Descriptions

In Apache httpd 2.2.0 to 2.4.29, when generating an HTTP Digest authentication challenge, the nonce sent to prevent reply attacks was not correctly generated using a pseudo-random seed. In a cluster of servers using a common Digest authentication configuration, HTTP requests could be replayed across servers by an attacker without detection.

En Apache httpd, en versiones desde la 2.2.0 hasta la 2.4.29, cuando se genera un desafío de autenticación HTTP Digest, el nonce enviado para evitar ataques replay no se generó correctamente empleando una semilla pseudoaleatoria. En un clúster de servidores, utilizando una configuración de autenticación Digest común, las peticiones HTTP se podrían reemplazar en los servidores por un atacante si que este sea detectado.
