Synopsis

An application running on a remote web server host is affected by a vulnerability

Description

The version of Splunk installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the SVD-2025-1103 advisory.

 - jackson-core contains core low-level incremental (streaming) parser and generator abstractions used by Jackson Data Processor. In versions prior to 2.15.0, if a user parses an input file and it has deeply nested data, Jackson could end up throwing a StackoverflowError if the depth is particularly large.
 jackson-core 2.15.0 contains a configurable limit for how deep Jackson will traverse in an input document, defaulting to an allowable depth of 1000. jackson-core will throw a StreamConstraintsException if the limit is reached. jackson-databind also benefits from this change because it uses jackson-core to parse JSON inputs. As a workaround, users should avoid parsing input files from untrusted sources.
 (CVE-2025-52999)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade Splunk Enterprise to versions 10.0.1, 9.4.5, 9.3.7, 9.2.9, or higher.
