The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers). An example of a network attack is an attacker causing a denial of service by sending a specially crafted TCP packet across a wide area network (e.g., CVE-2004-0230).
Attack Complexity
Low
AC
The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Privileges Required
None
PR
The attacker is unauthenticated prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction
None
UI
The vulnerable system can be exploited without interaction from any human user, other than the attacker. Examples include: a remote attacker is able to send packets to a target system a locally authenticated attacker executes code to elevate privileges
Scope
Unchanged
S
An exploited vulnerability can only affect resources managed by the same security authority. In the case of a vulnerability in a virtualized environment, an exploited vulnerability in one guest instance would not affect neighboring guest instances.
Confidentiality
High
C
There is total information disclosure, resulting in all data on the system being revealed to the attacker, or there is a possibility of the attacker gaining control over confidential data.
Integrity
High
I
There is a total compromise of system integrity. There is a complete loss of system protection, resulting in the attacker being able to modify any file on the target system.
Availability
High
A
There is a total shutdown of the affected resource. The attacker can deny access to the system or data, potentially causing significant loss to the organization.
The Apache Struts group is pleased to announce that Struts 2.3.14.1 is
available as a "General Availability" release. The GA designation is
our highest quality grade.
Apache Struts 2 is an elegant, extensible framework for creating
enterprise-ready Java web applications. The framework is designed to
streamline the full development cycle, from building, to deploying, to
maintaining applications over time.
Two security issues were solved with this release:
* Showcase app vulnerability allows remote command execution
* A vulnerability, present in the includeParams attribute of the URL
and Anchor Tag, allows remote command execution
All developers are strongly advised to update existing Struts 2
applications to Struts 2.3.14.1.
Struts 2.3.14.1 is available in a full distribution or as separate
library, source, example and documentation distributions, from the
releases page. The release is also available through the central Maven
repository under Group ID "org.apache.struts". The release notes are
available online.
The 2.3.x series of the Apache Struts framework has a minimum
requirement of the following specification versions: Servlet API 2.4,
JSP API 2.0, and Java 5.
Should any issues arise with your use of any version of the Struts
framework, please post your comments to the user list, and, if
appropriate, file a tracking ticket.
