Vulnerability from fkie_nvd - Published: 2024-12-19 10:15 - Updated: 2025-06-09 17:15
Severity ?
5.6 (Medium) - CVSS:4.0/AV:L/AC:H/AT:P/PR:H/UI:N/VC:N/VI:N/VA:H/SC:N/SI:L/SA:N
Summary
Netskope was made aware of a security vulnerability in Netskope Endpoint DLP’s Content Control Driver where a double-fetch issue leads to heap overflow. The vulnerability arises from the fact that the NumberOfBytes argument to ExAllocatePoolWithTag, and the Length argument for RtlCopyMemory, both independently dereference their value from the user supplied input buffer inside the EpdlpSetUsbAction function, known as a double-fetch. If this length value grows to a higher value in between these two calls, it will result in the RtlCopyMemory call copying user-supplied memory contents outside the range of the allocated buffer, resulting in a heap overflow. A malicious attacker will need admin privileges to exploit the issue. This issue affects Endpoint DLP version below R119.

La vulnerabilidad surge del hecho de que el argumento NumberOfBytes de ExAllocatePoolWithTag y el argumento Length de RtlCopyMemory desreferencian de forma independiente su valor del b\u00fafer de entrada proporcionado por el usuario dentro de la funci\u00f3n EpdlpSetUsbAction, lo que se conoce como doble b\u00fasqueda. Si este valor de longitud aumenta hasta un valor mayor entre estas dos llamadas, la llamada RtlCopyMemory copiar\u00e1 el contenido de la memoria proporcionada por el usuario fuera del rango del b\u00fafer asignado, lo que provocar\u00e1 un desbordamiento del mont\u00f3n. Un atacante malintencionado necesitar\u00e1 privilegios de administrador para explotar el problema. Este problema afecta a la versi\u00f3n de Endpoint DLP anterior a R119."
