Exploitation Conditions

No special conditions - remote unauthenticated exploitation against a reachable deployment of ZongXR SuperMarket 1.0.0.0. The attacker only needs network access to the OrderController.deleteOrder endpoint and must supply an orderId argument; no credentials, user interaction, or non-default configuration are required (AV:N/AC:L/AT:N/PR:N/UI:N). The only real limiting factor is exposure: the product is an obscure hobby project rarely deployed in production, and the impact is confined to order-record deletion (integrity/availability), not confidentiality or code execution.

Impact

Signals are consistent but point to a low-to-moderate real-world priority. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N) describes a trivially reachable, unauthenticated, remote flaw, but the vendor-assigned impact is deliberately limited to VI:L/VA:L (partial integrity and availability, no confidentiality), yielding a 6.9 medium score rather than a critical one - consistent with the CWE-306 missing-authentication condition on a single order-deletion endpoint rather than full system takeover. SSVC-style exploit maturity is E:P (Proof-of-Concept), and a public exploit is confirmed via the GitHub issue, so 'publicly available exploit code exists' - but there is no EPSS score, no CISA KEV listing, and no evidence of active exploitation, so this is POC availability, NOT confirmed in-the-wild use. The dominant mitigating factor is prevalence: ZongXR SuperMarket is an obscure GitHub project (version 1.0.0.0) with no meaningful production footprint, and the maintainer was notified via an issue report but has not responded, implying no patch. Net: a genuine, easily exploitable unauthenticated flaw, but the near-zero deployment base makes it a low operational priority for most defenders rather than a high-CVSS-but-overrated issue.

Exploit ScenarioDerived

A remote, unauthenticated attacker sends a crafted HTTP request to the OrderController.deleteOrder endpoint, supplying an arbitrary orderId value. Because the endpoint performs no authentication or authorization check (CWE-306), the attacker deletes other users' orders at will, corrupting order data and degrading application availability. A public proof-of-concept is already documented in the project's GitHub issue tracker (issue #31).

AnalysisAIv1 – Oct 01, 2026

Unauthenticated remote attackers can delete arbitrary order records in ZongXR SuperMarket 1.0.0.0 because the OrderController.deleteOrder endpoint lacks authentication checks (CWE-306). Publicly available exploit code exists (GitHub issue #31), and the project maintainer has not responded to the report. With a CVSS 4.0 score of 6.9 (medium) and an independent assessment confirming only low integrity and availability impact, the vulnerability poses a low-to-moderate risk, primarily limited by the product's rare deployment in production environments.

RemediationAI

No vendor-released patch is available at the time of analysis, as the project maintainer has not responded to the issue report (GitHub issue #31). To mitigate, implement authentication and authorization checks on the OrderController.deleteOrder endpoint (e.g., using Spring Security annotations) as the definitive fix. If immediate code changes are not possible, restrict network access to the order deletion endpoint via firewall rules or an API gateway, or disable the order deletion functionality entirely if it is not business-critical. Deploying the application behind an authenticating reverse proxy that enforces credentials for all delete requests can also help, but this adds latency and configuration complexity. Monitor logs for unauthorized deletion attempts. Given the public exploit, prioritize patching if the application is exposed.

Technical ContextAI · show details

The vulnerability is a classic Missing Authentication for Critical Function (CWE-306) in a Java Spring Boot application. The OrderController.deleteOrder method in the order microservice (order/src/main/java/com/supermarket/order/controller/OrderController.java) processes an orderId parameter and deletes the corresponding order record without verifying the requester's identity or permissions. The CPE string cpe:2.3:a:zongxr:supermarket:*:*:*:*:*:*:*:* indicates that all versions of the ZongXR SuperMarket product are potentially affected, though the reported version is 1.0.0.0. Because the endpoint is exposed over the network and requires no credentials, any remote attacker who can reach the service can invoke the deletion function, leading to loss of order data (integrity and availability impact). The public exploit code in GitHub issue #31 demonstrates the attack vector.

DescriptionCVE.org

A security flaw has been discovered in ZongXR SuperMarket 1.0.0.0. Affected by this issue is the function OrderController.deleteOrder of the file order/src/main/java/com/supermarket/order/controller/OrderController.java of the component Order Deletion Endpoint. Performing a manipulation of the argument orderId results in missing authentication. The attack is possible to be carried out remotely. The exploit has been released to the public and may be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.
