socialstream: Improper Authentication

CVE-2024-56329 is a high-severity improper authentication vulnerability in socialstream from Joelbutcher, with a CVSS 4.0 base score of 8.9 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, but only if a user takes part, for example by opening a link or file. Affected socialstream versions: < 6.2.0. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.58% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Check which version of socialstream you run against the affected versions below, and install the vendor's latest release.
  2. Read the advisory on github.com for workarounds and exact fixed builds.
  3. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
  4. Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description

Socialstream is a third-party package for Laravel Jetstream. It replaces the published authentication and profile scaffolding provided by Laravel Jetstream, with scaffolding that has support for Laravel Socialite. When linking a social account to an already authenticated user, the lack of a confirmation step introduces a security risk. This is exacerbated if ->stateless() is used in the Socialite configuration, bypassing state verification and making the exploit easier. Developers should ensure that users explicitly confirm account linking and avoid configurations that skip critical security checks. Socialstream v6.2 introduces a new custom route that requires a user to "Confirm" or "Deny" a request to link a social account. Users are advised to upgrade. There are no known workarounds for this vulnerability.

The underlying weakness: Improper Authentication

When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.

How developers prevent this class of flaw

  • Use an authentication framework or library such as the OWASP ESAPI Authentication feature.
