Vulnerability from github
Summary
An unauthenticated information disclosure vulnerability exists in the PSU deployment of HAX CMS via the haxPsuUsage API endpoint. This allows any remote unauthenticated user to retrieve a full list of PSU websites hosted on HAX CMS. When chained with other authorization issues (e.g., HAX-3), this could assist in targeted attacks such as unauthorized content modification or deletion.
Details
The endpoint https://open-apis.hax.cloud/api/services/stats/haxPsuUsage returns a list of websites on the PSU instance of HAX CMS. This endpoint is exposed without any authentication or authorization checks.
The source of the issue is in the haxPsuUsage.js file, which appears to directly serve the site listing without verifying user identity or access level. This enables anyone with the endpoint URL to enumerate all site instances under the PSU deployment.
This endpoint may have originally been used for internal or statistical purposes but is now publicly accessible, representing a privacy and enumeration risk.
PoC
To reproduce this vulnerability:
- Open a terminal or browser.
- Send a GET request to the following endpoint: ```bash curl https://open-apis.hax.cloud/api/services/stats/haxPsuUsage
Impact
The haxPsuUsage endpoint exposes a full list of PSU HAX CMS websites to any unauthenticated user, allowing external actors to enumerate all sites under the PSU domain. This alone represents an information disclosure vulnerability.
When chained with the Lack Of Authorization Checks CVE, which involves missing authorization checks on key API endpoints, the risk escalates significantly. An authenticated attacker can:
- Modify or delete other users' sites via:
createNode(),saveNode(),deleteNode()- Access sensitive metadata or credentials:
getConfig(),downloadSite()- Clone or remove entire sites:
cloneSite(),deleteSite(),archiveSite()
Combined, these issues allow a low-privileged user to fully compromise any site in the PSU HAX CMS instance.
This vulnerability chain puts content integrity, availability, and confidentiality at risk for potentially hundreds of PSU academic, instructional, and departmental sites.
