Security Bulletin: IBM Notes is affected with Open Source Apache Struts Vulnerabilities (CVE-2016-1181, CVE-2016-1182)

Security Bulletin


Summary


IBM Expeditor version 6.2.3 contains Apache Struts. If an application is developed that leverages taglibs, this application can itself be vulnerable while running on top of Notes Client. Initial proposal is to remove struts as Apache Struts is for 3rd-party development and not a library that is used by Notes, Sametime, etc.
