Oracle Mobile Field Service: Improper access control
Summary
The Oracle Mobile Field Service module of Oracle E-Business Suite (component Internal Operations) contains an access control flaw (CWE-284). An attacker with a low-privileged account and network access via HTTP can, according to the CVSS vector, take over the module with high impact to confidentiality, integrity and availability. No user interaction is required, and the record is still awaiting NVD analysis.
Affected
- Oracle Mobile Field Service in Oracle E-Business Suite, versions 12.2.3 to 12.2.15
Fixed in
Unknown. Oracle's October 2026 Critical Patch Update and MOS article KA1818 are the references for the patch; a My Oracle Support login is required.
Workaround
Unknown. No vendor-documented interim workaround found.
- Until patched, restrict HTTP access to the Mobile Field Service pages
- Reduce and review the accounts that hold low privileges on the module
Exploitation
Unknown. No exploitation reported in the sources reviewed. CISA SSVC lists exploitation as none. No public proof of concept found; the search was limited.
Our recommendation
- Check whether the client runs EBS 12.2 in the affected range with Mobile Field Service
- Apply the patch from Oracle's October 2026 CPU advisory and KA1818; prioritise if the module is reachable from the internet
- Review low-privileged accounts and restrict HTTP access until patched
- Monitor access logs of the module
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
