CVE-ID: CVE-2015-5345

CWE-ID: CWE-200

Exploitation vector: Network

Exploit availability: No

Vulnerable software:
Apache Tomcat
Server applications / Web servers
Oracle Linux
Operating systems & Components / Operating system

Vendor: Apache Foundation

Description

The vulnerability allows a remote attacker to obtain potentially sensitive information.

When accessing a directory protected by a security constraint with a URL that did not end in a slash, Tomcat would redirect to the URL with the trailing slash thereby confirming the presence of the directory before processing the security constraint. It was therefore possible for a user to determine if a directory existed or not, even if the user was not permitted to view the directory.

Successful exploitation of the vulnerability may allow a remote attacker to confirm existence of directories on the system.

Mitigation
Install the latest version Apache Tomcat 6.0.45, 7.0.68, 8.0.30 or 9.0.0.M3
