Brute-forceable password change userId parameter in Flytxt NEON-dX

IdentifiersCVE-2023-34732CWE-307· Improper Restriction of Excessive…

CVE-2023-34732 affects Flytxt NEON-dX v0.0.1-SNAPSHOT-6.9-qa-2-9-g5502a0c. According to the provided content, the issue is in the userId parameter used by the change password function. The flaw allows an attacker to conduct brute-force attacks to discover user passwords. Based on the available information, the vulnerability appears to stem from insufficient restriction of excessive authentication or password-related attempts associated with that parameter and workflow. No further implementation details about the specific function, request handling, or server-side validation logic are available in the provided content.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows an attacker to brute-force and discover user passwords. This can lead to unauthorized access to affected user accounts and any data or application functionality available to those accounts. The provided content does not establish broader impacts such as code execution or privilege escalation beyond account compromise.

Mitigation

If you can’t patch tonight, do this now.

If an immediate fix is not available, reduce exposure by enforcing rate limits at the application, API gateway, WAF, or reverse-proxy layer for the affected password change endpoint; require MFA for affected accounts where possible; monitor for repeated requests targeting the change password function; temporarily restrict access to the endpoint to trusted networks or authenticated sessions only if operationally feasible; and reset passwords for potentially affected accounts if compromise is suspected.

Remediation

Patch, then assume compromise.

Implement effective anti-brute-force protections in the change password workflow, particularly around handling of the userId parameter. This should include server-side rate limiting, account lockout or progressive delays after repeated failed attempts, monitoring and alerting on repeated password-guessing behavior, and ensuring the password change process requires robust re-authentication and validation tied to the authenticated user rather than a user-supplied identifier alone. Upgrade to a vendor-fixed version if one is available; specific fixed-version information is not provided in the supplied content.
