Strengthening Business Foundations: Tech Support and Cybersecurity in Houston

Impress Computer Solutions, a trusted IT provider in Houston, is alerting businesses about a newly discovered high-severity flaw impacting select industrial routers. The vulnerability, if left unaddressed, could expose critical systems to exploitation, underscoring the importance of proactive cybersecurity measures.

 

The Threat: Exploitation of Default Credentials

Cybersecurity researchers have identified a vulnerability, tracked as CVE-2024-12856 (CVSS score: 7.2), affecting certain industrial router models. This flaw is an operating system (OS) command injection bug that can be exploited if attackers gain access using default credentials.

While the flaw requires authentication, many businesses fail to change default credentials, leaving devices exposed to unauthenticated OS command execution.

Key Findings:

  • The vulnerability impacts router models F3x24 and F3x36.
  • Exploitation allows attackers to launch reverse shells for persistent remote access.
  • Threat actors have been leveraging this flaw alongside previous vulnerabilities, such as CVE-2019-12168, to conduct widespread attacks.

Houston Businesses at Risk

Data from threat intelligence sources reveals over 15,000 internet-facing devices vulnerable to exploitation. Impress Computer Solutions warns that businesses using industrial routers could unknowingly expose their networks to malicious actors, risking data breaches and operational disruptions.

How the Exploits Work

Attackers exploit the routers via the /apply.cgi endpoint, targeting the adj_time_year parameter when adjusting system time. This method enables OS command injection, allowing unauthorized changes and malware deployment.

Attack Characteristics:

  • Exploitation attempts originate from known malicious IP addresses.
  • Attacks often result in the download of Mirai-like payloads, which can disrupt operations.
  • Evidence suggests these attacks have been ongoing since November 2024.
