Summary

A buffer overflow in Smart Card authentication code in gpkcsp.dll in Microsoft Windows XP through SP3 and Server 2003 through SP2 allows a remote attacker to execute arbitrary code on the target computer, provided that the computer is joined in a Windows domain and has Remote Desktop Protocol connectivity (or Terminal Services) enabled.

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.

therefore, affected by one or more of the following vulnerabilities :

  - A remote code execution vulnerability exists in how the

    RDP server has Smart Card authentication enabled. An
    authenticated, remote attacker can exploit this, via a
    specially crafted application, to execute arbitrary code
    with full user privileges. (CVE-2017-0176)

  - A remote code execution vulnerability exists in
    Microsoft Internet Explorer due to improper handling of
    objects in memory. An unauthenticated, remote attacker
    can exploit this, by convincing a user to visit a
    specially crafted website, to execute arbitrary code in
    the context of the current user. (CVE-2017-0222)

  - An information disclosure vulnerability exists in the
    Microsoft Server Message Block 1.0 (SMBv1) server when
    handling certain requests. An unauthenticated, remote
    attacker can exploit this, via a specially crafted
    packet, to disclose sensitive information.
    (CVE-2017-0267)

  - A buffer overflow condition exists in the IIS WebDAV
    service due to improper handling of the 'If' header in a
    PROPFIND request. An unauthenticated, remote attacker
    can exploit this, via a specially crafted request, to
    cause a denial of service condition or the execution of
    arbitrary code. This vulnerability, also known as
    EXPLODINGCAN, is one of multiple Equation Group
    vulnerabilities and exploits disclosed on 2017/04/14 by
    a group known as the Shadow Brokers. (CVE-2017-7269)

  - A remote code execution vulnerability exists in how the

    RDP server has Routing and Remote Access enabled. An
    authenticated, remote attacker can exploit this, via a
    specially crafted application, to execute arbitrary code
    with full user privileges. (CVE-2017-8461)

  - A remote code execution vulnerability exists in Windows
    OLE, specifically in olecnv32.dll, due to improper
    validation of user-supplied input. An unauthenticated,
    remote attacker can exploit this, by convincing a user
    to visit a specially crafted website or to open a
    specially crafted file or email, to execute arbitrary
    code in the context of the current user. (CVE-2017-8487)

  - A remote code execution vulnerability exists in the
    Windows Search functionality due to improper handling of
    objects in memory. An unauthenticated, remote attacker
    can exploit this, via a specially crafted SMB message,
    to execute arbitrary code. (CVE-2017-8543)

  - An information disclosure vulnerability exists in the
    GDI component due to improper handling of objects in
    memory. An unauthenticated, remote attacker can exploit
    this, by convincing a user to open a specially crafted
    document or visit a specially crafted website, to
    disclose the contents of memory. (CVE-2017-8552)");
