An issue was discovered in Alfresco Community Edition 5.2 201707.

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.

Weakness class (CWE)

CWE-502 · Deserialization of Untrusted Data

CVSS vector

CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H

nvd-primary

Root cause

Data received over the network is deserialized into the language’s native object format without verifying its source. Code paths inside the object can be triggered during deserialization.
