Vulnerability Details
Unraid 6.8.0 allows authentication bypass. This means that an attacker could potentially gain unauthorized access to the system without valid credentials. The vulnerability is classified as high severity with a CVSS score of 7.5, indicating a significant risk to confidentiality but no impact on integrity or availability.
The vulnerability was disclosed on March 16, 2020, and the affected product is Unraid version 6.8.0. The vulnerability falls under CWE-697, which emphasizes the importance of proper authentication mechanisms.
Technical Analysis
The root cause of this vulnerability stems from inadequate authentication validation within Unraid 6.8.0. Attackers may leverage this flaw over a network with low attack complexity and no privileges required. User interaction is not necessary for exploitation, making this vulnerability particularly dangerous.
The confidentiality impact of this vulnerability is high, as it allows unauthorized users to gain access to sensitive system settings. However, there is no impact on integrity or availability, meaning that while attackers can access the system, they cannot alter its fundamental operations or disrupt its availability.
Risk & Impact Analysis
Real-world deployment of Unraid 6.8.0 carries significant risk due to this vulnerability. Attackers exploiting this flaw can gain administrative access, leading to potential data breaches or system manipulation. The blast radius could be substantial, particularly in environments where Unraid is used to manage sensitive data.
Given the high CVSS score and active exploitation status, organizations must assess their exposure to this vulnerability. The urgency of remediation is critical, and organizations should prioritize applying patches as soon as they are available.
