Dell EMC iDRAC9 firmware versions prior to 4.40.00.00 contain a Time-of-check Time-of-use (TOCTOU) race condition vulnerability. A remote authenticated attacker could potentially exploit this vulnerability to gain elevated privileges when a user with higher privileges is simultaneously accessing iDRAC through the web interface. This vulnerability has a CVSS score of 5.9, indicating a medium severity level, which highlights the importance of addressing it in a timely manner.
The exploitation of this vulnerability could lead to unauthorized access to sensitive settings and functions within the iDRAC9 interface, thereby posing significant risks to organizations that utilize affected systems. As the exploitation status remains unconfirmed, it is crucial for organizations to take immediate action to mitigate any potential risks.
Organizations should prioritize patching immediately to reduce exposure to this vulnerability. Proper remediation strategies should be part of the organization's security posture to prevent possible exploitation.
With the ongoing evolution of cyber threats, maintaining updated firmware is a critical component of security hygiene. Organizations should regularly review and update their security practices to stay ahead of potential threats.
Vulnerability Details
The vulnerability is classified under CWE-367, which pertains to Time-of-check Time-of-use (TOCTOU) race conditions. The official CVSS score from the NVD is 7.1, indicating a high severity classification due to its potential impact on confidentiality, integrity, and availability. This vulnerability affects Dell EMC iDRAC9 versions prior to 4.40.00.00, and its publication date was April 30, 2021.
Technical Analysis
The root cause of this vulnerability lies in a race condition, where the timing of checks and uses is exploited by attackers. The attack vector is network-based, and the complexity is considered high due to the need for user interaction. Attackers require low privileges to exploit this vulnerability, making it accessible to users with basic access rights.
The impacts of a successful exploitation could result in high integrity impact, as attackers may alter critical settings within the iDRAC9 interface, while confidentiality and availability impacts are rated low.
Risk & Impact Analysis
Risk to organizations includes the potential for unauthorized access to system configurations and sensitive data, which could facilitate further attacks or data breaches. The blast radius of this vulnerability is particularly concerning for organizations that rely heavily on Dell EMC infrastructure, as many critical functions may be affected.
Organizations should address this vulnerability in their priority patch cycle to mitigate risks associated with potential exploit attempts. The urgency for remediation is heightened by the nature of the vulnerability and the ease with which it could be exploited.
