RCE in Alfresco Community Edition 5.2 via malicious Solr configuration and JMX deserialization

IdentifiersCVE-2019-14224CWE-502· Deserialization of Untrusted Data

CVE-2019-14224 affects Alfresco Community Edition 5.2 201707. The issue is described as an exploit chain involving multiple Alfresco components that can lead to remote code execution on the victim machine. Exploitation requires an attacker to upload malicious Solr configuration files, after which the victim initiates a JMX connection. The attacker then serves a Java object to the victim, resulting in unsafe deserialization and subsequent code execution. Based on the available description, the core weakness is insecure deserialization in the context of a JMX-mediated interaction triggered through malicious Solr configuration.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation results in remote code execution on the Alfresco host. This allows an attacker to execute arbitrary code in the security context of the affected application or associated service, which can lead to full compromise of the application instance, access to hosted content and credentials, installation of persistence mechanisms, and potential lateral movement depending on the privileges of the compromised process and surrounding environment.

Mitigation

If you can’t patch tonight, do this now.

As interim mitigation, restrict or disable any capability that allows untrusted users to upload or modify Solr configuration files. Limit network connectivity so the Alfresco host cannot initiate JMX connections to attacker-controlled systems, and restrict JMX exposure to trusted management networks only. Monitor for unexpected Solr configuration changes, anomalous outbound JMX connections, and suspicious Java deserialization activity. Apply least-privilege controls to the Alfresco and related service accounts to reduce post-exploitation impact.

Remediation

Patch, then assume compromise.

Upgrade to a vendor-fixed release of Alfresco Community Edition or apply the vendor-provided security update addressing CVE-2019-14224, if available. Because the exploit chain depends on the ability to upload malicious Solr configuration and trigger a JMX-based deserialization path, remediation should also include removing or restricting any functionality that permits untrusted Solr configuration uploads and ensuring JMX-related components are configured securely in accordance with vendor guidance.
