Siemens RUGGEDCOM RST2428P Integer Overflow or Wraparound (CVE-2025-6052)

low Tenable OT Security Plugin ID 505423

Synopsis

The remote OT asset is affected by a vulnerability.

Description

A flaw was found in how GLibs GString manages memory when adding data to strings. If a string is already very large, combining it with more input can cause a hidden overflow in the size calculation. This makes the system think it has enough memory when it doesnt. As a result, data may be written past the end of the allocated memory, leading to crashes or memory corruption.

This plugin only works with Tenable.ot.
