CVE-2014-7169 – GNU Bourne-Again Shell (Bash) Arbitrary Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2014-7169
GNU Bash through 4.3 bash43-025 processes trailing strings after certain malformed function definitions in the values of environment variables, which allows remote attackers to write to files or possibly have unknown other impact 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. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-6271. GNU Bash hasta 4.3 bash43-025 procesa cadenas finales después de la definición malformada de funciones en los valores de variables de entorno, lo que permite a atacantes remotos escribir hacia ficheros o posiblemente tener otro impacto desconocido a través de un entorno manipulado, tal y 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 la cual establecer el entorno ocurre a través de un límite privilegiado de la ejecución de Bash. Nota: Esta vulnerabilidad existe debido a una solución incompleta para CVE-2014-6271. It was found that the fix for CVE-2014-6271 was incomplete, and Bash still allowed certain characters to be injected into other environments via specially crafted environment variables. • https://www.exploit-db.com/exploits/34777 https://www.exploit-db.com/exploits/34895 https://www.exploit-db.com/exploits/34839 https://www.exploit-db.com/exploits/36503 https://www.exploit-db.com/exploits/36504 https://www.exploit-db.com/exploits/34766 https://www.exploit-db.com/exploits/35115 https://www.exploit-db.com/exploits/36933 https://www.exploit-db.com/exploits/34765 https://www.exploit-db.com/exploits/34860 https://www.exploit-db.com/exploits/34879 • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') CWE-228: Improper Handling of Syntactically Invalid Structure •
CVE-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') •

CVE-2012-1493 – F5 BIG-IP - Authentication Bypass (PoC)
https://notcve.org/view.php?id=CVE-2012-1493
F5 BIG-IP appliances 9.x before 9.4.8-HF5, 10.x before 10.2.4, 11.0.x before 11.0.0-HF2, and 11.1.x before 11.1.0-HF3, and Enterprise Manager before 2.1.0-HF2, 2.2.x before 2.2.0-HF1, and 2.3.x before 2.3.0-HF3, use a single SSH private key across different customers' installations and do not properly restrict access to this key, which makes it easier for remote attackers to perform SSH logins via the PubkeyAuthentication option. El dispositivo F5 BIG-IP v9.x anteriores a v9.4.8-HF5, v10.x anteriores a v10.2.4, v11.0.x anteriores a v11.0.0-HF2, y v11.1.x anteriores a v11.1.0-HF3, y Enterprise Manager anteriores a v2.1.0-HF2, v2.2.x anteriores a v2.2.0-HF1, y v2.3.x anteriores a v2.3.0-HF3, usa una clave privada SSH en distintas instalaciones de clientes, y no restringe el acceso a la mismas de forma adecuada, lo que facilita a atacantes remotos hacer login SSH a través de la opción PubkeyAuthentication. F5 ships a public/private key pair on BIG-IP appliances that allows passwordless authentication to any other BIG-IP box. Since the key is easily retrievable, an attacker can use it to gain unauthorized remote access as root. • https://www.exploit-db.com/exploits/19064 https://www.exploit-db.com/exploits/19091 https://www.exploit-db.com/exploits/19099 http://support.f5.com/kb/en-us/solutions/public/13000/600/sol13600.html http://www.theregister.co.uk/2012/06/13/f5_kit_metasploit_exploit https://github.com/rapid7/metasploit-framework/blob/master/modules/exploits/linux/ssh/f5_bigip_known_privkey.rb https://www.trustmatta.com/advisories/MATTA-2012-002.txt • CWE-255: Credentials Management Errors •
CVE-2011-3188 – kernel: net: improve sequence number generation
https://notcve.org/view.php?id=CVE-2011-3188
The (1) IPv4 and (2) IPv6 implementations in the Linux kernel before 3.1 use a modified MD4 algorithm to generate sequence numbers and Fragment Identification values, which makes it easier for remote attackers to cause a denial of service (disrupted networking) or hijack network sessions by predicting these values and sending crafted packets. Las implementaciones de (1) IPv4 y (2) IPv6 en el kernel de Linux antes de v3.1 utiliza una versión modificada de algoritmo MD4 para generar números de secuencia y valores de los fragmentos de identificación, lo que hace que sea más fácil para los atacantes remotos causar una denegación de servicio (red interrumpida) o secuestrar sesiones de red mediante la predicción de estos valores y el envío de paquetes manipulados. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=6e5714eaf77d79ae1c8b47e3e040ff5411b717ec http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=bc0b96b54a21246e377122d54569eef71cec535f http://marc.info/?l=bugtraq&m=139447903326211&w=2 http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.1 http://www.openwall.com/lists/oss-security/2011/08/23/2 https://bugzilla.redhat.com/show_bug.cgi?id=732658 https://github.com/torval •
