Command Injection

  • Vulnerable module: org.apache.maven.shared:maven-shared-utils
  • Introduced through: org.apache.maven:maven-core@3.6.0

Detailed paths

  • Introduced through: openapi-tools/swagger-maven-plugin@openapi-tools/swagger-maven-plugin#524970448a09180b46e9085dc00418b177cf0833 org.apache.maven:maven-core@3.6.0 org.apache.maven.shared:maven-shared-utils@3.2.1
    Remediation: Upgrade to org.apache.maven:maven-core@3.8.2.

Overview

org.apache.maven.shared:maven-shared-utils is a functional replacement for plexus-utils in Maven.

Affected versions of this package are vulnerable to Command Injection. The Commandline class can emit double-quoted strings without proper escaping, allowing shell injection attacks. The BourneShell class should unconditionally single-quote emitted strings (including the name of the command itself being quoted), with {{'"'"'}} used for embedded single quotes, for maximum safety across shells implementing a superset of POSIX quoting rules.

This is a similar issue to SNYK-JAVA-ORGCODEHAUSPLEXUS-31522

Remediation

Upgrade org.apache.maven.shared:maven-shared-utils to version 3.3.3 or higher.

Overview

commons-io:commons-io is a The Apache Commons IO library contains utility classes, stream implementations, file filters, file comparators, endian transformation classes, and much more.

Affected versions of this package are vulnerable to Directory Traversal via calling the method FileNameUtils.normalize using an improper string like //../foo or \\..\foo, which may allow access to files in the parent directory.

Details

A Directory Traversal attack (also known as path traversal) aims to access files and directories that are stored outside the intended folder. By manipulating files with "dot-dot-slash (../)" sequences and its variations, or by using absolute file paths, it may be possible to access arbitrary files and directories stored on file system, including application source code, configuration, and other critical system files.

Directory Traversal vulnerabilities can be generally divided into two types:

  • Information Disclosure: Allows the attacker to gain information about the folder structure or read the contents of sensitive files on the system.

st is a module for serving static files on web pages, and contains a vulnerability of this type. In our example, we will serve files from the public route.

If an attacker requests the following URL from our server, it will in turn leak the sensitive private key of the root user.

curl http://localhost:8080/public/%2e%2e/%2e%2e/%2e%2e/%2e%2e/%2e%2e/root/.ssh/id_rsa

Note %2e is the URL encoded version of . (dot).

  • Writing arbitrary files: Allows the attacker to create or replace existing files. This type of vulnerability is also known as Zip-Slip.

One way to achieve this is by using a malicious zip archive that holds path traversal filenames. When each filename in the zip archive gets concatenated to the target extraction folder, without validation, the final path ends up outside of the target folder. If an executable or a configuration file is overwritten with a file containing malicious code, the problem can turn into an arbitrary code execution issue quite easily.

The following is an example of a zip archive with one benign file and one malicious file. Extracting the malicious file will result in traversing out of the target folder, ending up in /root/.ssh/ overwriting the authorized_keys file:

2018-04-15 22:04:29 .....           19           19  good.txt
2018-04-15 22:04:42 .....           20           20  ../../../../../../root/.ssh/authorized_keys

Remediation

Upgrade commons-io:commons-io to version 2.7 or higher.
