Unchecked JNDI lookups in GeoTools (CVE-2022-24818)

The recent log4shell vulnerability has brought to our attention that unchecked JNDI lookups are inadvisable. We have isolated the JNDI lookup code responsible in GeoTools and reported the vulnerability as GHSA-jvh2-668r-g75x / CVE-2022-24818.

To address this issue we are pleased to introduce the jndiLookup(String) function:

DataSource dataSource = (DataSource) GeoTools.jndiLookup(name);

This method is provides safe look-ups by default (limited to no-schema and java lookups). You may override this policy for your application by supplying a JNDI Name validator.

Please update your application to one of the patched releases: GeoTools 26.4, GeoTools 25.6 or GeoTools 24.6 (and following the update instructions).

The approach used (limiting lookups to no-schema and java lookups) is the same one taken by the Log4J project. You may wish to review your application for any use of InitialContext.lookup(fixedName), and consider making use of jndiLookup(String) as a resolution. For more information see the GeoTools utility class documentation, and javadocs.

GeoTools 25.5 released

The GeoTools team is pleased to announce the release GeoTools 25.5:

GeoTools 25.5 is published to repo.osgeo.org for direct build integration. This release is made in conjunction with GeoServer 2.19.5. The GeoTools team is grateful to Astun Technology for allowing Ian Turton the time to prepare this release.

Bug Fixes

This is a maintenance release and includes the following bug fixes and tasks: 
  • GEOT-7073 GeoPackage store fails to use spatial indexes when multiple BBOX filters are used at the same time
  • GEOT-7071 GetFeatureInfo in WMSLayer has problems in transinformation of I,J params
It's worth noting that GeoTools does not directly use Log4J, but adopts the Java Logging Framework. However, it has a plugin allowing to redirect all the logging calls to Log4J, for which we have made a fix in GEOT-7038. Please read more about the vulnerability assessment of Log4J 1.2.17 vulnerabilities in this GeoServer blog post.
