How to Fix GHSA-62f6-h68r-3jpw

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: 2.2.9
Upgrade zendframework/zendframework to 2.2.9
zendframework/zendframework fixed: 2.3.4
Upgrade zendframework/zendframework to 2.3.4
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 GHSA-62f6-h68r-3jpw, 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 2.2.9), 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-384: Session Fixation, where authenticating a user, or otherwise establishing a new user session, without invalidating any existing session identifier gives an attacker the opportunity to steal authenticated sessions. 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

`Zend\Session` session validators do not work as expected if set prior to the start of a session. For instance, the following test case fails (where `$this->manager` is an instance of `Zend\Session\SessionManager`): ``` $this ->manager ->getValidatorChain() ->attach('session.validate', array(new RemoteAddr(), 'isValid')); $this->manager->start(); $this->assertSame( array( 'Zend\Session\Validator\RemoteAddr' =3D> '', ), $_SESSION['__ZF']['_VALID'] ); ``` The implication is that subsequent calls to `Zend\Session\SessionManager#start()` (in later requests, assuming a session was created) will not have any validator metadata attached, which causes any validator metadata to be re-built from scratch, thus marking the session as valid. An attacker is thus able to simply ignore session validators such as RemoteAddr or HttpUserAgent, since the "signature" that these validators check against is not being stored in the session.
