Vulnerabilities > CVE-2017-0103 - Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in Microsoft products
Attack vector
LOCAL Attack complexity
HIGH Privileges required
LOW Confidentiality impact
HIGH Integrity impact
HIGH Availability impact
HIGH Summary
The kernel API in Microsoft Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, and Windows Server 2012 mishandles registry objects in memory, which allows local users to gain privileges via a crafted application, aka "Windows Registry Elevation of Privilege Vulnerability."

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 missing a security update. It is, therefore, affected by multiple elevation of privilege vulnerabilities : - An elevation of privilege vulnerability exists in the Windows Kernel API due to improper enforcement of permissions. A local attacker can exploit this, via a specially crafted application, to run processes in an elevated context. (CVE-2017-0050) - An elevation of privilege vulnerability exists in the Windows Transaction Manager due to improper handling of objects in memory. A local attacker can exploit this, via a specially crafted application, to run processes in an elevated context. (CVE-2017-0101) - An elevation of privilege vulnerability exists due to a failure to check the length of a buffer prior to copying memory. A local attacker can exploit this, by copying a file to a shared folder or drive, to gain elevated privileges. (CVE-2017-0102) - An elevation of privilege vulnerability exists in the Windows Kernel API due to improper handling of objects in memory. A local attacker can exploit this, via a specially crafted application, to gain elevated privileges. (CVE-2017-0103) |
