Description

Description

In Spring Framework, versions 6.0.x as of 6.0.5, versions 6.1.x and 6.2.x, an application is vulnerable to a reflected file download (RFD) attack when it sets a “Content-Disposition” header with a non-ASCII charset, where the filename attribute is derived from user-supplied input.

Specifically, an application is vulnerable when all the following are true:

  • The header is prepared with org.springframework.http.ContentDisposition.
  • The filename is set via ContentDisposition.Builder#filename(String, Charset).
  • The value for the filename is derived from user-supplied input.
  • The application does not sanitize the user-supplied input.
  • The downloaded content of the response is injected with malicious commands by the attacker (see RFD paper reference for details).

An application is not vulnerable if any of the following is true:

  • The application does not set a “Content-Disposition” response header.
  • The header is not prepared with org.springframework.http.ContentDisposition.
  • The filename is set via one of:
    • ContentDisposition.Builder#filename(String), or
    • ContentDisposition.Builder#filename(String, ASCII)
  • The filename is not derived from user-supplied input.
  • The filename is derived from user-supplied input but sanitized by the application.
  • The attacker cannot inject malicious content in the downloaded content of the response.

Affected Spring Products and VersionsSpring Framework

  • 6.2.0 - 6.2.7
  • 6.1.0 - 6.1.20
  • 6.0.5 - 6.0.28
  • Older, unsupported versions are not affected

Mitigation

Users of affected versions should upgrade to the corresponding fixed version.

The vulnerability can be exploited over the network without needing physical access. It is difficult for an attacker to exploit this vulnerability and may require special conditions. An attacker needs basic access or low-level privileges. The attacker needs the user to perform some action, like clicking a link. The vulnerability can affect other systems as well, not just the initial system. There is a high impact on the confidentiality of the information. There is a low impact on the integrity of the data.
