CVE-2021-32751 is a high-severity vulnerability affecting gradle gradle. It was published on July 20, 2021 and has a CVSS 3.1 base score of 7.5 (HIGH).
This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.
Technical Description
Gradle is a build tool with a focus on build automation. In versions prior to 7.2, start scripts generated by the `application` plugin and the `gradlew` script are both vulnerable to arbitrary code execution when an attacker is able to change environment variables for the user running the script. This may impact those who use `gradlew` on Unix-like systems or use the scripts generated by Gradle in thieir application on Unix-like systems. For this vulnerability to be exploitable, an attacker needs to be able to set the value of particular environment variables and have those environment variables be seen by the vulnerable scripts. This issue has been patched in Gradle 7.2 by removing the use of `eval` and requiring the use of the `bash` shell. There are a few workarounds available. For CI/CD systems using the Gradle build tool, one may ensure that untrusted users are unable to change environment variables for the user that executes `gradlew`. If one is unable to upgrade to Gradle 7.2, o
Remediation
