Apache Struts isCancelled() security bypass
| struts-iscancelled-security-bypass (25612) |  Medium Risk |
Description:
Struts could allow a remote attacker to bypass security restrictions. If an attacker sends a request with a "org.apache.struts.taglib.html.Constants.CANCEL" parameter, the attacker could cause validation to be canceled without being detected by Struts applications that do not check for isCancelled(). This could allow the attacker to bypass security restrictions and gain unauthorized access to restricted content.
Platforms Affected:
- Apache, Struts 1.2.8
- RedHat, Enterprise Linux 4 WS
- RedHat, Linux Advanced Workstation 2.1 Itanium
- RedHat, RHEL Application Server 2
Remedy:
Upgrade to the latest version of Apache Struts (1.2.9 or later) available from the Apache Struts Project Web page. See References.
Consequences:
Bypass Security
