CVE-2025-66484
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 · uneditedIBM Aspera Shares 1.9.9 through 1.11.0 is vulnerable to stored cross-site scripting. This vulnerability allows users to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session.
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 confidenceIBM Aspera Shares versions 1.9.9 through 1.11.0 contains a stored cross-site scripting (XSS) vulnerability in its web interface. Attackers can embed malicious JavaScript code into the Web UI that persists and executes when other users view the affected content, potentially exposing credentials or session tokens within trusted sessions.

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 installed Aspera Shares versionAccess the Aspera Shares admin console or check version files in the installation directory. Typically, the version is displayed in the About section of the admin UI or can be found in a version file within the installation path.Affected if The installed version is 1.9.9, 1.10.0, 1.10.1, 1.10.2, 1.10.x, or 1.11.0 (any version >= 1.9.9 but < 1.11.1)
-
Confirm web interface is enabledVerify that the Aspera Shares web UI service is running and accessible. Check if the web server process is active and the UI port (commonly 443 or 8080) is listening.Affected if The Aspera Shares web interface is exposed and accessible to users
The environment is affected if IBM Aspera Shares version 1.9.9 through 1.11.0 is installed and the web interface is enabled, as this version range contains the stored XSS vulnerability in the web UI.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scoped1.11.1
Upgrade to a patched version provided by IBM. Until a patch is available, implement output encoding and input validation on all user-supplied content rendered in the web UI.
1.11.1 or later
