CVE-2022-30065

CVSS v2.0

10

High

VectorAV:N/AC:L/Au:N/C:C/I:C/A:C
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.
