OGNL expression evaluation can lead to arbitrary code execution, as was seen in the past with a similar Apache Struts vulnerability (CVE-2019-0230), and this case is no different. Refer to Confluence Security Advisory - for patch, upgrade or suggested workaround information.Recently, a new OGNL (Object-Graph Navigation Language) expression injection vulnerability was discovered in the Atlassian Confluence framework.
For this first example I will use ( ) which is written in Python

Capture the request log in request using a web proxy, I’d be using BurpSuite.Ĥ. Verify connectivity to the Confluence serverĢ. By sending a specially-crafted request, an attacker could exploit this vulnerability to execute arbitrary code on the system.Ĭonfluence Server and Data Center versions before version 6.13.23, from version 6.14.0 before 7.4.11, from version 7.5.0 before 7.11.6, and from version 7.12.0 before 7.12.5 are affected by this vulnerability.Ītlassian Confluence Data Center 7.12.4 Vulnerable pathsġ. With confluence, we can capture project requirements, assign tasks to specific users, and manage several calendars at once.Ītlassian Confluence Server and Center code could allow a remote attacker to execute arbitrary code on the system, caused by a webwork OGNL injection flaw.
