Hunt LDAP Injection and XPath Injection — authentication bypass, blind char-by-char attribute exfiltration, AD user/group enumeration, XML-store XPath bypass. Covers the LDAP special-character set (* ( ) \\ NUL /), search-filter-context vs DN-injection, parenthesis-balancing, AND/OR filter logic, and {SSHA}/{CRYPT} userPassword exfil on non-AD directories. Use when target uses LDAP/AD authentication, corporate SSO with a directory backend, an address-book/people-search API, or XML-based data…
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-LDAP — LDAP Injection & XPath Injection
> Grounding note: LDAP injection is rarely disclosed with verbatim payloads on
> public platforms (most live on internal-pentest reports). This skill is
> grounded in the **OWASP LDAP Injection Prevention / Testing Guide
> (WSTG-INPV-06)**, **PortSwigger Web Security Academy (LDAP injection)**, and
> the **RFC 4515** filter grammar — all publicly verifiable references rather
> than invented HackerOne IDs. Do not cite a report you cannot link.
## Crown Jewel Targets
LDAP injection that bypasses authentication = **Critical**. Blind attribute
exfiltration of credentials/secrets = **High**. AD enumeration alone = Medium-High.
**Highest-value chains:**
- **LDAP auth bypass** — close the `uid` filter and append an always-true OR so the
bind/search returns the admin entry without a valid password.
- **Blind attribute exfil** — char-by-char extraction of an attribute value via a
boolean oracle (login success/failure, result count, or response length).
- **userPassword hash exfil (non-AD only)** — on OpenLDAP/389-DS the
`userPassword` attribute can hold `{SSHA}`/`{CRYPT}` hashes that ARE readable

How to install
mdr add novaestellar/novahaku/hunt-ldap@sha256:167f4d57b22f3c68The 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.
