Overview<\/strong><\/p>\n

CVE-2025-26481 is a critical vulnerability found in Dell PowerScale OneFS versions 9.4.0.0 through 9.9.0.0, allowing unprivileged attackers to potentially exploit and cause a denial of service. The flaw is of particular concern to organizations utilizing these versions of Dell PowerScale OneFS, as successful exploitation could compromise the system or even lead to data leakage.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-26481
\nSeverity: High (7.5)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: System compromise and potential data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Dell PowerScale OneFS | 9.4.0.0 – 9.9.0.0<\/p>\n

How the Exploit Works<\/strong><\/p>\n

This vulnerability allows a remote unprivileged attacker to exploit the uncontrolled resource consumption flaw in Dell PowerScale OneFS. By sending a series of network requests that consume a significant amount of system resources, the attacker could cause a denial of service, leading to system downtime and potentially compromising system security.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Here’s a conceptual example of how the vulnerability might be exploited using network requests:<\/p>\n

POST \/vulnerable\/resource\/consumption HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/json\n{ \"resource_request\": \"consume_infinite_resource\" }<\/code><\/pre>\n
In this example, the attacker sends a request that triggers the resource consumption vulnerability, causing the system to become unresponsive or crash.<\/p>\n
Mitigation and Recommendations<\/strong><\/p>\n
Dell has released patches to address this vulnerability. Users of affected versions of Dell PowerScale OneFS are advised to apply the vendor’s patch as soon as possible. As a temporary mitigation, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used to filter out malicious traffic that attempts to exploit this vulnerability.<\/p>\n","protected":false},"excerpt":{"rendered":"
