Oracle E-Business Suite Integrated SOA Gateway: Improper access control
Summary
Oracle E-Business Suite Integrated SOA Gateway (component SOA Provider) versions 12.2.3 to 12.2.15 contain a flaw in access control (CWE-284). An unauthenticated attacker with HTTP network access can exploit it with low complexity and no user interaction. Successful attacks can grant unauthorized access to critical data the gateway can reach, with a scope change that may also affect other products.
Affected
- Oracle E-Business Suite Integrated SOA Gateway, SOA Provider component
- Supported versions 12.2.3 to 12.2.15
Fixed in
- Oracle Critical Patch Update of October 2026 (20 Oct 2026)
- Specific patch number for this CVE: Unknown.
- My Oracle Support Note KA923 is cited for the required patches; it has not been confirmed to cover this CVE.
Workaround
- No vendor workaround known.
- Interim measure if patching is delayed: restrict network access to SOA Gateway endpoints to known integration partners and log HTTP access to them.
Exploitation
- No exploitation reported in the sources as of 1 Nov 2026.
- No public proof of concept known.
- Not listed in CISA KEV on 21 Oct 2026; current KEV status not rechecked.
Our recommendation
- Apply the October 2026 Oracle CPU to the EBS application, Database and Fusion Middleware layers.
- Apply the whole CPU, not only this CVE, as other unauthenticated EBS flaws in it score higher.
- Check whether SOA Gateway endpoints are reachable from the internet and treat exposed instances as high priority.
- Restrict access to known partners and monitor HTTP access logs to the endpoints.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
