CVE-2025-69615
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIncorrect Access Control via missing 2FA rate-limiting allowing unlimited brute-force retries and full MFA bypass with no user interaction required. Affected Product: Deutsche Telekom AG Telekom Account Management Portal, versions before 2025-10-24, fixed 2025-11-03.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Telekom Account Management Portal lacked rate limiting on its two-factor authentication (2FA) mechanism, allowing attackers to perform unlimited brute-force attempts against the 2FA verification endpoint. This vulnerability enables a complete MFA bypass without requiring any user interaction, giving attackers the ability to guess valid 2FA codes and take over accounts.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if Telekom Account Management Portal is deployedReview your application's software inventory or check the running services to confirm the Telekom Account Management Portal is installed in your environmentAffected if The Telekom Account Management Portal is present in your environment
-
Check the installed version of the portalLocate the version information for the Telekom Account Management Portal (typically found in about page, configuration file, or software metadata) and compare it against the affected range: versions <= 2025-10-24Affected if The installed version is 2025-10-24 or earlier
-
Verify if rate limiting is configured on the 2FA endpointExamine your web server, application firewall, or the portal's security configuration to determine whether rate limiting rules are applied to the 2FA verification endpoint (commonly the endpoint handling 2FA code submission)Affected if No rate limiting is configured or enforced on the 2FA submission endpoint
-
Check for account lockout or brute-force protection policiesReview authentication security policies for the portal to see if account lockout thresholds or brute-force detection mechanisms are defined for failed 2FA attemptsAffected if No account lockout policy or brute-force protection exists for 2FA failures
Your environment is affected if the Telekom Account Management Portal version is 2025-10-24 or earlier AND rate limiting or account lockout protections are not implemented on the 2FA verification endpoint.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedApply the vendor patch released on 2025-11-03 (or update to version after 2025-10-24). Additionally, implement aggressive rate limiting and account lockout policies on all authentication endpoints, including 2FA submission pages.
Version released 2025-11-03 or later
- Upgrade the Deutsche Telekom AG Telekom Account Management Portal to version released on or after 2025-11-03
- After upgrading, verify that rate-limiting is now enforced on the 2FA/MFA authentication endpoints
- Confirm that excessive authentication attempts are now properly restricted per the CWE-307 fix
