MSRPC vulnerabilities

Improper access control in Windows RPC API allows an authorized attacker to elevate privileges locally.

Improper privilege management in Windows Remote Desktop allows an authorized attacker to elevate privileges locally.

External control of file name or path in Windows Telephony Service allows an authorized attacker to elevate privileges over an adjacent network.

Exposure of sensitive information to an unauthorized actor in Windows Remote Procedure Call allows an unauthorized attacker to disclose information locally.

Exposure of sensitive information to an unauthorized actor in Desktop Windows Manager allows an authorized attacker to disclose information locally.

External control of file name or path in Windows Storage allows an authorized attacker to perform spoofing over a network.

Time-of-check time-of-use (toctou) race condition in Windows Fundamentals allows an authorized attacker to execute code over a network.

Use after free in RPC Endpoint Mapper Service allows an authorized attacker to elevate privileges locally.

Exposed dangerous method or function in Windows Local Session Manager (LSM) allows an authorized attacker to deny service over a network.

vCenter Server contains a heap-overflow vulnerability in the implementation of the DCERPC protocol. A malicious actor with network access to vCenter Server may trigger this vulnerability by sending a specially crafted network packet potentially leading to remote code execution.

A vulnerability was found in Samba's "rpcecho" development server, a non-Windows RPC server used to test Samba's DCE/RPC stack elements. This vulnerability stems from an RPC function that can be blocked indefinitely. The issue arises because the "rpcecho" service operates with only one worker in the main RPC task, allowing calls to the "rpcecho" server to be blocked for a specified time, causing service disruptions. This disruption is triggered by a "sleep()" call in the "dcesrv_echo_TestSleep()" function under specific conditions. Authenticated users or attackers can exploit this vulnerability to make calls to the "rpcecho" server, requesting it to block for a specified duration, effectively disrupting most services and leading to a complete denial of service on the AD DC. The DoS affects all other services as "rpcecho" runs in the main RPC task.

Windows Print Spooler Remote Code Execution Vulnerability

Windows Print Spooler Spoofing Vulnerability

An information disclosure vulnerability exists in RPC if the server has Routing and Remote Access enabled. An attacker who successfully exploited this vulnerability could obtain information to further compromise the user’s system To exploit this vulnerability, an attacker would need to run a specially crafted application against an RPC server which has Routing and Remote Access enabled. Routing and Remote Access is a non-default configuration; systems without it enabled are not vulnerable. The security update addresses the vulnerability by correcting how the Routing and Remote Access service handles requests.
