Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-69615 is an incorrect access control vulnerability (CWE-307) stemming from missing rate-limiting on two-factor authentication (2FA) in the Deutsche Telekom AG Telekom Account Management Portal. This flaw allows unlimited brute-force retries on 2FA, enabling full multi-factor authentication (MFA) bypass without any user interaction. It affects versions of the portal prior to the update on 2025-10-24, with a fix applied on 2025-11-03. The vulnerability carries a CVSS v3.1 base score of 9.1 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N), indicating critical severity due to high impacts on confidentiality and integrity.
Remote attackers require no privileges or user interaction to exploit this issue over the network with low complexity. By repeatedly attempting brute-force guesses against the 2FA mechanism without rate limits, adversaries can fully bypass MFA protections, gaining unauthorized access to affected user accounts in the Telekom Account Management Portal and potentially compromising sensitive account data.
Mitigation requires updating the Telekom Account Management Portal to the version incorporating the fix released on 2025-11-03. Additional details are available in Telekom's security acknowledgements at https://www.telekom.com/en/company/data-privacy-and-security/news/acknowledgements-358300#R and a technical gist at https://gist.github.com/ethicalrohitt/b3e6d071aac8530459e8b3a5720bb832. The CVE was published on 2026-03-10T18:18:01.740.

Mitigating Controls (NIST 800-53 r5) AI
AC-7 directly enforces limits on consecutive failed logons, structurally blocking brute-force exploitation of the weakness.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Authentication enforcement directly includes lockout, throttling, and MFA policies that prevent brute-force attempts.
Behavioral monitoring of authentication activity can detect excessive failed attempts after they occur.
Generating auth logs enables later detection or forensics but does not itself restrict attempts.
