Directory Traversal Vulnerability in a UserAdmin Application, SAP security note 2310790

Description

A UserAdmin application allows an attacker to exploit insufficient validation of path information provided by users, thus characters representing ‘traverse to parent directory’ are passed through to the file APIs.

Some well-known impacts of directory traversal vulnerability are the following:

  • An attacker could read content of arbitrary files on the remote server and expose sensitive data.
  • An attacker could overwrite, delete, or corrupt arbitrary files on the remote server.
