Certain versions of Apache Struts are affected by a cross-site scripting vulnerability when debug mode is switched on or when JSPs are exposed in a production environment. These versions of Apache Struts are being used in IDENTIKEY Authentication Server. Even though the debug mode is switched off, some JSPs are directly accessible on the IAS server.
- IDENTIKEY (Virtual) Appliance versions 3.8 and earlier
- IDENTIKEY Authentication Server versions 3.8 and earlier
The Apache Struts project announced in October 2015 that Apache Struts version 2.0.0 up to version 18.104.22.168 are affected by a cross-site scripting vulnerability when debug mode is switched on or when JSP files are exposed in a production environment. Two CVE identifiers have been assigned to these vulnerabilities:
- CVE-2015-5169: Apache Struts is vulnerable to a cross-site scripting vulnerability when debug mode is enabled. A remote attacker could exploit this vulnerability using a specially-crafted URL to execute script in a victim's web browser within the security context of the hosting Web site, once the URL is clicked.
- CVE-2015-2992: Apache Struts is vulnerable to a cross-site scripting vulnerability when accessing JSP files directly. A remote attacker could exploit this vulnerability using a specially-crafted URL to execute script in a victim's Web browser within the security context of the hosting Web site, once the URL is clicked.
Vulnerability CVE-2015-5169 is not applicable to the IDENTIKEY Authentication Service since debug mode is disabled by default.
Vulnerability CVE-2015-2992 is applicable since there are some JSP files that are directly accessible using a browser.
|CVSS Base Score: 4.3|

OneSpan will fix these vulnerabilities in the following upcoming releases:
- IDENTIKEY (Virtual) Appliance 3.9
- IDENTIKEY Authentication Server 3.9
Customers can protect their IAS-installation by making a modification to the web.xml configuration file. This modification will prohibit direct access to JSP's that should not be directly accessible.
In order to change the configuration, the following security-constraint and security-role must be appended to the web-app body in the web.xml configuration file:
No direct JSP access
Don't assign users to this role
Customers with a maintenance contract can obtain fixed product releases from MyMaintenance. Customers without a maintenance contract should contact their local sales representative.
