DescriptionNVD

Unsafe deserialization vulnerability in MixPHP Framework 2.x thru 2.2.17. The sync-invoke client (Connection.php:76) calls unserialize() on data received from the server response, enabling client-side RCE if connecting to a malicious server.

AnalysisAI

Client-side remote code execution affects MixPHP Framework 2.x through 2.2.17 when sync-invoke clients connect to attacker-controlled servers. The vulnerability enables malicious servers to execute arbitrary code on connecting clients through unsafe deserialization of server responses (CWE-502). …

RemediationAI

Within 24 hours: Audit all MixPHP deployments to identify instances using versions 2.0-2.2.17 and document external server endpoints they connect to. Within 7 days: Implement network segmentation to restrict MixPHP clients from connecting to untrusted external servers; apply input validation and disable unsafe deserialization where framework configuration permits. …
