The vulnerability affects versions 12.2.3 through 12.2.15. An unauthenticated attacker with network access via HTTPS can exploit this flaw, gaining unauthorized access to sensitive data and potentially modifying or deleting critical information within the Oracle Payments system. This vulnerability poses a significant risk to organizations using affected versions of Oracle E-Business Suite, as it could lead to data breaches, financial loss, and reputational damage. Successful exploitation grants the attacker unauthorized creation, deletion, or modification access to critical data or complete access to all Oracle Payments accessible data.

Attack Chain

  1. The attacker identifies an Oracle E-Business Suite instance running a vulnerable version of Oracle Payments (12.2.3-12.2.15).
  2. The attacker gains network access to the target system via HTTPS.
  3. The attacker crafts a malicious HTTPS request targeting the File Transmission component.
  4. Due to insufficient access controls or input validation, the attacker's request bypasses authentication.
  5. The vulnerability in the File Transmission component allows the attacker to execute arbitrary code or access sensitive data.
  6. The attacker gains unauthorized access to critical data within Oracle Payments.
  7. The attacker creates, deletes, or modifies data, potentially causing financial loss or disruption of services.
  8. The attacker may escalate privileges or move laterally within the network to further compromise other systems.

Impact

Successful exploitation of CVE-2026-46818 allows an unauthenticated attacker to gain unauthorized access to and modify critical data within Oracle Payments. This can lead to significant data breaches, financial losses, and disruption of financial transactions. The impact could be substantial, potentially affecting thousands of organizations that rely on the Oracle E-Business Suite for payment processing. Data integrity could be compromised, leading to incorrect financial records and legal liabilities.

Recommendation

  • Apply the latest patch or upgrade to a version of Oracle E-Business Suite that is not affected by CVE-2026-46818, as recommended by Oracle.
  • Deploy the Sigma rule Detect CVE-2026-46818 Exploitation Attempt via Oracle Payments to identify and block malicious requests targeting the vulnerable File Transmission component.
  • Monitor network traffic for suspicious HTTPS requests targeting Oracle Payments from untrusted sources, using the network connection log source.
  • Implement strict access controls to limit network access to Oracle Payments, reducing the attack surface.
  • Regularly review and audit Oracle Payments configurations to identify and remediate any security weaknesses.

Specifically, the issue resides in the File Transmission component. The vulnerability impacts versions 12.2.3 through 12.2.15. This is an easily exploitable vulnerability, as it requires no authentication and can be triggered via network access over HTTP. Successful exploitation of this vulnerability can lead to a complete takeover of Oracle Payments, allowing attackers to gain full control over the application and its data. Defenders should prioritize patching affected systems.

Attack Chain

  1. The attacker identifies an Oracle E-Business Suite instance running a vulnerable version of Oracle Payments (12.2.3 - 12.2.15).
  2. The attacker crafts a malicious HTTP request targeting the File Transmission component.
  3. The request bypasses authentication checks due to the nature of the vulnerability.
  4. The crafted request exploits a flaw in how the File Transmission component handles file operations.
  5. The attacker leverages the file operation vulnerability to execute arbitrary code on the server.
  6. The attacker gains initial access to the Oracle Payments server with the privileges of the application user.
  7. The attacker escalates privileges within the Oracle Payments system, potentially gaining root or administrator access.
  8. The attacker achieves a full takeover of Oracle Payments, enabling them to access sensitive data, modify configurations, and potentially pivot to other systems within the network.

Impact

Successful exploitation of CVE-2026-46817 allows an unauthenticated attacker to completely compromise an Oracle Payments instance. Given the role of Oracle Payments in managing financial transactions within the E-Business Suite, this could lead to significant financial losses, data breaches, and disruption of business operations. This vulnerability affects versions 12.2.3-12.2.15, potentially impacting a large number of organizations using Oracle E-Business Suite for their financial operations.

Recommendation

  • Apply the Oracle patch for CVE-2026-46817 to remediate the vulnerability in the File Transmission component of Oracle Payments.
  • Deploy the Sigma rule "Detect CVE-2026-46817 Exploitation Attempt - HTTP Request to Oracle Payments File Transmission" to identify potential exploitation attempts targeting the vulnerable component.
  • Monitor web server logs for suspicious HTTP requests to the File Transmission component, specifically looking for unusual parameters or file operations.
  • Implement network segmentation to limit the impact of a successful attack on Oracle Payments by restricting access to other critical systems.
