Threat & Defense at a Glance

What attackers do: exploitation maps to Exploit Public-Facing Application (T1190). What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

AC-14 Permitted Actions Without Identification or Authentication good match

prevent

Directly limits permitted actions without identification or authentication, preventing unauthenticated access to the /rest/rights/ endpoint.

AC-3 Access Enforcement good match

prevent

Enforces approved authorizations for logical access, ensuring the API endpoint requires authentication to access sensitive rights information.

AC-6 Least Privilege partial match

prevent

Implements least privilege to restrict access to sensitive information only to authorized users, mitigating unauthorized disclosure via the unauthenticated endpoint.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

Why these techniques?

Direct unauthenticated network access to public REST API endpoint enables exploitation of public-facing application for sensitive data disclosure.

Confidence: HIGH · MITRE ATT&CK Enterprise v18.1

NVD Description

The /rest/rights/ REST API endpoint in Becon DATAGerry through 2.2.0 contains an Incorrect Access Control vulnerability. An attacker can remotely access this endpoint without authentication, leading to unauthorized disclosure of sensitive information.

Deeper analysisAI

CVE-2024-50967 is an Incorrect Access Control vulnerability (CWE-862) affecting the /rest/rights/ REST API endpoint in Becon DATAGerry through version 2.2.0. This flaw allows remote access to the endpoint without authentication, resulting in the unauthorized disclosure of sensitive information. The vulnerability has a CVSS v3.1 base score of 6.5 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N), indicating medium severity with network accessibility, low attack complexity, no required privileges, user interaction, and high confidentiality impact.

A remote attacker with no privileges can exploit this vulnerability by directly accessing the /rest/rights/ endpoint over the network. Although user interaction is required per the CVSS vector, the core issue enables unauthenticated retrieval of sensitive data, potentially exposing rights or permissions information that could aid further attacks or reconnaissance.

Mitigation guidance and additional details are provided in official advisories, including the DATAGerry REST API documentation at https://datagerry.readthedocs.io/en/latest/api/rest/user-management.html#rights, a GitHub repository at https://github.com/0xByteHunter/CVE-2024-50967, and a Medium article by the discoverer at https://medium.com/@0xbytehunter/my-first-cve-discovery-of-broken-access-control-in-the-datagerry-platform-7b0404f88a43. Security practitioners should review these resources for patching instructions and workarounds, as DATAGerry versions through 2.2.0 remain vulnerable.
