Alluxio · Alluxio · CVE-2023-38889
**Name of the Vulnerable Software and Affected Versions**
Alluxio versions 2.9.3 and earlier
**Description**
An issue in Alluxio allows an attacker to execute arbitrary code via a crafted script to the `username` parameter of `lluxio.util.CommonUtils.getUnixGroups(java.lang.String)`. This enables the attacker to potentially gain unauthorized access and control.
**Recommendations**
For Alluxio versions 2.9.3 and earlier, as a temporary workaround, consider restricting access to the `lluxio.util.CommonUtils.getUnixGroups(java.lang.String)` function until a patch is available. Additionally, avoid using the `username` parameter in the affected function to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this issue.
