CVE-2022-24818

GeoTools is an open source Java library that provides tools for geospatial data. The GeoTools library has a number of data sources that can perform unchecked JNDI lookups, which in turn can be used to perform class deserialization and result in arbitrary code execution. Similar to the Log4J case, the vulnerability can be triggered if the JNDI names are user-provided, but requires admin-level login to be triggered. The lookups are now restricted in GeoTools 26.4, GeoTools 25.6, and GeoTools 24.6. Users unable to upgrade should ensure that any downstream application should not allow usage of remotely provided JNDI strings.

Weakness

The product constructs all or part of an expression language (EL) statement in a framework such as a Java Server Page (JSP) using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended EL statement before it is executed.

Affected Software

Potential Mitigations

• If user-controlled data must be added to an expression interpreter, one or more of the following should be performed:
