In the add_match function in libbb/lineedit.c in BusyBox through 1.27.2, the tab autocomplete feature of the shell, used to get a list of filenames in a directory, does not sanitize filenames and results in executing any escape sequence in the terminal. This could potentially result in code execution, arbitrary file writes, or other attacks. En la función add_match en libbb/lineedit.c en BusyBox hasta la versión 1.27.2, la característica de autocompletar pestañas del shell, empleada para obtener una lista de nombres de archivo en un directorio, no inmuniza los nombres de archivo. Esto conduce a la ejecución de cualquier secuencia de escape en el terminal. Esto podría resultar en la ejecución de código, escrituras arbitrarias de archivos u otros ataques. • http://packetstormsecurity.com/files/154361/Cisco-Device-Hardcoded-Credentials-GNU-glibc-BusyBox.html http://packetstormsecurity.com/files/154536/VMware-Security-Advisory-2019-0013.html http://packetstormsecurity.com/files/167552/Nexans-FTTO-GigaSwitch-Outdated-Components-Hardcoded-Backdoor.html http://seclists.org/fulldisclosure/2019/Jun/18 http://seclists.org/fulldisclosure/2019/Sep/7 http://seclists.org/fulldisclosure/2020/Aug/20 http://seclists.org/fulldisclosure/2020/Mar/15 http://seclists.org/fulldisclosure • CWE-94: Improper Control of Generation of Code ('Code Injection') •

Directory traversal vulnerability in the BusyBox implementation of tar before 1.22.0 v5 allows remote attackers to point to files outside the current working directory via a symlink. Una vulnerabilidad de salto de directorio en la implementación de tar en BusyBox en versiones anteriores a 1.22.0 v5 permite que atacantes remotos apunten a archivos situados fuera del actual directorio de trabajo a través de un symlink. 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://packetstormsecurity.com/files/153278/WAGO-852-Industrial-Managed-Switch-Series-Code-Execution-Hardcoded-Credentials.html http://seclists.org/fulldisclosure/2019/Jun/18 http://seclists.org/fulldisclosure/2020/Aug/20 http://www.openwall.com/lists/oss-security/2015/10/21/7 https://bugzilla.redhat.com/show_bug.cgi?id=1274215 https://lists.debian.org/debian-lts-announce/2018/07/msg00037.html https://lists.debian.org/debian-lts-announce/2021/02/msg00020.html https://seclists.org/bugtraq& • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

The recv_and_process_client_pkt function in networking/ntpd.c in busybox allows remote attackers to cause a denial of service (CPU and bandwidth consumption) via a forged NTP packet, which triggers a communication loop. La función recv_and_process_client_pkt en networking/ntpd.c en busybox permite a atacantes remotos provocar una denegación de servicio (consumo de CPU y ancho de banda) a través de un paquete NTP falsificado, lo que desencadena un bucle de comunicación.
