Summary

vbscript.dll in Microsoft VBScript 5.6 through 5.8, as used with Internet Explorer 6 through 11 and other products, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted web site, aka "VBScript Memory Corruption 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.

    descriptionThe version of Internet Explorer installed on the remote host is missing Cumulative Security Update 3076321. It is, therefore, affected by multiple vulnerabilities, the majority of which are remote code execution vulnerabilities. An attacker can exploit these vulnerabilities by convincing a user to visit a specially crafted website. Hosts running Internet Explorer 10 or Internet Explorer 11 will not be fully protected until both security update 3065822 and security update 3075516 are applied to the system. Security update 3075516 may require manual installation depending on your patching method. Note that the majority of the vulnerabilities addressed by Cumulative Security Update 3076321 are mitigated by the Enhanced Security Configuration (ESC) mode which is enabled by default on Windows Server 2003, 2008, 2008 R2, 2012, and 2012 R2.
