"value": "A medium severity vulnerability has been identified in the update mechanism of the Phish Alert Button for Outlook, which could allow an attacker to remotely execute arbitrary code on the host machine. The vulnerability arises from the application's failure to securely verify the authenticity and integrity of the update server.\n\nThe application periodically checks for updates by querying a specific URL. However, this process does not enforce strict SSL/TLS verification, nor does it validate the digital signature of the received update files. An attacker with the capability to perform DNS spoofing can exploit this weakness. By manipulating DNS responses, the attacker can redirect the application's update requests to a malicious server under their control.\n\nOnce the application queries the spoofed update URL, the malicious server can respond with a crafted update package. Since the application fails to properly verify the authenticity of the update file, it will accept and execute the package, leading to arbitrary code execution on the host machine.\n\nImpact:\nSuccessful exploitation of this vulnerability allows an attacker to execute code with elevated privileges, potentially leading to data theft, installation of further malware, or other malicious activities on the host system.\n\nAffected Products:\nPhish Alert Button (PAB) for Outlook versions 1.10.0-1.10.11\nSecond Chance Client versions 2.0.0-2.0.9\nPIQ Client versions 1.0.0-1.0.15\n\nRemediation:\nAutomated updates will be pushed to address this issue. Users of affected versions should verify the latest version is applied and, if not, apply the latest updates provided by KnowBe4, which addresses this vulnerability by implementing proper SSL/TLS checks of the update server. It is also recommended to ensure DNS settings are secure to prevent DNS spoofing attacks.\n\nWorkarounds:\nUse secure corporate networks or VPN services to secure network communications, which can help mitigate the risk of DNS spoofing.\n\nCredits:\nThis vulnerability was discovered by Ceri Coburn at Pen Test Partners, who reported it responsibly to the vendor."

"value": "Se ha identificado una vulnerabilidad de gravedad media en el mecanismo de actualizaci\u00f3n del bot\u00f3n de alerta de phishing para Outlook, que podr\u00eda permitir a un atacante ejecutar de forma remota c\u00f3digo arbitrario en la m\u00e1quina host. La vulnerabilidad surge de la falla de la aplicaci\u00f3n al verificar de forma segura la autenticidad y la integridad del servidor de actualizaci\u00f3n. La aplicaci\u00f3n busca peri\u00f3dicamente actualizaciones consultando una URL espec\u00edfica. Sin embargo, este proceso no exige una verificaci\u00f3n SSL/TLS estricta ni valida la firma digital de los archivos de actualizaci\u00f3n recibidos. Un atacante con la capacidad de realizar suplantaci\u00f3n de DNS puede aprovechar esta debilidad. Al manipular las respuestas de DNS, el atacante puede redirigir las solicitudes de actualizaci\u00f3n de la aplicaci\u00f3n a un servidor malicioso bajo su control. Una vez que la aplicaci\u00f3n consulta la URL de actualizaci\u00f3n falsificada, el servidor malicioso puede responder con un paquete de actualizaci\u00f3n manipulado. Dado que la aplicaci\u00f3n no puede verificar adecuadamente la autenticidad del archivo de actualizaci\u00f3n, aceptar\u00e1 y ejecutar\u00e1 el paquete, lo que provocar\u00e1 la ejecuci\u00f3n de c\u00f3digo arbitrario en la m\u00e1quina host. Impacto: la explotaci\u00f3n exitosa de esta vulnerabilidad permite a un atacante ejecutar c\u00f3digo con privilegios elevados, lo que podr\u00eda provocar el robo de datos, la instalaci\u00f3n de m\u00e1s malware u otras actividades maliciosas en el sistema host. Productos afectados: Bot\u00f3n de alerta de phishing (PAB) para las versiones de Outlook 1.10.0-1.10.11 Versiones del cliente de segunda oportunidad 2.0.0-2.0.9 Versiones del cliente PIQ 1.0.0-1.0.15 Soluci\u00f3n: se enviar\u00e1n actualizaciones autom\u00e1ticas para solucionar este problema asunto. Los usuarios de las versiones afectadas deben verificar que se haya aplicado la \u00faltima versi\u00f3n y, de lo contrario, aplicar las \u00faltimas actualizaciones proporcionadas por KnowBe4, que aborda esta vulnerabilidad implementando comprobaciones SSL/TLS adecuadas del servidor de actualizaciones. Tambi\u00e9n se recomienda garantizar que la configuraci\u00f3n de DNS sea segura para evitar ataques de suplantaci\u00f3n de DNS. Workarounds: utilice redes corporativas seguras o servicios VPN para proteger las comunicaciones de red, lo que puede ayudar a mitigar el riesgo de suplantaci\u00f3n de DNS. Cr\u00e9ditos: esta vulnerabilidad fue descubierta por Ceri Coburn de Pen Test Partners, quien la inform\u00f3 responsablemente al proveedor."
