SSA-787941: Denial of Service Vulnerability in RUGGEDCOM ROS devices

Publication Date:	2022-11-08
Last Update:	2025-08-12
Current Version:	V1.5
CVSS v3.1 Base Score:	5.3

SUMMARY

RUGGEDCOM ROS-based devices are vulnerable to a denial of service attack (Slowloris). By sending partial HTTP requests nonstop, with none completed, the affected web servers will be waiting for the completion of each request, occupying all available HTTP connections. The web server recovers by itself once the attack ends.

Siemens has released new versions for several affected products and recommends to update to the latest versions. Siemens is preparing further fix versions and recommends specific countermeasures for products where fixes are not, or not yet available.

GENERAL SECURITY RECOMMENDATIONS

As a general security measure, Siemens strongly recommends to protect network access to devices with appropriate mechanisms. In order to operate the devices in a protected IT environment, Siemens recommends to configure the environment according to Siemens' operational guidelines for Industrial Security (Download: https://www.siemens.com/cert/operational-guidelines-industrial-security), and to follow the recommendations in the product manuals. Additional information on Industrial Security by Siemens can be found at: https://www.siemens.com/industrialsecurity

PRODUCT DESCRIPTION

RUGGEDCOM ROS-based devices, typically switches and serial-to-Ethernet devices, are used to connect devices that operate in harsh environments such as electric utility substations and traffic control cabinets.

VULNERABILITY DESCRIPTION

Un-/Collapse All

This chapter describes all vulnerabilities (CVE-IDs) addressed in this security advisory. Wherever applicable, it also documents the product-specific impact of the individual vulnerabilities.

Vulnerability CVE-2022-39158

Affected devices improperly handle partial HTTP requests which makes them vulnerable to slowloris attacks.

This could allow a remote attacker to create a denial of service condition that persists until the attack ends.
