Busybox · Busybox · CVE-2022-30065
**Name of the Vulnerable Software and Affected Versions**
Busybox versions 1.35-x
**Description**
The issue is related to a use-after-free in the awk applet of Busybox, which can lead to denial of service and possibly code execution when processing a crafted awk pattern in the `copyvar` function. This allows a remote attacker to access confidential data, compromise its integrity, and cause a denial of service.
**Recommendations**
For Busybox version 1.35-x, consider disabling the `copyvar` function in the awk applet as a temporary workaround until a patch is available. Restrict access to the awk applet to minimize the risk of exploitation. Avoid using the `copyvar` function when processing awk patterns until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
