CVE-2026-40010: Posssible session fixation attack in Apache Wicket. in Apache Software Foundation Apache Wicket
Missing invocation of Servlet http web request method changeSessionId after session binding can be exploited for a session fixation attack in Apache Wicket. This issue affects Apache Wicket: from 8.0.0 through 8.17.0, 9.0.0, from 10.0.0 through 10.8.0. Users are recommended to upgrade to version 10.9.0, which fixes the issue.
AI Analysis
Technical Summary
The vulnerability in Apache Wicket arises from the failure to call the Servlet API method changeSessionId after session binding, which is necessary to prevent session fixation attacks. Affected versions include 8.0.0 through 8.17.0, 9.0.0, and 10.0.0 through 10.8.0. This flaw allows an attacker to set or reuse a session identifier, potentially hijacking a user's session. The Apache Software Foundation has addressed this issue in version 10.9.0 by ensuring proper invocation of changeSessionId.
Potential Impact
Successful exploitation of this vulnerability can lead to session fixation, allowing attackers to impersonate legitimate users by reusing or fixing session IDs. This compromises confidentiality and integrity of user sessions but does not affect availability. The CVSS score of 9.1 reflects high impact on confidentiality and integrity with no privileges or user interaction required.
Mitigation Recommendations
Users should upgrade Apache Wicket to version 10.9.0 or later, where the issue is fixed by proper invocation of the changeSessionId method after session binding. No other mitigation or temporary workaround is indicated. Patch status is confirmed by the vendor advisory recommending upgrade to 10.9.0.
