Dell PowerScale OneFS, versions prior to 9.12.0.0, contains an improper check for unusual or exceptional conditions vulnerability. A high privileged attacker with local access could potentially exploit this vulnerability, leading to denial of service. The CVSS score for this vulnerability is 4.1, categorizing it as medium severity. Organizations using affected versions should be aware of the potential risk to their systems.
Risk to organizations includes potential denial of service, which could disrupt business operations. As the vulnerability requires high privileges and local access to exploit, the immediate threat may be limited; however, any local access could lead to significant service disruptions.
Organizations should prioritize patching immediately. The vulnerability has been analyzed and reported, but there is currently no known public exploit available, which indicates that the situation could change if the vulnerability becomes widely recognized.
To mitigate the risk, organizations should ensure they are running the latest version of Dell PowerScale OneFS. Regular updates and monitoring for vulnerability disclosures are essential to maintain security posture.
Vulnerability Details
Dell PowerScale OneFS, versions prior to 9.12.0.0, contains an improper check for unusual or exceptional conditions vulnerability. This issue falls under CWE-754: Improper Check for Unusual or Exceptional Conditions. The official description notes that a high privileged attacker with local access can exploit this vulnerability, leading to denial of service.
The CVSS score of this vulnerability is 4.1, which classifies it as medium severity. The attack vector is local, requiring high privileges to exploit, and it has a high attack complexity. The availability impact is rated high, meaning that a successful exploit could lead to significant disruption.
Technical Analysis
The root cause of this vulnerability stems from inadequate checks for unusual or exceptional conditions in the Dell PowerScale OneFS software. Attackers may exploit this vulnerability when they have local access and sufficient privileges.
The attack vector is local, and the complexity is rated high, indicating that it may not be easily exploited without the necessary access and privileges. User interaction is not required, which further exposes the risk. The confidentiality and integrity impacts are rated as none, while the availability impact is high, emphasizing the potential for service denial.
Risk & Impact Analysis
The real-world deployment risk associated with this vulnerability is significant, particularly for organizations that utilize Dell PowerScale OneFS in critical environments. The potential for denial of service could disrupt business operations, leading to financial losses and reputational damage.
The blast radius potential is limited to systems where the vulnerable versions are deployed. However, if exploited, the impact could be severe, resulting in downtime and loss of access to critical data and services.
Urgency assessment based on the CVSS score indicates that organizations should address this vulnerability in their priority patch cycle. Although it is not currently actively exploited, the potential for exploitation exists.
