    OMERO.web provides a web based client and plugin infrastructure.

This issue has been patched in version 5.29.2. A workaround involves disabling the Forgot password option in OMERO.web using the omero.web.show_forgot_password configuration property.

  • Oct 14, 2021OMERO.web provides a web based client and plugin infrastructure.CVE-2021-41132 · Other software · ome · reported by GitHubCritical 9.8

    OMERO.web provides a web based client and plugin infrastructure. In versions prior to 5.11.0, 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 cross-site scripting possibilities with specially crafted input to a variety of fields. This issue is patched in version 5.11.0. There are no known workarounds aside from upgrading.

  • Mar 23, 2021OMERO.web is open source Django-based software for managing microscopy imaging.CVE-2021-21377 · Other software · ome · reported by GitHubMedium 4.8

    OMERO.web is open source Django-based software for managing microscopy imaging. OMERO.web before version 5.9.0 supports redirection to a given URL after performing login or switching the group context. These URLs are not validated, allowing redirection to untrusted sites. OMERO.web 5.9.0 adds URL validation before redirecting. External URLs are not considered valid, unless specified in the omero.web.redirect_allowed_hosts setting.

  • Mar 23, 2021OMERO.web is open source Django-based software for managing microscopy imaging.CVE-2021-21376 · Other software · ome · reported by GitHubMedium 6.4

    OMERO.web is open source Django-based software for managing microscopy imaging. OMERO.web before version 5.9.0 loads various information about the current user such as their id, name and the groups they are in, and these are available on the main webclient pages. This represents an information exposure vulnerability. Some additional information being loaded is not used by the webclient and is being removed in this release. This is fixed in version 5.9.0.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
