CVE-2011-1183: Apache Tomcat

Medium severity, CVSS 5.8. EPSS: 6.2% chance of exploitation in the next 30 days.

Apache Tomcat 7.0.11, when web.xml has no login configuration, does not follow security constraints, which allows remote attackers to bypass intended access restrictions via HTTP requests to a meta-data complete web application. NOTE: this vulnerability exists because of an incorrect fix for CVE-2011-1088 and CVE-2011-1419.

Affected products

• Apache Tomcat: version 7.0.11 only
