Summary
A stack-based buffer overflow vulnerability exists in ActFax Server version 4.32, specifically in the "Import Users from File" functionality of the client interface. The application fails to properly validate the length of tab-delimited fields in .exp files, leading to unsafe usage of strcpy() during CSV parsing. An attacker can exploit this vulnerability by crafting a malicious .exp file and importing it using the default character set "ECMA-94 / Latin 1 (ISO 8859)". Successful exploitation may result in arbitrary code execution, leading to full system compromise. User interaction is required to trigger the vulnerability.

"value": "Existe una vulnerabilidad de desbordamiento de b\u00fafer en la pila de ActFax Server versi\u00f3n 4.32, espec\u00edficamente en la funci\u00f3n \"Importar usuarios desde archivo\" de la interfaz de cliente. La aplicaci\u00f3n no valida correctamente la longitud de los campos delimitados por tabulaciones en archivos .exp, lo que provoca un uso inseguro de strcpy() durante el an\u00e1lisis de CSV. Un atacante puede explotar esta vulnerabilidad manipulando un archivo .exp malicioso e import\u00e1ndolo con el conjunto de caracteres predeterminado \"ECMA-94 / Latin 1 (ISO 8859)\". Una explotaci\u00f3n exitosa puede provocar la ejecuci\u00f3n de c\u00f3digo arbitrario, lo que compromete por completo el sistema. Se requiere la interacci\u00f3n del usuario para activar la vulnerabilidad."
