Insecure Temporary File Vulnerability in Apache Ant
CVE-2020-1945

6.3MEDIUM

Key Information:

Vendor: Apache
Status: Apache Ant
Vendor: CVE Published:; 14 May 2020

What is CVE-2020-1945?

Apache Ant versions from 1.1 to 1.9.14 and from 1.10.0 to 1.10.7 utilize the default temporary directory defined by the Java property java.io.tmpdir for various operations. This practice poses a risk of leaking sensitive user information. Furthermore, tasks such as fixcrlf and replaceregexp can inadvertently copy files from this insecure temporary directory back into the build environment, enabling a potential attacker to inject altered source files into the build process. This flaw underscores the importance of secure file handling practices within development tools.
