CVE-2022-39834
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 · uneditedA stored XSS vulnerability was discovered in adminweb/ra/viewendentity.jsp in PrimeKey EJBCA through 7.9.0.2. A low-privilege user can store JavaScript in order to exploit a higher-privilege user.
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 · high confidenceA stored XSS vulnerability exists in the viewendentity.jsp page of PrimeKey EJBCA's Registration Authority (RA) web interface. A low-privilege user can inject malicious JavaScript code into entity data fields, which gets stored in the system. When a higher-privilege administrator views this entity data, the stored JavaScript executes in their browser session, potentially allowing session hijacking or administrative actions.

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.
-
Identify installed EJBCA versionLocate the EJBCA version file or check the admin interface version display. Common locations include the WAR file manifest, version.properties, or the About page in the EJBCA admin web interface.Affected if The installed version is 7.9.0.2 or earlier (the vulnerable version range)
-
Confirm RA web interface is deployedVerify the Registration Authority (RA) web interface is deployed and accessible. Check application server configuration or attempt to access the RA portal URL.Affected if The RA web interface is exposed and accessible to users
-
Check for low-privilege RA user accessReview user roles and access controls in EJBCA to determine if low-privilege users have access to create or modify entity data through the RA interface.Affected if Low-privilege users can access entity data creation or modification functions in the RA
-
Inspect entity data for injected contentQuery the entity data database tables or use the admin interface to review stored entity records for unexpected script tags, JavaScript event handlers, or encoded payloads in user-supplied fields.Affected if Malicious scripts, HTML tags, or XSS payloads are found stored in entity data fields
If the installed EJBCA version is 7.9.0.2 or earlier and the RA web interface is accessible to low-privilege users, the environment is affected by this stored XSS vulnerability.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply output encoding/sanitization to all user-supplied data displayed in viewendentity.jsp, and implement proper input validation on data ingestion. Upgrade to EJBCA version 7.9.0.3 or later which contains the security fix.
