CVE-2020-9524
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 · uneditedCross Site scripting vulnerability on Micro Focus Enterprise Server and Enterprise developer, affecting all versions prior to version 5.0 Patch Update 8. The vulnerability could allow an attacker to trigger administrative actions when an administrator viewed malicious data left by the attacker (stored XSS) or followed a malicious link (reflected XSS).
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 confidenceCross Site Scripting (XSS) vulnerability in Micro Focus Enterprise Server and Enterprise Developer affecting all versions before 5.0 Patch Update 8. The vulnerability exists in two forms: stored XSS (where malicious data is left for administrators to view) and reflected XSS (delivered via malicious links). Successful exploitation could allow attackers to trigger administrative actions by targeting authenticated administrators.

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.
-
Verify Micro Focus Enterprise Server or Enterprise Developer is installedCheck the system for Enterprise Server or Enterprise Developer installation directories or listed programs/services. Look for Micro Focus installation folders in standard locations or check installed programs list.Affected if Either product is installed on the system
-
Determine the installed version numberLocate version information for the installed product, typically found in product documentation, about dialog, or installation metadata. Compare the version to the 5.0 baseline.Affected if Version is 5.0 or higher but the Patch Update level is unknown or below 8
-
Identify the Patch Update levelCheck the product's built-in version display, release notes, or patch information for the specific Patch Update number (PU1-PU7 indicates vulnerability; PU8 or later is fixed).Affected if Patch Update level is before 8, meaning Update 7 or earlier, or no patch update information is available indicating pre-PU8 state
-
Confirm web administration interface is accessibleVerify the Enterprise Server or Enterprise Developer web-based administration console is enabled and reachable. This is the attack vector for both stored and reflected XSS.Affected if Web administration interface is enabled and accessible to users or attackers on the network
You are affected if Micro Focus Enterprise Server or Enterprise Developer version 5.0 with Patch Update 7 or earlier is installed and the web administration interface is enabled.
