zlt2000 microservices-platform through 6.0.0 contains an unverified password change vulnerability in the PUT /users/password endpoint that allows authenticated users to change any account password by omitting the current password check. Attackers can supply an arbitrary user id in the request body and a new password to overwrite credentials of any non-administrator account without verification.
AnalysisAI
Authenticated users of zlt2000 microservices-platform through 6.0.0 can overwrite the password of any non-administrator account by calling the PUT /users/password endpoint with an arbitrary user id and a new password, because the server never verifies the current password. The flaw is network-reachable, low-complexity, and requires only a low-privilege login session (CVSS 4.0 base 8.7; assessed CVSS 3.1 AV:N/AC:L/PR:L/UI:N/C:H/I:H/A:L), and publicly available exploit code exists. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires a valid authenticated session as a low-privilege user (PR:L) on the zlt2000 microservices-platform (through 6.0.0); the attacker calls the PUT /users/password endpoint and supplies an arbitrary target user id plus a new password. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:L, base 8.7) describes a network-reachable, low-complexity flaw requiring only a low-privilege authenticated account - no user interaction. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patch identified at time of analysis, so remediation must begin with compensating controls while a fixed release is awaited. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all zlt2000 microservices-platform deployments and confirm whether any instance is version 6.0.0 or earlier; restrict network access to the PUT /users/password endpoint via reverse proxy, WAF, or firewall rules so only trusted administrative networks or identities can call it, and enable logging and alerting for that endpoint to detect arbitrary user ID password changes. …
