| Exploitation Conditions | Exploitation requires a valid Oracle E-Business Suite account with at minimum low-privilege access (PR:L per CVSS), reachable to the MWA Terminal Server component over HTTP on the network. The MWA Terminal Server sub-component must be deployed and network-accessible - organizations that have not deployed the Mobile Warehouse Application feature or have restricted HTTP access to the MWA endpoint are not directly exposed. No specific non-default configuration is required beyond having MWA enabled; versions 12.2.3 through 12.2.15 are all within scope. Exploitation is bounded to confidentiality only - no write access, data modification, or service disruption is achievable through this vector. The limiting factor is the authentication requirement: unauthenticated external attackers without any Oracle EBS credentials cannot directly exploit this flaw based on the PR:L CVSS rating. |
| Impact | The CVSS 6.5 Medium score sits below the critical threshold, but several factors elevate real-world priority: Oracle's own advisory language describes this as 'easily exploitable,' the attack vector requires only a valid low-privilege account over standard HTTP with no complexity or user-interaction prerequisites, and the confidentiality impact is rated High - meaning complete data exposure within the application's accessible scope. The 'Authentication Bypass' tag suggests that minimal credentials (e.g., a warehouse operator account) may be sufficient to access data intended for administrative or cross-tenant roles, compounding the impact beyond what a raw C:H rating conveys in isolation. No EPSS score was available to quantify exploitation probability, and the absence of a KEV listing and public exploit indicates no confirmed widespread opportunistic attacks at time of analysis - however, the low technical barrier means even a mid-sized municipal IT team in olsztyn running Oracle E-Business Suite with MWA enabled should treat this as an urgent patching priority rather than a deferred item. The missing CWE is a data gap that prevents confirming the precise bypass mechanism; root cause remains inferred from available tags and CVSS alone. |
| Exploit ScenarioDerived | An attacker holding any valid low-privilege Oracle E-Business Suite account - such as a warehouse operator, scanner terminal user, or read-only reporting credential - sends a crafted HTTP request directly to the MWA Terminal Server endpoint. The authorization bypass allows the account to read data outside its assigned scope, potentially exposing inventory records, customer orders, financial transactions, or other business-critical data accessible to the Mobile Application Server. No public proof-of-concept code has been identified, but the low attack complexity means that any user familiar with Oracle EBS HTTP APIs could construct an exploit without specialized tooling. |

Alert meAnalysisAIv1 – Aug 19, 2026
Unauthorized data disclosure in Oracle Mobile Application Server's MWA Terminal Server component affects all supported E-Business Suite deployments running versions 12.2.3 through 12.2.15. Low-privileged network attackers with HTTP access can exploit an authorization bypass to gain complete read access to all data within the Mobile Application Server's scope - including sensitive warehouse, inventory, and business records. No public exploit has been identified and this vulnerability is not listed in the CISA KEV catalog, but Oracle's advisory language explicitly flags it as 'easily exploitable,' reducing the practical barrier significantly.
RemediationAI
Apply the patches included in Oracle's Critical Security Patch Update for August 2026, available at https://www.oracle.com/security-alerts/cspuaug2026.html. Customers running Oracle E-Business Suite versions 12.2.3 through 12.2.15 should follow Oracle's CPU patch application instructions specific to the Mobile Application Server component; an exact patched version number is not independently confirmed beyond the CPU reference, so the advisory should be consulted directly for patch sequencing. As a compensating control pending patch deployment, network access to the MWA Terminal Server's HTTP endpoint should be restricted at the firewall or load-balancer level to only authorized warehouse terminal IP ranges, reducing the pool of potential attackers to known devices. Organizations that do not use Oracle's mobile warehouse functionality should consider disabling the MWA Terminal Server component entirely, accepting the operational trade-off of losing mobile terminal support in exchange for eliminating the attack surface. No additional workarounds are confirmed by vendor advisory data.

Technical ContextAI · show details
Oracle Mobile Application Server (MAS) is the middleware layer within Oracle E-Business Suite that supports mobile warehouse and field operations via its MWA (Mobile Warehouse Application) Terminal Server component, exposed over HTTP. The affected CPE range spans Oracle E-Business Suite versions 12.2.3 through 12.2.15. The CVSS vector (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N) indicates a purely network-accessible, low-complexity confidentiality flaw with no scope change. The 'Authentication Bypass' tag applied to this CVE by EUVD suggests the root cause is an authorization control failure - likely within the MWA Terminal Server's session or access-control logic - that allows a low-privilege authenticated user to reach data beyond their assigned permission boundary. No CWE has been formally assigned, which limits root-cause classification to inference from the tag and CVSS metadata.
