Package

maven org.apache.tomcat:tomcat-catalina (Maven)

Affected versions

>= 11.0.0-M1, < 11.0.3

>= 10.1.0-M1, < 10.1.35

>= 9.0.0.M1, < 9.0.99

Path Equivalence: ‘file.Name’ (Internal Dot) leading to Remote Code Execution and/or Information disclosure and/or malicious content added to uploaded files via write enabled Default Servlet in Apache Tomcat.

This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.2, from 10.1.0-M1 through 10.1.34, from 9.0.0.M1 through 9.0.98.

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 was 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

Users are recommended to upgrade to version 11.0.3, 10.1.35 or 9.0.98, which fixes the issue.
