Atlas SQL JDBC Driver URI Redirection Vulnerability

Sources read

1

Source agreement

Tam uyum

Evidence confidence

%55

Short explanation

A URI redirection weakness exists in the authentication component of the Atlas SQL JDBC Driver (S0). During an interactive sign-in flow, the driver accepts endpoint addresses supplied by remote endpoints without scheme validation and passes them to the local default protocol handler (S0). An unauthenticated remote party may cause an address of its choosing to be opened on the user's system (S0).

Why does it matter?

This vulnerability allows attackers to leverage user interaction to open arbitrary addresses via the local operating system protocol handler, resulting in a low impact on integrity (S0).

What should be done?

  • Follow official vendor advisories (S0)
  • Review MongoDB changelogs and tracker entries (S0)

Show the technical text from the sources

A URI redirection weakness exists in the authentication component of the Atlas SQL JDBC Driver. During an interactive sign-in flow the driver accepts endpoint addresses supplied by the remote endpoint it is pointed at without validating their scheme, and passes the resulting address to the local default protocol handler. An unauthenticated remote party that controls the endpoint a user elects to connect to may cause an address of its choosing to be opened on the user's system; user interaction is required.
