Description

A code injection vulnerability exists in one of the webpages in GE Reason RT430, RT431 & RT434 GNSS clocks in firmware versions prior to version 08A06 that could allow an authenticated remote attacker to execute arbitrary code on the system.

Understanding This Vulnerability

This Common Vulnerabilities and Exposures (CVE) entry provides detailed information about a security vulnerability that has been publicly disclosed. CVEs are standardized identifiers assigned by MITRE Corporation to track and catalog security vulnerabilities across software and hardware products.

The severity rating (CRITICAL) indicates the potential impact of this vulnerability based on the CVSS (Common Vulnerability Scoring System) framework. Higher severity ratings typically indicate vulnerabilities that could lead to more significant security breaches if exploited. Security teams should prioritize remediation efforts based on severity, exploit availability, and the EPSS (Exploit Prediction Scoring System) score, which predicts the likelihood of exploitation in the wild.

If this vulnerability affects products or systems in your infrastructure, we recommend reviewing the affected products section, checking for available patches or updates from vendors, and implementing recommended workarounds or solutions until a permanent fix is available. Organizations should also monitor security advisories and threat intelligence feeds for updates about active exploitation of this vulnerability.

Workarounds

GE recommends users evaluate current risk and implement appropriate network security mitigation measures as follows. The following mitigation actions do not ensure complete security but should be considered until the affected time synchronization product is upgraded:
Use strong network and physical security protection to prevent an attacker from reaching the local network where Reason RT43X clocks are normally installed.
Block TCP/IP Ports 80 and 443 to block the HTTP/HTTPS access to web interface with Reason RT43X products, avoiding all the vulnerabilities. This TCP/IP port blocking should be limited to the Ethernet port interface where the Reason RT43X clock is connected (e.g., using Access Control List (ACL)). Otherwise, other HTTP/HTTPS applications may be affected.
Minimize network exposure for all control system devices and/or systems and ensure they are not accessible from the Internet.
Analyze security events to early detect unexpected traffic/communication.

Solutions

GE strongly recommends users of Reason RT43X products update their units to firmware Version 08A06 or greater to resolve these issues. The firmware update addresses both vulnerabilities as described in the Reason RT43X 08A06 Release Notes.
