Official description

IBM TXSeries for Multiplatforms 9.1 and 11.1 could disclose sensitive information to a remote attacker due to improper neutralization of HTTP headers.

Source: the CVE record as published by its numbering authority, via NVD and CVE.org.

The underlying weakness: Improper Neutralization of HTTP Headers for Scripting Syntax

The product does not neutralize or incorrectly neutralizes web scripting syntax in HTTP headers that can be used by web browser components that can process raw headers, such as Flash.

How developers prevent this class of flaw

  • Carefully control data that is being placed both in HTTP response headers and in the HTTP response body to ensure that no scripting syntax is present, taking various encodings into account. Perform output validation in order to filter/escape/encode unsafe data that is being passed from the server in an HTTP response header.
  • Disable script execution functionality in the clients' browser.
