  • If you are currently unable to upgrade to these Pentaho versions, the only way to defend against this vulnerability and block the vector that permits returning arbitrary files and execution as JSP is to upgrade to Apache Tomcat 9.0.31, 8.5.51 or 7.0.100 or later. Options such as the secret option of Tomcat (required by default since Tomcat 8.5.51 and 9.0.31) can just be added as a separate parameter at the end of ProxyPass or BalancerMember.

    However, the connector does not start with Protocol handler start failed. Edit the C:Program FilesApache Software FoundationTomcat 8.5confserver.xml file and add the secretRequiredfalse option to the AJP/1.3 connector.

In Apache Tomcat 9.0.0.M1 to 9.0.0.30, 8.5.0 to 8.5.50 and 7.0.0 to 7.0.99, the AJP Connector is enabled by default, meaning it can listen on all configured IP addresses. If such connections are available to an attacker, they may be exploited in ways that may represent a risk. Tomcat treats AJP connections as having higher trust than, for example, a similar HTTP connection. It is mainly used in a cluster or reverse proxy scenario where web servers communicate with application servers or servlet containers. The AJP is a binary protocol used by the Apache Tomcat webserver to communicate with the servlet container that sits behind the webserver using TCP connections. A recent vulnerability in Tomcat’s Apache JServ Protocol (AJP) Connector ( CVE-2020-1938) has raised concern among some Pentaho customers that they may be exposed to a security risk, specifically because of the vulnerability’s potential use for remote code execution.Īfter careful review, Pentaho recommends that an upgrade to Tomcat 8.5.51 is necessary if AJP connectors are enabled.
