CVE-2023-5222 Scanner

Viessmann Vitogate 300 is a component used in energy systems to facilitate the interoperability of heating systems. The product is widely utilized in residential and commercial buildings to ensure efficient energy transfer between different heating technologies. Developed by Viessmann, a prominent entity in the energy solutions market, this gateway assists in energy monitoring and control. It is critical for seamless communication between diverse technological interfaces within complex energy systems. Users depend on its functionality to maximize energy use and integration efficiency across their infrastructure. The product is regularly updated to meet evolving energy standards and technology compatibility.

The vulnerability identified in the Viessmann Vitogate 300 is due to the presence of hard-coded passwords in its firmware. This security flaw allows unauthorized users to gain access to the device by exploiting the embedded credentials. Hard-coded passwords are critical weaknesses as they can be easily exploited by attackers who become aware of them, bypassing standard authentication mechanisms. The implications of this vulnerability are severe, as it compromises the security of the entire system connected through the Vitogate. Organizations deploying such devices stand at risk of unauthorized access and potential system manipulation. Addressing root causes and advocating secure coding practices are essential to prevent such vulnerabilities.

Technically speaking, the vulnerability manifests itself at the authentication phase within the Web Management Interface of the Vitogate 300. The device permits login using specific usernames and passwords set as defaults in the firmware. Attackers exploiting this flaw perform unauthorized actions by utilizing default credentials like 'vitomaster' or 'vitogate' with corresponding passwords such as 'viessmann1917'. Upon successful exploitation, attackers achieve access that can lead to critical malfunctions or manipulation of connected systems. The endpoints of concern are those processing login requests, where insufficient hardening allows exploitation. Adequately securing these endpoints requires firmware updates or more robust security controls in place.

If exploited, the hard-coded password vulnerability could result in unauthorized access to sensitive functions of the Vitogate 300, leading to system tampering or denial of service. Attackers could manipulate settings, compromise data integrity, and interrupt service, adversely impacting business operations. Such breaches infringe on privacy, risk data disclosure, and may incur financial and reputational damage. Furthermore, unauthorized access to the configuration interface could allow attackers to pivot to other network resources, escalating impacts beyond the initially accessed system. Proactive measures are crucial to protect against possible exploitations impacting connected infrastructure and processes.
