| Vector | AV: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.Exploit
