Loading vulnerability…
A use-after-free vulnerability exists in multiple agents of Veritas Backup Exec versions 2014 (prior to build 14.1.1187.1126), 15 (prior to build 14.2.1180.3160), and 16 (prior to FP1). The flaw allows an unauthenticated remote attacker to trigger a use-after-free condition, which can result in a denial of service or potentially allow remote code execution within the context of the agent process.

This repository contains a single Metasploit module (ssl_uaf.rb) that exploits a use-after-free vulnerability (CVE-2017-8895) in the SSL NDMP connection handling of Veritas/Symantec Backup Exec Remote Agent for Windows (versions 14, 15, and 16). The exploit targets the NDMP service, typically running on TCP port 10000, and leverages a race condition in the SSL re-establishment process to achieve remote code execution as SYSTEM. The module supports both 32-bit and 64-bit Windows targets, with specific handling for Windows 8+ and earlier versions due to differences in heap management. The exploit is operational and provides a customizable Metasploit payload, such as a reverse shell. The repository is structured as a standard Metasploit exploit module and is intended for use within the Metasploit Framework.
