CVE-2026-110114 in oms-erp
Summary
by MITRE • 10/13/2026
FJ-OMS oms-erp through PRE contains a missing authentication vulnerability that allows unauthenticated attackers to delete and rebuild product search indexes by calling public es-test maintenance endpoints in skyer-goods. Attackers can repeatedly request /v1/goods/sku/es-test to empty the shared goods_sku_index_01 index for all tenants and force full-table reloads, degrading search availability.

The vulnerability identified as FJ-OMS oms-erp through PRE represents a critical authentication bypass within the Skyer Goods module of an Enterprise Resource Planning system. This flaw stems from the improper implementation of access controls on specific maintenance endpoints designed for Elasticsearch index testing and rebuilding. Specifically, the endpoint /v1/goods/sku/es-test is exposed publicly without requiring any form of user authentication or authorization checks. In a properly secured environment, administrative functions that modify core data structures such as search indexes should be restricted to authorized personnel with appropriate privileges. The absence of these controls allows unauthenticated actors on the network to interact directly with this endpoint, effectively treating sensitive operational commands as public API calls.
From a technical perspective, the exploitation mechanism involves sending HTTP requests to the /v1/goods/sku/es-test URL without providing valid session tokens or credentials. When triggered, this action initiates a process that empties and subsequently rebuilds the shared goods_sku_index_01 index. This operation is particularly dangerous because it affects all tenants in a multi-tenant architecture rather than isolating changes to individual user contexts. The rebuilding of search indexes typically involves heavy database queries and resource-intensive operations as the system scans product data to reconstruct the searchable structure. By forcing this process repeatedly, an attacker can induce significant computational load on the backend servers responsible for maintaining these indices.
The operational impact of this vulnerability is severe, primarily manifesting as a denial of service against search functionality across the entire platform. Each invocation of the endpoint causes the shared index to be cleared and then rebuilt from scratch. During the rebuilding phase, which can take considerable time depending on the volume of product data, search queries will fail or return incomplete results because the underlying Elasticsearch cluster is occupied with indexing tasks rather than serving requests. This leads to a degradation in service availability where customers cannot find products, effectively halting commercial operations that rely on accurate and immediate search capabilities. Furthermore, the repeated emptying and rebuilding cycles can lead to resource exhaustion, potentially causing system instability or crashes if not monitored and throttled by infrastructure-level safeguards.
This vulnerability aligns with CWE-287, which describes Improper Authentication, as the application fails to verify identity before executing privileged operations. It also relates to CWE-611, Information Exposure Through an Error Message, if the endpoint returns detailed error information that aids further exploitation, though the primary issue is the lack of access control. In terms of MITRE ATT&CK mapping, this behavior corresponds to T1499 Endpoint Denial of Service and potentially T1078 Valid Accounts if the attacker later escalates privileges using credentials obtained through other means, but in its current form, it is a direct exploitation of missing authentication leading to service disruption. The attack vector is classified as Network-based since it requires only network access to reach the vulnerable endpoint, making it exploitable by remote attackers who have connectivity to the application server.
Mitigation strategies must focus on immediate remediation and long-term architectural improvements. Immediately, the /v1/goods/sku/es-test endpoint should be disabled or restricted behind a firewall rule that limits access to trusted internal IP addresses only if such maintenance is still required for operational purposes. Ideally, this endpoint should be removed entirely from public-facing interfaces as it serves no legitimate purpose for end-users and poses excessive risk. For any remaining administrative endpoints, strict authentication mechanisms must be enforced using industry-standard protocols like OAuth2 or JWT with robust validation logic. Additionally, implementing rate limiting on all API endpoints can mitigate the impact of repeated requests even if an attacker manages to bypass initial controls. Monitoring tools should be configured to alert security teams when unusual spikes in index rebuild operations occur, allowing for rapid response before significant service degradation takes place. Regular penetration testing and code reviews focusing on authentication flows are essential to prevent similar oversights in future development cycles.
