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.

Metasploit
description | This module exploits a vulnerability found in TFTP Server 1.4 ST. The flaw is due to the way TFTP handles the filename parameter extracted from a WRQ request. The server will append the user-supplied filename to TFTP server binary's path without any bounds checking, and then attempt to check this path with a fopen(). Since this isn't a valid file path, fopen() returns null, which allows the corrupted data to be used in a strcmp() function, causing an access violation. Since the offset is sensitive to how the TFTP server is launched, you must know in advance if your victim machine launched the TFTP as a 'Service' or 'Standalone' , and then manually select your target accordingly. A successful attempt will lead to remote code execution under the context of SYSTEM if run as a service, or the user if run as a standalone. A failed attempt will result a denial-of-service. |
