How to Fix CVE-2014-8684

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

codeigniter/framework fixed: 3.0.0 
Upgrade codeigniter/framework to 3.0.0
kohana/core fixed: 3.3.3 
Upgrade kohana/core to 3.3.3
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 codeigniter/framework

How to Check if You Are Affected

To determine whether your application is affected by CVE-2014-8684, inspect your project dependencies for Codeigniter/framework:

inspect dependencies for codeigniter/framework

Analyze the terminal output to locate any version of Codeigniter/framework in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.0.0), your application is affected.

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

Technical Details

Source Advisory Statement

CodeIgniter before 3.0 and Kohana 3.2.3 and earlier and 3.3.x through 3.3.2 make it easier for remote attackers to spoof session cookies and consequently conduct PHP object injection attacks by leveraging use of standard string comparison operators to compare cryptographic hashes.
