GeoServer OGC Filter SQL Injection Vulnerabilities

CVE-2023-25157 → View on GitHub ↗ View on CVE.org ↗ View on NVD ↗

Description

Impact

GeoServer includes support for the OGC Filter expression language and the OGC Common Query Language (CQL) as part of the Web Feature Service (WFS) and Web Map Service (WMS) protocols. CQL is also supported through the Web Coverage Service (WCS) protocol for ImageMosaic coverages.

SQL Injection Vulnerabilities have been found with:

  • PropertyIsLike filter, when used with a String field and any database DataStore, or with a PostGIS DataStore with encode functions enabled
  • strEndsWith function, when used with a PostGIS DataStore with encode functions enabled
  • strStartsWith function, when used with a PostGIS DataStore with encode functions enabled
  • FeatureId filter, when used with any database table having a String primary key column and when prepared statements are disabled
  • jsonArrayContains function, when used with a String or JSON field and with a PostGIS or Oracle DataStore (GeoServer 2.22.0+ only)
  • DWithin filter, when used with an Oracle DataStore

Patches

  • GeoSever 2.21.4
  • GeoServer 2.22.2
  • GeoServer 2.20.7
  • GeoServer 2.19.7
  • GeoServer 2.18.7

Workarounds

  1. Disabling the PostGIS Datastore encode functions setting to mitigate strEndsWith, strStartsWith vulnerabilities (Like filters have no mitigation, if there is a string field in the feature type published).
  2. Enabling the PostGIS DataStore preparedStatements setting to mitigate the FeatureId vulnerability.

Base score Version Severity Vector
9.8 3.1 —
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
