jshERP through 3.6 fails to properly validate user privileges in SystemConfigService.updateSystemConfig, allowing authenticated users to modify tenant system configuration. Attackers can rewrite or delete tenant-wide settings covering company identity, stock rules, approval behavior, and printing configuration through the systemConfig endpoint.

AnalysisAI
Missing authorization in jshERP through version 3.6 lets authenticated low-privilege users rewrite or delete tenant-wide system configuration through the systemConfig endpoint, because SystemConfigService.updateSystemConfig performs no privilege check. Successful abuse corrupts the integrity of company identity, stock rules, approval behavior, and printing configuration, with a secondary risk of disrupting tenant operations; there is no confidentiality exposure reported. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires an authenticated low-privilege account on the target jshERP tenant (PR:L); the attacker then reaches SystemConfigService.updateSystemConfig via the systemConfig endpoint, which performs no privilege validation. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine but moderate-priority issue rather than a critical emergency. … 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 fixed version is identified in the available data, so the primary action is to restrict access to the affected systemConfig endpoint rather than rely on an upgrade: enforce role- and tenant-aware authorization on SystemConfigController/SystemConfigService.updateSystemConfig (either by patching the source directly or via an upstream fix once published), and verify against the latest jshERP repository at https://github.com/jishenghua/jshERP; the referenced vulncheck.com advisory is the best tracking source for patch status. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, restrict access to the systemConfig endpoint to authorized administrative roles only by implementing a reverse proxy or web application firewall rule, and review logs for any recent unauthorized configuration changes. …
