COMPLETE Summary
Multiple buffer overflows in the ISSymbol ActiveX control in ISSymbol.ocx 61.6.0.0 and 301.1009.2904.0 in the ISSymbol virtual machine, as distributed in Advantech Studio 6.1 SP6 61.6.01.05, InduSoft Web Studio before 7.0+SP1, and InduSoft Thin Client 7.0, allow remote attackers to execute arbitrary code via a long (1) InternationalOrder, (2) InternationalSeparator, or (3) LogFileName property value; or (4) a long bstrFileName argument to the OpenScreen method.

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 | This module exploits a heap overflow found in InduSoft Web Studio <= 61.6.00.00 SP6. The overflow exists in the ISSymbol.ocx, and can be triggered with a long string argument for the InternationalSeparator() method of the ISSymbol control. This module uses the msvcr71.dll form the Java JRE6 to bypass ASLR. |
