Descriptions

Dell EMC Open Manage System Administrator (OMSA) versions prior to 9.3.0 contain an Improper Range Header Processing Vulnerability. A remote unauthenticated attacker may send crafted requests with overlapping ranges to cause the application to compress each of the requested bytes, resulting in a crash due to excessive memory consumption and preventing users from accessing the system.

Las versiones de Dell EMC Open Manage System Administrator (OMSA) anteriores a la 9.3.0 contienen una vulnerabilidad de procesamiento de encabezado de rango inadecuado. Un atacante remoto no autenticado puede enviar peticiones especialmente modificadas con rangos de solapamiento para hacer que la aplicación comprima cada uno de los bytes solicitados, lo que resulta en un fallo debido al consumo excesivo de memoria e impide que los usuarios accedan al sistema.

*Credits: Dell EMC would like to thank Murat Aydemir of Biznet Billisim A.S. for reporting this issue.
