Technical ContextAI · show details

This vulnerability is classified as Deserialization of Untrusted Data (CWE-502), which allows attackers to execute arbitrary code through malicious serialized objects. An issue was discovered in Alfresco Community Edition 5.2 201707. By leveraging multiple components in the Alfresco Software applications, an exploit chain was observed that allows an attacker to achieve remote code execution on the victim machine. The attacker must upload malicious Solr configuration files and then receive a JMX connection from the victim, and serve a Java object that results in deserialization and code execution. Affected products include: Alfresco.

Attack Technique

Insecure deserialization occurs when an application converts serialized data (a stream of bytes representing an object's state) back into a living object without proper validation.

Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
