hunt-ldap

hunt-ldap is a skill for Claude Code, Codex from uphiago/recon-skills. It costs 118 tokens per session (4,501 once invoked), scanned A, original, MIT.

A security-testing guide for LDAP and XPath injection. LDAP is commonly used to look up users and groups, while XPath queries data inside XML documents.

In plain words
What is it for?
Use it to test authentication forms, directory searches, XML-backed features, and blind extraction of LDAP attributes.
Why use it?
It helps detect inputs that can alter directory or XML queries, potentially bypassing login checks or revealing user, group, or credential data.

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

hunt-ldap scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

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 Do not cite a report you cannot link.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 by query. See the AD-vs-generic warning below.
  • XPath injection auth bypass' or '1'='1 against XML-backed auth.

CRITICAL — Active Directory vs generic LDAP

Do not conflate the two. They behave very differently:

Generic LDAP (OpenLDAP, 389-DS, ApacheDS) Active Directory
Password attribute userPassword — may hold {SSHA}/{MD5}/{CRYPT} and is readable if ACL allows unicodePwdwrite-only, never returned by any search
Hash exfil via injection Possible where ACLs leak userPassword Not possible — there is no readable hash attribute over LDAP
Useful enum attrs uid, cn, mail, userPassword sAMAccountName, userPrincipalName, mail, memberOf, description (often holds plaintext secrets!)

Do not tell a reader that blind LDAP injection yields AD password hashes — it does not. unicodePwd is write-only. Against AD, the win is enumeration (sAMAccountName, memberOf, description/info fields that admins misuse to store passwords) and auth bypass — not hash dumping. The hash-exfil technique applies only to non-AD directories exposing userPassword.

hunt-ldap is a skill published in the GitHub repository uphiago/recon-skills (1,251 stars, last pushed 8d ago), licensed MIT. It adds 118 tokens to every session and 4,501 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
