Background
Apache Ant is a Java-based build tool used for automating software build processes. It provides a set of tasks and libraries to compile, test, and package applications. The vulnerability identified as CVE-2020-1945 affects Apache Ant versions 1.1 to 1.9.14 and 1.10.0 to 1.10.7. This vulnerability arises from the use of the default temporary directory, java.io.tmpdir, for various tasks in Apache Ant. As a result, sensitive information may be leaked. Additionally, the fixcrlf and replaceregexp tasks in Apache Ant copy files from the temporary directory back into the build tree, which can allow an attacker to inject modified source files into the build process.
Vulnerability Detail
The vulnerability in Apache Ant allows an attacker to potentially access sensitive information due to the use of the default temporary directory. This can lead to unauthorized disclosure of data and compromise the integrity of the build process. The fixcrlf and replaceregexp tasks further exacerbate the issue by allowing modified source files to be injected into the build process. This vulnerability has a CVSS score of 6.3, indicating a moderate severity level.
How To Fix
Fixed versions by release line
The minimum fixed version depends on the release line you run.
-
>= 1.1, < 1.9.151.9.15 -
>= 1.10.0, < 1.10.81.10.8

Workaround
As a workaround, users can manually specify a different temporary directory for Apache Ant by setting the java.io.tmpdir system property to a secure location. This can be done by modifying the Ant build script or by setting the property in the Ant command line. For example, in a Unix-like environment, the following command can be used: ant -Djava.io.tmpdir=/path/to/secure/directory
Conclusion
In conclusion, the vulnerability CVE-2020-1945 in Apache Ant exposes sensitive data and allows for potential injection of modified source files. It is crucial to upgrade to the fixed versions of Apache Ant to mitigate this vulnerability. Alternatively, users can implement the provided workaround by specifying a secure temporary directory.
