Marten has an injection vulnerability in its full-text search regConfig parameter

9.8 / 10
Critical
Network Low None None Unchanged High High High

Summary

Marten's full-text search APIs interpolated the user-supplied regConfig parameter directly into the generated SQL without parameterization or validation, making every code path that exposes regConfig to untrusted input a SQL injection sink.

Affected APIs

IQuerySession.SearchAsync<T>(string searchTerm, string regConfig, ...)

IQuerySession.PlainTextSearchAsync<T>(...)

IQuerySession.PhraseSearchAsync<T>(...)

IQuerySession.WebStyleSearchAsync<T>(...)

IQuerySession.PrefixSearchAsync<T>(...)

IQueryable<T>.Where(x => x.Search(term, regConfig)) and the matching PlainTextSearch / PhraseSearch / WebStyleSearch / PrefixSearch extension methods

Details

In the affected versions, FullTextWhereFragment renders the WHERE-clause SQL by string interpolation:

private string Sql => $"to_tsvector('{_regConfig}'::regconfig, {_dataConfig}) @@ {_searchFunction}('{_regConfig}'::regconfig, ?)";

_regConfig arrives unchanged from the public API surface above. Any value containing a single quote terminates the SQL literal and lets an attacker append arbitrary PostgreSQL.

Confirmed exploit shapes (with regConfig set to attacker-controlled input)

| Goal | Payload | | --- | --- | | Time-based blind | english'::text); SELECT pg_sleep(5); -- | | Information disclosure | english'; SELECT version(); -- | | DDL execution | english'; DROP TABLE mt_doc_article; -- |

All five overloads listed above produced SQL containing the verbatim payload.

Impact

Confidentiality: an attacker can append arbitrary SELECT statements and exfiltrate database contents through error channels, response timing, or — if the application surfaces query results — directly.

Integrity / Availability: DDL, UPDATE, DELETE, and pg_sleep-style denial-of-service payloads succeed under the same vector. Concrete impact depends on the database role used by the Marten connection string.

Precondition: the calling application must forward attacker-controlled input into the regConfig parameter (e.g. a ?lang= query string mapped to regConfig). Applications that hard-code regConfig to a compile-time constant are not exploitable.

Patches

Fixed in Marten 8.36.1 (and forward) by #4343.

FullTextWhereFragment now validates regConfig against ^[a-zA-Z_][a-zA-Z0-9_]*(\.[a-zA-Z_][a-zA-Z0-9_]*)?$ (a simple PostgreSQL identifier, optionally schema-qualified, capped at NAMEDATALEN-1 per side) and throws ArgumentException for anything else. The default value ("english"), schema-qualified configs ("pg_catalog.english"), and the standard PostgreSQL text-search configurations all continue to work.

Workarounds

If users cannot upgrade immediately, do one of the following at the application boundary:

Hard-code regConfig to a compile-time constant ("english", "simple", …) and never accept it from request input.

Validate any externally-sourced regConfig value before passing it to Marten — e.g. against the same regex as the patch (^[a-zA-Z_][a-zA-Z0-9_]*(\.[a-zA-Z_][a-zA-Z0-9_]*)?$) or against an allowlist of PostgreSQL configurations the application actually uses.

Drop the regConfig argument from the call site so Marten falls back to the safe default.
