CVE-2022-26866
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedDell PowerStore Versions before v2.1.1.0. contains a Stored Cross-Site Scripting vulnerability. A high privileged network attacker could potentially exploit this vulnerability, leading to the storage of malicious HTML or JavaScript codes in a trusted application data store. When a victim user accesses the data store through their browsers, the malicious code gets executed by the web browser in the context of the vulnerable web application. Exploitation may lead to information disclosure, session theft, or client-side request forgery.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceDell PowerStore versions before v2.1.1.0 contain a stored Cross-Site Scripting (XSS) vulnerability. A high-privileged network attacker can inject malicious HTML or JavaScript code into the application's trusted data store. When victim users access this compromised data through their web browsers, the embedded scripts execute within the context of the vulnerable web application, potentially leading to information disclosure, session theft, or client-side request forgery.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Determine PowerStoreOS versionAccess the PowerStore management interface or CLI and retrieve the current PowerStoreOS version number. This is typically found in the system settings, About section, or by running the appropriate version command.Affected if The installed PowerStoreOS version is below 2.1.1.0
-
Verify web application is accessibleConfirm that the PowerStore web management interface is network-accessible. Check if the HTTPS portal is exposed and reachable by users.Affected if The web interface is accessible and the version is below 2.1.1.0
-
Confirm high-privileged attacker accessReview access controls and audit logs to determine if a network attacker could have obtained high-privileged credentials to inject malicious scripts into the application's data store.Affected if High-privileged attacker access is possible and the version is below 2.1.1.0
A user is affected if their PowerStoreOS version is below 2.1.1.0 and the web interface is accessible to trigger the stored XSS when users view compromised data.
