Hunt LDAP injection and bind-trust flaws where untrusted input reaches a directory query or an authentication bind: a request value spliced into a search filter or a distinguished name without escaping, letting the caller alter the filter logic or the search base, and authentication flows that bind with attacker-influenced credentials in ways that permit anonymous or unauthenticated bind to pass as success. Covers filter metacharacter injection, DN injection that changes the subtree searched…
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
# Hunting LDAP injection and bind trust: when a filter or a bind decides who you are LDAP sits under a great deal of enterprise authentication and lookup, and it has two distinct injection-shaped failures. The first is classic filter and distinguished-name injection: when a request value is spliced into a search filter or a DN without escaping the directory's metacharacters, the attacker rewrites the filter's logic (turning a scoped match into a match-anything clause) or redirects the search to a different subtree. The second is a bind-trust failure: LDAP permits anonymous and unauthenticated binds, and a login flow that binds with an empty password, or treats an anonymous bind as success, authenticates an attacker who supplied no valid credential. You find these by tracing untrusted input into filter and DN construction, and by reading the bind logic for the empty-credential and anonymous cases. ## When to use - An application builds LDAP search filters or distinguished names from request input. - Authentication is performed by binding to a directory with user-supplied credentials. - A directory lookup uses a search base or scope influenced by untrusted input. ## Scope check …

How to install
mdr add unboundcompute/security-agent-skills/hunting-ldap-injection-and-bind-trust@sha256:13fc27272b1c096aThe line at the top of this page pins the label git:20260826.c45369b, 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.
