NONE Summary
Microsoft XML Core Services (MSXML) in Windows 10 Gold, 1511, and 1607; Windows 7 SP1; Windows 8.1; Windows RT 8.1; Windows Server 2008 SP2 and R2 SP1; Windows Server 2012 Gold and R2; Windows Server 2016; and Windows Vista SP2 improperly handles objects in memory, allowing attackers to test for files on disk via a crafted web site, aka "Microsoft XML Information Disclosure Vulnerability."
Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Buffer Overflow via Environment Variables This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
- Overflow Buffers Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
- Client-side Injection-induced Buffer Overflow This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
- Filter Failure through Buffer Overflow In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
- MIME Conversion An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

| description | The remote Windows host is affected by an information disclosure vulnerability in Microsoft XML Core Services (MSXML) due to improper handling of objects in memory. An unauthenticated, remote attacker can exploit this vulnerability, by convincing a user to visit a specially crafted website, to test for the presence of files on disk. |
