OMERO.web provides a web based client and plugin infrastructure. Prior to version 5.29.2, if an error occurred when resetting a users 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.
The product generates an error message that includes sensitive information about its environment, users, or associated data.
The sensitive information may be valuable information on its own (such as a password), or it may be useful for launching other, more serious attacks. The error message may be created in different ways:
An attacker may use the contents of error messages to help launch another, more focused attack. For example, an attempt to exploit a path traversal weakness (CWE-22) might yield the full pathname of the installed application. In turn, this could be used to select the proper number of “..” sequences to navigate to the targeted file. An attack using SQL injection (CWE-89) might not initially succeed, but an error message could reveal the malformed query, which would expose query logic and possibly even passwords or other sensitive information used within the query.
