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 : - The EMC AutoStart ftAgent, when processing messages with opcode 0x32 and subcode 0x04, opcode 0x32 and subcode 0x02, opcode 0x03 and subcode 0x04, opcode 0x55 and subcode 0x16, opcode 0x55 and subcode 0x01, opcode 0x41 and subcode 0x12, opcode 0x32 and subcode 0x3C, opcode 0x32 and subcode 0x2A, 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. (ZDI-12-116, ZDI-12-117, ZDI-12-118, ZDI-12-120, ZDI-12-121, ZDI-12-122, ZDI-12-123, ZDI-12-124, respectively) - The EMC AutoStart ftAgent, when processing messages with opcode 0x41 and subcode 0x00, uses an uninitialized stack variable in calculating a memory pointer. Also, the function uses signed extension and signed comparison when checking the uninitialized stack variable, which allows arbitrary negative values to bypass the check. This could result in corruption of a controlled memory location, which can be leveraged to execute code under the context of a privileged user. (ZDI-12-119) Failed attacks may result in a denial of service. |
