CVE-2022-22809 is a CWE-306 vulnerability, categorized as a Missing Authentication for Critical Function. This vulnerability allows modifications of the touch configurations in an unauthorized manner when an attacker attempts to modify these configurations. The affected products include spaceLYnk (versions V2.6.2 and prior), Wiser for KNX (formerly homeLYnk) (versions V2.6.2 and prior), and fellerLYnk (versions V2.6.2 and prior). The severity of this vulnerability is classified as medium, with a CVSS score of 5.3.
Organizations utilizing these products face inherent risks, including potential unauthorized access to configuration settings, which could impact the functionality and security of the devices. The attack vector is network-based, with low complexity and no privileges required for exploitation, making it accessible to a broader range of potential attackers.
The urgency for defenders is high. Organizations should prioritize patching immediately to prevent unauthorized modifications and ensure the integrity of their configurations. No public exploit has been confirmed, but the ease of exploitation emphasizes the importance of swift remediation.
For those affected, the remediation involves updating to the latest firmware versions beyond V2.6.2. Schneider Electric has provided advisories detailing the necessary patches.
Vulnerability Details
The vulnerability allows modifications of touch configurations without proper authentication, which is a critical failure in security design. The CVSS score of 5.3 indicates a medium severity, and the vulnerability affects Schneider Electric's products, including spaceLYnk, Wiser for KNX, and fellerLYnk, all versions prior to 2.6.2. This vulnerability was published on February 9, 2022, and is categorized under CWE-306.
Technical Analysis
The root cause of this vulnerability is the lack of authentication for critical functions, which allows unauthorized users to alter touch configurations. The attack vector is network-based, and the complexity is low, requiring no privileges or user interaction. The impacts include partial integrity loss, as attackers can modify configurations without detection, while confidentiality and availability remain unaffected.
Risk & Impact Analysis
The risk to organizations includes unauthorized access to touch configurations, potentially compromising device functionality and security. This vulnerability may lead to broader attack surfaces, especially if exploited in networks where other critical systems are present. Given the CVSS score and the potential for exploitation, organizations should address this vulnerability in their priority patch cycle.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The affected versions include all versions up to and including 2.6.2 of spaceLYnk, Wiser for KNX, and fellerLYnk. Organizations should ensure they are operating versions beyond this to mitigate the vulnerability.
Mitigation & Remediation
