How to Fix CVE-2014-4172

To remediate this vulnerability, upgrade all affected DotNetCasClient dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

DotNetCasClient fixed: 1.0.2 
Upgrade DotNetCasClient to 1.0.2
org.jasig.cas:cas-client fixed: 3.3.2 
<dependency>
    <groupId>org.jasig.cas</groupId>
    <artifactId>cas-client</artifactId>
    <version>3.3.2</version>
</dependency>
jasig/phpcas fixed: 1.3.3 
Upgrade jasig/phpcas to 1.3.3
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for DotNetCasClient

How to Check if You Are Affected

To determine whether your application is affected by CVE-2014-4172, inspect your project dependencies for DotNetCasClient:

inspect dependencies for DotNetCasClient

Analyze the terminal output to locate any version of DotNetCasClient in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.0.2), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection'), where the product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. In DotNetCasClient, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

A URL parameter injection vulnerability was found in the back-channel ticket validation step of the CAS protocol in Jasig Java CAS Client before 3.3.2, .NET CAS Client before 1.0.2, and phpCAS before 1.3.3 that allow remote attackers to inject arbitrary web script or HTML via the (1) service parameter to validation/AbstractUrlBasedTicketValidator.java or (2) pgtUrl parameter to validation/Cas20ServiceTicketValidator.java.
