Description

API Platform Core can leak exceptions message that may contain sensitive information

Summary

Exception messages, that are not HTTP exceptions, are visible in the JSON error response.

Details

While we wanted to make our errors compatible with the [JSON Problem](https://datatracker.ietf.org/doc/html/rfc7807) specification, we ended up handling more exceptions then we did previously (introduced at https://github.com/api-platform/core/pull/5823). Instead of leaving that to Symfony, we ended up serializing errors with our normalizers which lead to not hiding the exception details. Note that the trace is hidden in production but the message is not, and the message can contain sensitive information.

PoC

At https://github.com/ili101/api-platform/tree/test3.2 it triggers an authentication exception as LDAP is not reachable. You can find the message available as a JSON response when trying to reach an endpoint.

Impact

Version 3.2 until 3.2.4 is impacted.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs no privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality low, integrity none, availability none.

CVSS metrics in full

  • Privileges required: None — an unauthenticated stranger can try it.
  • User interaction: None — nobody has to be tricked into anything.
  • Scope: Unchanged — the damage stays inside the vulnerable component.
  • Confidentiality impact: Low — limited, and the attacker does not choose what is affected.
  • Integrity impact: None.
  • Availability impact: None.
