How to Fix CVE-2021-41132

To remediate this vulnerability, upgrade all affected Omero web dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

omero-web fixed: 5.11.0 
pip install omero-web>=5.11.0
omero-figure fixed: 4.4.1 
pip install omero-figure>=4.4.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show omero-web

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2021-41132, inspect your installed packages using pip:

pip show omero-web

Analyze the terminal output to locate any version of Omero web in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 5.11.0), your application is affected.

Note: The pip show omero-web command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-116: Improper Encoding or Escaping of Output, where the product prepares a structured message for communication with another component, but encoding or escaping of the data is either missing or done incorrectly. as a result, the intended structure of the message is not preserved. In Omero web, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Background A variety of templates do not perform proper sanitization through HTML escaping. Due to the lack of sanitization and use of ``jQuery.html()``, there are a whole host of XSS possibilities with specially crafted input to a variety of fields. ### Impact OMERO.web before 5.11.0 and OMERO.figure before 4.4.1. ### Patches Users should upgrade OMERO.web to 5.11.0 or higher and OMERO.figure to 4.4.1 or higher.
