Siemens RuggedCom Rox Uncontrolled Recursion (CVE-2025-9714)

medium Tenable OT Security Plugin ID 505472

Synopsis

The remote OT asset is affected by a vulnerability.

Description

Uncontrolled recursion inXPath evaluationin libxml2 up to and including version 2.9.14 allows a local attacker to cause a stack overflow via crafted expressions. XPath processing functions `xmlXPathRunEval`, `xmlXPathCtxtCompile`, and `xmlXPathEvalExpr` were resetting recursion depth to zero before making potentially recursive calls. When such functions were called recursively this could allow for uncontrolled recursion and lead to a stack overflow. These functions now preserve recursion depth across recursive calls, allowing recursion depth to be controlled.

This plugin only works with Tenable.ot.
