Untrusted search path vulnerability in the installation functionality in Ruby 1.9.3-p194, when installed in the top-level C:\ directory, might allow local users to gain privileges via a Trojan horse DLL in the C:\Ruby193\bin directory, which may be added to the PATH system environment variable by an administrator, as demonstrated by a Trojan horse wlbsctrl.dll file used by the "IKE and AuthIP IPsec Keying Modules" system service in Windows Vista SP1, Windows Server 2008 SP2, Windows 7 SP1, and Windows 8 Release Preview. NOTE: CVE disputes this issue because the unsafe PATH is established only by a separate administrative action that is not a default part of the Ruby installation ** DISPUTADA** Vulnerabilidad de path de búsqueda no confiable en la funcionalidad de instalación de Ruby 1.9.3-p194, cuando está instalada en el directorio C:\, podría permitir a usuarios locales obetner privilegios a través de un fichero DLL troyanizado en el directorio "C:\Ruby193\bin", el cual puede ser añadido a la variable de entorno PATH por un adminsitrador, como se demostró con el fichero wlbsctrl.dll troyanizado usado en el servicio de sistema "IKE and AuthIP IPsec Keying Modules" en Windows Vista SP1, Windows Server 2008 SP2, Windows 7 SP1, y Windows 8 Release Preview. NOTA: CVE disputa esta vulnerabilidad debida a un problema con PATH, que es un problema administrativo, y no es una parte por defecto de la instalación de Ruby. • https://www.exploit-db.com/exploits/28130 https://www.htbridge.com/advisory/HTB23108 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
