CVE-2022-39231: Parse Server subject to Improper Authentication allowing Auth adapter app ID validation to be circumvented

Noroxi assessment

Priority: Monitor (action score 14/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 0.52% (FIRST EPSS).
Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. Special conditions such as timing or configuration are required.
Fixed version: parse-server (npm) 5.2.7, 4.10.16.

Low priority for now. Upgrade to parse-server (npm) 5.2.7, 4.10.16 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. In versions prior to 4.10.16, or from 5.0.0 to 5.2.6, validation of the authentication adapter app ID for _Facebook_ and _Spotify_ may be circumvented. Configurations which allow users to authenticate using the Parse Server authentication adapter where `appIds` is set as a string instead of an array of strings authenticate requests from an app with a different app ID than the one specified in the `appIds` configuration. For this vulnerability to be exploited, an attacker needs to be assigned an app ID by the authentication provider which is a sub-set of the server-side configured app ID. This issue is patched in versions 4.10.16 and 5.2.7. There are no known workarounds.

CVSS vector

Root cause

Authentication is added route by route instead of being enforced in one place. When a route added later bypasses the shared middleware, the session check never runs for it.
