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-2014-3573 – Engine: XML eXternal Entity (XXE) flaw in backend module
https://notcve.org/view.php?id=CVE-2014-3573
The oVirt Engine backend module, as used in Red Hat Enterprise Virtualization Manager before 3.4.2, uses an "insecure DocumentBuilderFactory," which allows remote attackers to read arbitrary files or possibly have other unspecified impact via a crafted XML/RSDL document, related to an XML External Entity (XXE) issue. El módulo de backend oVirt Engine, como el utilizado en Red Hat Enterprise Virtualization Manager anterior a 3.4.2, utiliza una 'DocumentBuilderFactory insegura', lo que permite a atacantes remotos leer archivos arbitrarios o, posiblemente, tener otro impacto sin especificar a través de un documento XML/RSDL manipulado, relacionado con un problema de tipo XML External Entity (XXE). It was discovered that, when loading XML/RSDL documents, the oVirt Engine back end module used an insecure DocumentBuilderFactory. A remote, authenticated attacker could use this flaw to read files accessible to the user running the ovirt-engine server, and potentially perform other more advanced XML External Entity (XXE) attacks. • http://rhn.redhat.com/errata/RHSA-2014-1161.html http://www.securitytracker.com/id/1030807 https://access.redhat.com/security/cve/CVE-2014-3573 https://bugzilla.redhat.com/show_bug.cgi?id=1125795 • CWE-20: Improper Input Validation CWE-611: Improper Restriction of XML External Entity Reference •
