hunt-ldap

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 stores queried with XPath.

# 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 Do not cite a report you cannot link.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.
