Threat & Defense Details

Likely Mitigating ControlsAI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

SA-19 Component Authenticity

addresses: CWE-295

When certificates are used to establish component provenance, the control requires correct certificate validation procedures.

SC-17 Public Key Infrastructure Certificates

addresses: CWE-295

Mandates approved trust anchors and issuance policies, directly preventing acceptance of unvalidated or untrusted certificates.

SC-45 System Time Synchronization

addresses: CWE-295

Correct system time is required for proper enforcement of certificate notBefore/notAfter dates and time-based revocation checks.

MITRE ATT&CK Enterprise TechniquesAI

T1557 Adversary-in-the-Middle Credential Access

Adversaries may attempt to position themselves between two or more networked devices using an adversary-in-the-middle (AiTM) technique to support follow-on behaviors such as [Network Sniffing](https://attack.

Why these techniques?

Disabling certificate validation (rejectUnauthorized: false) directly enables successful Adversary-in-the-Middle attacks on outbound connections, allowing interception of sensitive data.

NVD Description

An issue in Sunbird-Ed SunbirdEd-portal v1.13.4 allows attackers to obtain sensitive information. The application disables TLS/SSL certificate validation by setting 'rejectUnauthorized': false in HTTP request options

Deeper analysisAI

CVE-2025-70029 affects Sunbird-Ed's SunbirdEd-portal version 1.13.4, where the application disables TLS/SSL certificate validation by explicitly setting 'rejectUnauthorized': false in HTTP request options. This configuration leads to improper certificate validation (CWE-295), enabling attackers to obtain sensitive information. The vulnerability carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) and was published on 2026-02-11.

Any network-accessible attacker can exploit this vulnerability with low complexity, requiring no privileges, user interaction, or scope changes. Exploitation allows high-impact confidentiality breaches, such as intercepting sensitive data via man-in-the-middle attacks, as the lack of certificate validation exposes outbound HTTP requests to tampering or eavesdropping.
