CVE-2023-39810 [HIGH] CWE-22 busybox: CPIO command of Busybox allows attackers to execute a directory traversal
busybox: CPIO command of Busybox allows attackers to execute a directory traversal
An issue in the CPIO command of Busybox v1.33.2 allows attackers to execute a directory traversal.
A flaw was found in the BusyBox tool. This issue occurs in the cpio command of BusyBox and may allow attackers to execute a directory traversal. If untrusted archives are extracted, this can result in files written outside of the destination directory or files being overwritten that contain configuration in the form of shell scripts such as ~/.bashrc or scripts that enable login from a remote side such as the ~/.ssh/authorized_keys file.
Statement: This issue did not affect the versions of Busybox as shipped with Red Hat Enterprise Linux 6.
Mitigation: Change the default behavior to ignore relative file nam

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.
