Any authenticated low-priv user (PR:L) can remotely read every user's password hash with no interaction; direct impact is pure confidentiality (C:H), integrity/availability only follow after offline cracking so I:N/A:N at base.

8DescriptionCVE.org
jshERP through 3.6 fails to redact password hashes in the /user/info endpoint, allowing authenticated users to retrieve unsalted MD5 password digests for any user. Attackers can request arbitrary user information by supplying user IDs to obtain password hashes usable for offline cracking or direct authentication bypass.

AnalysisAI
jshERP through 3.6 exposes unsalted MD5 password hashes via the /user/info endpoint, allowing any authenticated user to retrieve password digests for arbitrary users by supplying their user IDs. This information disclosure (CWE-200) affects all versions up to 3.6, and publicly available exploit code exists. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires a valid authenticated jshERP session at any privilege level (PR:L) - the /user/info endpoint performs no per-object authorization, so a low-privilege user can request any other user's record by supplying their user ID. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine, moderately-serious data-exposure flaw that is easy to exploit once an attacker holds any valid account. … 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. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, restrict network access to the /user/info endpoint to only essential personnel, enforce strong password policies (minimum 12 characters, complexity, and no reuse), and enable detailed logging for user ID enumeration attempts; within 7 days, deploy a web application firewall rule to block enumeration patterns on the /user/info endpoint, conduct a password audit and force reset for all users with weak or reused passwords, and implement real-time monitoring for anomalous access to user information; within 30 days, plan migration to a supported version of jshERP beyond 3.6 when a vendor patch becomes available, and consider multi-factor authentication and network segmentation as interim mitigations until a patch is released.
