Vulnerability from fkie_nvd - Published: 2025-08-27 22:15 - Updated: 2026-09-26 00:10
Severity
Summary
A heap-based buffer overflow vulnerability exists in the input parsing logic of Arcserve Unified Data Protection (UDP). This flaw can be triggered without authentication by sending specially crafted input to the target system. Improper bounds checking allows an attacker to overwrite heap memory, potentially leading to application crashes or remote code execution. Exploitation occurs in the context of the affected process and does not require user interaction. The vulnerability poses a high risk due to its pre-authentication nature and potential for full compromise. This vulnerability affects all UDP versions prior to 10.2. UDP 10.2 includes the necessary patches and requires no action. Versions 8.0 through 10.1 are supported and require either patch application or upgrade to 10.2. Versions 7.x and earlier are unsupported or out of maintenance and must be upgraded to 10.2 to remediate the issue.

"value": "Una vulnerabilidad de desbordamiento de b\u00fafer basado en heap-based existe en la l\u00f3gica de an\u00e1lisis de entrada de Arcserve Unified Data Protection (UDP). Este fallo puede ser activado sin autenticaci\u00f3n enviando una entrada especialmente dise\u00f1ada al sistema objetivo. La comprobaci\u00f3n de l\u00edmites incorrecta permite a un atacante sobrescribir la memoria heap, lo que podr\u00eda llevar a fallos de la aplicaci\u00f3n o a la ejecuci\u00f3n remota de c\u00f3digo. La explotaci\u00f3n ocurre en el contexto del proceso afectado y no requiere interacci\u00f3n del usuario. La vulnerabilidad plantea un alto riesgo debido a su naturaleza de pre-autenticaci\u00f3n y su potencial de compromiso total. Esta vulnerabilidad afecta a todas las versiones de UDP anteriores a la 10.2. UDP 10.2 incluye los parches necesarios y no requiere ninguna acci\u00f3n. Las versiones 8.0 a 10.1 son compatibles y requieren la aplicaci\u00f3n de parches o la actualizaci\u00f3n a la 10.2. Las versiones 7.x y anteriores no son compatibles o est\u00e1n fuera de mantenimiento y deben actualizarse a la 10.2 para remediar el problema."
