CVE-2020-14988: 
Bloomreach Experience Manager vulnerability analysis and mitigation

CVE-2020-14988 is a cross-site scripting (XSS) vulnerability discovered in Bloomreach Experience Manager (brXM) versions 4.1.0 through 14.2.2. The vulnerability was discovered in June 2020 and publicly disclosed in March 2021 (Bloomreach Blog).

The vulnerability exists in the login portals at both /cms and /cms/console endpoints of the web application. The XSS vulnerability was found in the 'loginmessage' parameter and could be triggered by unauthenticated users. However, logged-in users were not affected as they would be redirected before the 'loginmessage' is displayed (Bloomreach Blog).

This vulnerability allows unauthenticated attackers to execute arbitrary web scripts or HTML code in the context of the login portal. This could potentially lead to theft of user credentials or session tokens if users interact with the malicious payload (Bloomreach Blog).

The vulnerability was fixed in a security update released by Bloomreach in October 2020. Users are advised to update to the latest stable version to address this vulnerability (Bloomreach Blog).

Bloomreach, which powers over $200 billion in digital commerce experiences and serves major organizations including the Dutch Government, Dutch Police, and Dutch Railways, responded promptly to the vulnerability report and coordinated the disclosure process (Bloomreach Blog).
