Vulnerabilities

Bio-Formats versions up to and including 8.3.0 perform unsafe Java deserialization of attacker-controlled memoization cache files (.bfmemo) during image processing. The loci.formats.Memoizer class automatically loads and deserializes memo files associated with images without validation, integrity checks, or trust enforcement. An attacker who can supply a crafted .bfmemo file alongside an image can trigger deserialization of untrusted data, which may result in denial of service, logic manipulation, or potentially remote code execution in environments where suitable gadget chains are present on the classpath.

OMERO.web provides a web based client and plugin infrastructure. Prior to version 5.29.2, if an error occurred when resetting a user's password using the Forgot Password option in OMERO.web, the error message displayed on the Web page can disclose information about the user. 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.

OMERO.web provides a web based client and plugin infrastructure. There is currently no escaping or validation of the `callback` parameter that can be passed to various OMERO.web endpoints that have JSONP enabled. This vulnerability has been patched in version 5.26.0.

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.

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.

OMERO.server before 5.6.1 allows attackers to bypass the security filters and access hidden objects via a crafted query.

OMERO.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.

OMERO before 5.6.1 makes the details of each user available to all users.

In Open Microscopy Environment OMERO.server 5.0.0 through 5.6.0, the reading of files from imported image filesets may circumvent OMERO permissions restrictions. This occurs because the Bio-Formats feature allows an image file to have embedded pathnames.

The Open Microscopy Environment OMERO.web version prior to 5.4.7 contains an Information Exposure Through Log Files vulnerability in the login form and change password form that can result in User's password being revealed. Attacker can log in as that user. This attack appear to be exploitable via an attacker reading the web server log. This vulnerability appears to have been fixed in 5.4.7.

In OMERO 5.3.3 or earlier a user could create an OriginalFile and adjust its path such that it now points to another user's file on the underlying filesystem, then manipulate the user's data.
