Link to public exploit:

Vulnerability description

The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists due to insufficient validation of user-supplied input when handling file uploads via HTTP PUT requests. A remote attacker can send a specially crafted HTTP PUT request to the server and gain access to sensitive information or even execute arbitrary code.

If all of the following were true, a malicious user was able to view security sensitive files and/or inject content into those files:

• writes enabled for the default servlet (disabled by default)
• support for partial PUT (enabled by default)
• a target URL for security sensitive uploads that is a sub-directory of a target URL for public uploads
• attacker knowledge of the names of security sensitive files being uploaded
• the security sensitive files also being uploaded via partial PUT

If all of the following were true, a malicious user was able to perform remote code execution:

• writes enabled for the default servlet (disabled by default)
• support for partial PUT (enabled by default)
• application was using Tomcat's file based session persistence with the default storage location
• application included a library that may be leveraged in a deserialization attack
