The add_probe function in modutils/modprobe.c in BusyBox before 1.23.0 allows local users to bypass intended restrictions on loading kernel modules via a / (slash) character in a module name, as demonstrated by an "ifconfig /usbserial up" command or a "mount -t /snd_pcm none /" command.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

The remote Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3935-1 advisory.

    Tyler Hicks discovered that BusyBox incorrectly handled symlinks inside tar archives. If a user or     automated system were tricked into processing a specially crafted tar archive, a remote attacker could     overwrite arbitrary files outside of the current directory. This issue only affected Ubuntu 14.04 LTS and     Ubuntu 16.04 LTS. (CVE-2011-5325)

    Mathias Krause discovered that BusyBox incorrectly handled kernel module loading restrictions. A local     attacker could possibly use this issue to bypass intended restrictions. This issue only affected Ubuntu     14.04 LTS. (CVE-2014-9645)

    It was discovered that BusyBox incorrectly handled certain ZIP archives. If a user or automated system     were tricked into processing a specially crafted ZIP archive, a remote attacker could cause BusyBox to     crash, leading to a denial of service. This issue only affected Ubuntu 14.04 LTS and Ubuntu 16.04 LTS.
    (CVE-2015-9261)

    Nico Golde discovered that the BusyBox DHCP client incorrectly handled certain malformed domain names.

(CVE-2016-2147)

    Nico Golde discovered that the BusyBox DHCP client incorrectly handled certain 6RD options. A remote     attacker could use this issue to cause the DHCP client to crash, leading to a denial of service, or     possibly execute arbitrary code. This issue only affected Ubuntu 14.04 LTS and Ubuntu 16.04 LTS.
    (CVE-2016-2148)

    It was discovered that BusyBox incorrectly handled certain bzip2 archives. If a user or automated system     were tricked into processing a specially crafted bzip2 archive, a remote attacker could cause BusyBox to     crash, leading to a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu     14.04 LTS and Ubuntu 16.04 LTS. (CVE-2017-15873)

    It was discovered that BusyBox incorrectly handled tab completion. A local attacker could possibly use     this issue to execute arbitrary code. This issue only affected Ubuntu 14.04 LTS and Ubuntu 16.04 LTS.
    (CVE-2017-16544)

    It was discovered that the BusyBox wget utility incorrectly handled certain responses. A remote attacker     could use this issue to cause BusyBox to crash, resulting in a denial of service, or possibly execute     arbitrary code. (CVE-2018-1000517)

    It was discovered that the BusyBox DHCP utilities incorrectly handled certain memory operations. A remote     attacker could possibly use this issue to access sensitive information. (CVE-2018-20679, CVE-2019-5747)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

-The following issues are fixed by this update: CVE-2014-9645: do not allow / in module names to avoid loading bad modules (bnc#914660)

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Busybox was updated to fix one security issue.

The following vulnerability was fixed :

  - CVE-2014-9645: fixed a potential modprobe filter     bypassing rule by filtering / (boo#914660)

The remote host is affected by the vulnerability described in GLSA-201503-13 (BusyBox: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in BusyBox.  Please review       the CVE identifiers referenced below for details.
  Impact :

    A context-dependent attacker can load kernel modules without privileges       by nullifying enforced module       prefixes. Execution of arbitrary files or a Denial of Service can be       caused through the included vulnerable LZO library.
  Workaround :

    There is no known workaround at this time.

Updated busybox packages fix security vulnerability :

The modprobe command in busybox before 1.23.0 uses the basename of the module argument as the module to load, allowing arbitrary modules, even when some kernel subsystems try to prevent this (CVE-2014-9645).
