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 version of EMC AutoStart on the remote host reportedly contains multiple remote code execution vulnerabilities : - When creating error messages to be written to logs, a user controlled string from the packet is used as an argument to a function containing a format string. The result of that function is written to a statically-sized buffer on the stack, which can result in a buffer overflow. - ftAgent.exe, when processing messages with opcode 0x11, performs arithmetic on an unvalidated user-supplied value used to determine the size of a new heap buffer. This allows a potential integer wrap to cause a heap- based buffer overflow. - ftAgent.exe, when processing messages with opcode 0x140, performs arithmetic on an unvalidated user-supplied value used to determine the size of a new heap buffer. This allows a potential integer wrap to cause a heap- based buffer overflow. Failed attacks may result in a denial of service. |
