODM patterns |
| X-Powered-By: Express | Node.js + MongoDB common stack |
| CouchDB/_utils UI exposed | Futon/Fauxton admin |
| Redis port 6379 open (via SSRF) | CONFIG SET / SLAVEOF |

How to install
mdr add novaestellar/novahaku/hunt-nosqli@sha256:6e0357a5372956aeThe line at the top of this page pins the label git:20260910.546fe86, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
