Siemens Sicam Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

critical Tenable.ot Plugin ID 500423
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Description

A vulnerability has been identified in SICAM WEB firmware for SICAM A8000 RTUs (All versions < V05.30). The login screen does not sufficiently sanitize input, which enables an attacker to generate specially crafted log messages. If an unsuspecting victim views the log messages via the web browser, these log messages might be interpreted and executed as code by the web application. This Cross-Site-Scripting (XSS) vulnerability might compromize the confidentiality, integrity and availability of the web application.
