Descriptions
Eaton HMiSoft VU3 (HMIVU3 runtime not impacted), Version 3.00.23 and prior, however, the HMIVU runtimes are not impacted by these issues. A specially crafted input file could cause a buffer overflow when loaded by the affected product.
Eaton HMiSoft VU3 (el tiempo de ejecución de HMIVU3 no está impactado), versiones 3.00.23 y anteriores, sin embargo, los tiempos de ejecución de HMIVU no están impactados por estos problemas. Un archivo de entrada especialmente diseñado podría causar un desbordamiento del búfer cuando es cargado por parte del producto afectado.
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Eaton HMiSoft. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the parsing of VU3 files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.
