COMPLETE Summary
Multiple stack-based buffer overflows in the BackupToAvi method in the (1) UMS_Ctrl 1.5.1.1 and (2) UMS_Ctrl_STW 2.0.1.0 ActiveX controls in Samsung NET-i viewer 1.37.120316 allow remote attackers to execute arbitrary code via a long string in the fname parameter. NOTE: some of these details are obtained from third party information.

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 in the CNC_Ctrl.dll ActiveX control installed with the Samsung NET-i viewer 1.37. Specifically, when supplying a long string for the fname parameter to the BackupToAvi method, an integer overflow occurs, which leads to a posterior buffer overflow due to the use of memcpy with an incorrect size, resulting in remote code execution under the context of the user. |
