Apache Tomcat autoDeploy attribute security bypass

tomcat-autodeploy-security-bypass (55856) The risk level is classified as MediumMedium Risk

Description:

Apache Tomcat could allow a remote attacker to bypass security restrictions, caused by an error when setting the autoDeploy attribute for directories placed in the hosts's appBase. Following a failed undeploy, some arbitrary files are autodeployed with improper access restrictions. A remote attacker could exploit this vulnerability to bypass security restrictions to gain unauthorized access to normally restricted files.
