This vulnerability affects a backup and data protection management application. While these systems are typically deployed within internal administrative zones and are not intended to be exposed to the public internet, they are web-based management interfaces that could be exposed in some deployments, though such exposure is not a standard or recommended practice for this product category.

Horizon Alert

Summary of the vulnerability and why it matters

A directory traversal vulnerability exists in Arcserve UDP. This flaw allows attackers to access or manipulate files on the system. The primary business impact could be the exposure of sensitive information or disruption of data protection services.

  • Vulnerable Arcserve UDP components
  • Improper handling of file paths
  • Sensitive data exposure or service disruption

Attack Path

How an attacker could exploit the issue

This vulnerability allows remote attackers to access or disrupt Arcserve UDP services through a directory traversal flaw. Attackers can exploit this by sending specially crafted file paths to specific servlets within the application. This could lead to unauthorized disclosure of sensitive information or cause the application to become unavailable to legitimate users.

  • Exposure via network.
  • Attacker sends crafted path.
  • Sensitive data exposed or service denied.

Live Threat

Current exploitation, exposure, and threat context
