CVSS: 10.0EPSS: 97%CPEs: 345EXPL: 54CVE-2014-6271 – GNU Bourne-Again Shell (Bash) Arbitrary Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2014-6271
GNU Bash through 4.3 processes trailing strings after function definitions in the values of environment variables, which allows remote attackers to execute arbitrary code via a crafted environment, as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the mod_cgi and mod_cgid modules in the Apache HTTP Server, scripts executed by unspecified DHCP clients, and other situations in which setting the environment occurs across a privilege boundary from Bash execution, aka "ShellShock." NOTE: the original fix for this issue was incorrect; CVE-2014-7169 has been assigned to cover the vulnerability that is still present after the incorrect fix. GNU Bash hasta la versión 4.3 procesa cadenas finales después de las definiciones de funciones en los valores de variables de entorno, lo que permite a atacantes remotos ejecutar código arbitrario a través de un entorno manipulado, tal como se ha demostrado por vectores que involucran la característica ForceCommand en sshd OpenSSH, los módulos mod_cgi y mod_cgid en el Apache HTTP Server, scripts ejecutados por clientes DHCP no especificados, y otras situaciones en las cuales el ajuste de entorno ocurre a través de un límite privilegiado de la ejecución de Bash, también conocido como "ShellShock." NOTA: la reparación original para este problema era incorrecta; CVE-2014-7169 ha sido asignada para cubrir la vulnerabilidad que todavía está presente después de la solución incorrecta. A flaw was found in the way Bash evaluated certain specially crafted environment variables. • https://github.com/darrenmartyn/visualdoor https://www.exploit-db.com/exploits/38849 https://www.exploit-db.com/exploits/34777 https://www.exploit-db.com/exploits/39918 https://www.exploit-db.com/exploits/34895 https://www.exploit-db.com/exploits/34839 https://www.exploit-db.com/exploits/40619 https://www.exploit-db.com/exploits/36503 https://www.exploit-db.com/exploits/36504 https://www.exploit-db.com/exploits/40938 https://www.exploit-db.com/exploits/34900 https • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') CWE-94: Improper Control of Generation of Code ('Code Injection') •

Stack-based buffer overflow in lib/sh/eaccess.c in GNU Bash before 4.2 patch 33 might allow local users to bypass intended restricted shell access via a long filename in /dev/fd, which is not properly handled when expanding the /dev/fd prefix. Desbordamiento de búfer basado en pila en lib/sh/eaccess.c en GNU Bash anterior a v4.2 parche 33 podría permitir a usuarios locales eludir acceso intención shell restringido a través de un nombre de archivo largo en /dev/fd, que no se utilizan con cuidado cuando se expande el directorio /dev/fd. • ftp://ftp.gnu.org/pub/gnu/bash/bash-4.2-patches/bash42-033 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=681278 http://secunia.com/advisories/51086 http://security.gentoo.org/glsa/glsa-201210-05.xml http://www.mandriva.com/security/advisories?name=MDVSA-2012:128 http://www.openwall.com/lists/oss-security/2012/07/11/11 http://www.openwall.com/lists/oss-security/2012/07/11/22 http://www.openwall.com/lists/oss-security/2012/07/12/4 http://www.secu • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
