This is a separate install from WebSphere Application Server. You only need to apply this if you use the Edge Caching Proxy. Vulnerability Details CVEID: CVE-2017-1503 DESCRIPTION: IBM WebSphere Application Server is vulnerable to HTTP response splitting attacks. A remote attacker could exploit this vulnerability using specially-crafted URL to cause the server to return a split response, once the URL is clicked. This would allow the attacker to perform further attacks, such as Web cache poisoning, cross-site scripting, and possibly obtain sensitive information. CVSS Base Score: 6.1 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 129578 for the current score Affected Products and Versions IBM WebSphere Application Server Edge Caching Proxy Version 7.0, 8.0, 8.5, & 9.0 Remediation/Fixes The recommended solution is to apply the Fix Pack or PTF for each named product as soon as practical. Fix: Apply an Interim Fix, Fix Pack or PTF containing APAR PI82587 if you use the Edge Caching Proxy component (separate install from WebSphere Application Server) as noted below: For IBM WebSphere Application Server For V9.0.0.0 through 9.0.0.4: o Upgrade to 9.0.0.3 fix pack level then apply Interim Fix PI82587 - -- OR o Upgrade to 9.0.0.4 fix pack level then apply Interim Fix PI82587 - -- OR o Apply Fix Pack 5 (9.0.0.5), or later.

The custom startup script will not pull the umask from the server.xml. This may cause some log files to have different permissions then expected. Vulnerability Details CVEID: CVE-2017-1382 DESCRIPTION: IBM WebSphere Application Server might create files using the default permissions instead of the customized permissions when custom startup scripts are used. A local attacker could exploit this to gain access to files with an unknown impact. CVSS Base Score: 5.1 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/ 127153 for the current score Affected Products and Versions IBM Campaign V7.0, V8.0, V8.5, V9.0 Remediation/Fixes If you have a umask defined in your server.xml and you use custom startup scripts, you should verify that your log files have the correct permissions that you expect. You will need to manually change these files permissions if they are not as expected. The interim fix below will only prevent this from happening in the future. It will not change your current log file permissions. The recommended solution is to apply the interim fix, Fix Pack or PTF containing APAR PI79343 for each named product as soon as practical. For WebSphere Application Server traditional and WebSphere Application Server Hypervisor Edition: For V9.0.0.0 through 9.0.0.4: - - Upgrade to minimal fix pack levels as required by interim fix and then apply Interim Fix PI79343 - --OR-- - - Apply Fix Pack 9.0.0.5 or later. For V8.5.0.0 through 8.5.5.11: - - Upgrade to minimal fix pack levels as required by interim fix and then apply Interim Fix PI79343 - --OR-- - - Apply Fix Pack 8.5.5.12 or later.
