Summary
The phpinfo implementation in ext/standard/info.c in PHP before 5.4.30 and 5.5.x before 5.5.14 does not ensure use of the string data type for the PHP_AUTH_PW, PHP_AUTH_TYPE, PHP_AUTH_USER, and PHP_SELF variables, which might allow context-dependent attackers to obtain sensitive information from process memory by using the integer data type with crafted values, related to a "type confusion" vulnerability, as demonstrated by reading a private SSL key in an Apache HTTP Server web-hosting environment with mod_ssl and a PHP 5.3.x mod_php.

implementaci\u00f3n phpinfo en ext/standard/info.c en PHP anterior a 5.4.30 y 5.5.x anterior a 5.5.14 no asegura el uso del tipo de datos de cadenas para las variables PHP_AUTH_PW, PHP_AUTH_TYPE, PHP_AUTH_USER y PHP_SELF, lo que podr\u00eda permitir a atacantes dependientes de contexto obtener informaci\u00f3n sensible de la memoria de proceso mediante el uso de el tipo de datos de enteros con valores manipulados, relacionado con una vulnerabilidad de \u0027confusi\u00f3n de tipo\u0027, tal y como fue demostrado mediante la lectura de una clave SSL privada en un entorno de alojamiento web

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
