How to Fix CVE-2015-5161

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

zendframework/zendframework fixed: 2.4.6 
Upgrade zendframework/zendframework to 2.4.6
zendframework/zendframework fixed: 2.5.2 
Upgrade zendframework/zendframework to 2.5.2
zendframework/zendframework1 fixed: 1.12.14 
Upgrade zendframework/zendframework1 to 1.12.14
zendframework/zendxml fixed: 1.0.1 
Upgrade zendframework/zendxml to 1.0.1
zendframework/zendframework fixed: 1.12.14 
Upgrade zendframework/zendframework to 1.12.14
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 zendframework/zendframework

How to Check if You Are Affected

To determine whether your application is affected by CVE-2015-5161, inspect your project dependencies for Zendframework/zendframework:

inspect dependencies for zendframework/zendframework

Analyze the terminal output to locate any version of Zendframework/zendframework in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.4.6), 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-776: Improper Restriction of Recursive Entity References in DTDs ('XML Entity Expansion'), where the product uses xml documents and allows their structure to be defined with a document type definition (dtd), but it does not properly control the number of recursive definitions of entities. In Zendframework/zendframework, 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

The `Zend_Xml_Security::scan` in ZendXml before 1.0.1 and Zend Framework before 1.12.14, 2.x before 2.4.6, and 2.5.x before 2.5.2, when running under PHP-FPM in a threaded environment, allows remote attackers to bypass security checks and conduct XML external entity (XXE) and XML entity expansion (XEE) attacks via multibyte encoded characters.
