struts-iscancelled-security-bypass (25612) The risk level is classified as MediumMedium Risk

This could allow the attacker to bypass security restrictions and gain unauthorized access to restricted content.

  • RedHat, Enterprise Linux 4 WS
  • RedHat, Linux Advanced Workstation 2.1 Itanium
  • RedHat, RHEL Application Server 2
