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. La función add_probe en modutils/modprobe.c en BusyBox en versiones anteriores a 1.23.0 permite a usuarios locales eludir las restricciones previstas al cargar los módulos del kernel a través de un caracter / (barra oblicua) en un nombre de módulo, tal como lo demuestra un comando "ifconfig /usbserial up" o un comando "mount -t /snd_pcm none /". • http://git.busybox.net/busybox/commit/?id=4e314faa0aecb66717418e9a47a4451aec59262b http://openwall.com/lists/oss-security/2015/01/24/4 http://seclists.org/fulldisclosure/2020/Mar/15 http://www.securityfocus.com/bid/72324 https://bugs.busybox.net/show_bug.cgi?id=7652 https://bugzilla.redhat.com/show_bug.cgi?id=1185707 https://lists.debian.org/debian-lts-announce/2018/07/msg00037.html https://plus.google.com/+MathiasKrause/posts/PqFCo4bfrWu https://security.gentoo.org/glsa/201503-1 • CWE-20: Improper Input Validation •

util-linux/mdev.c in BusyBox before 1.21.0 uses 0777 permissions for parent directories when creating nested directories under /dev/, which allows local users to have unknown impact and attack vectors. util-linux/mdev.c en BusyBox anterior a la versión 1.21.0 utiliza permisos 0777 en directorios padre al crear directorios anidados bajo /dev/, lo que permite a usuarios locales tener un impacto y vectores de ataques desconocidos. The industrial managed switch series 852 from WAGO is affected by multiple vulnerabilities such as old software components embedded in the firmware. Furthermore, hardcoded password hashes and credentials were also found by doing an automated scan with IoT Inspector. • http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=701965 http://git.busybox.net/busybox/commit/?id=4609f477c7e043a4f6147dfe6e86b775da2ef784 http://lists.busybox.net/pipermail/busybox/2013-January/078864.html http://packetstormsecurity.com/files/153278/WAGO-852-Industrial-Managed-Switch-Series-Code-Execution-Hardcoded-Credentials.html http://rhn.redhat.com/errata/RHSA-2013-1732.html http://seclists.org/fulldisclosure/2019/Jun/18 http://seclists.org/fulldisclosure/2020/Aug/20 http://seclists.org/fulldisclosure& • CWE-264: Permissions, Privileges, and Access Controls •
