CVE-2020-7932
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 · uneditedOMERO.web before 5.6.3 optionally allows sensitive data elements (e.g., a session key) to be passed as URL query parameters. If an attacker tricks a user into clicking a malicious link in OMERO.web, the information in the query parameters may be exposed in the Referer header seen by the target. Information in the URL path such as object IDs may also be exposed.
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 confidenceOMERO.web before version 5.6.3 contains an information disclosure vulnerability where sensitive data such as session keys can be passed as URL query parameters. When users are tricked into clicking malicious links, these query parameters may be exposed in the Referer header sent to third-party sites, and URL path information like object IDs may also be disclosed.

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 OMERO.web installation and versionLocate the OMERO.web installation directory and determine the installed version number (typically via package manager, pip show, or version file in the installation)Affected if The installed version is any version prior to 5.6.3 (e.g., 5.6.2, 5.6.1, 5.6.0, or earlier)
-
Confirm version against vulnerable rangeCompare your identified version to the affected range: versions less than 5.6.3 are vulnerableAffected if The version number is lower than 5.6.3 (for example, 5.6.2 or any earlier release)
-
Inspect URL query parameters for session dataExamine HTTP requests and application logs to determine whether session keys, authentication tokens, or other sensitive identifiers are being transmitted as URL query parameters rather than in headers or cookiesAffected if Session keys, authentication tokens, or similar sensitive data appear in URL query strings (the portion after the ? in URLs)
You are affected if your OMERO.web version is lower than 5.6.3 and your application passes session keys or authentication data in URL query parameters that could leak via Referer headers.
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.
From vendor data5.6.3
Upgrade OMERO.web to version 5.6.3 or later, which eliminates the practice of passing sensitive data in URL query parameters.
