Descriptions

Smarty_Security::isTrustedResourceDir() in Smarty before 3.1.33 is prone to a path traversal vulnerability due to insufficient template code sanitization. This allows attackers controlling the executed template code to bypass the trusted directory security restriction and read arbitrary files.

Smarty_Security::isTrustedResourceDir() en Smarty en versiones anteriores a la 3.1.33 es propenso a una vulnerabilidad de salto de directorio debido al saneamiento insuficiente de códigos de plantilla. Esto permite que los atacantes que controlan el código de plantilla ejecutado omitan las restricciones de seguridad del directorio de confianza y lean archivos arbitrarios.

David Gnedt and Thomas Konrad discovered that Smarty was incorrectly sanitizing the paths present in the templates. An attacker could possibly use this use to read arbitrary files when controlling the executed template. It was discovered that Smarty was incorrectly sanitizing the paths present in the templates.
