CWE

KEV

CWE ID	Description
CWE-89	The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
CWE-200	The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
CWE-284	The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.

Attack-Flow Graph

Executive Summary

This is a vulnerability in Oracle Common Applications Calendar within Oracle E-Business Suite. It affects versions 12.2.3 to 12.2.15. A low-privileged attacker with network access via HTTP can exploit it to gain unauthorized access to data, modify or delete data, and cause partial denial of service.

Detection Guidance

Detection requires monitoring Oracle E-Business Suite logs for unusual HTTP access to the Calendar Synchronizations component. Check for repeated failed authentication attempts or unexpected data modification requests in the Oracle Common Applications Calendar module.

Impact Analysis

If you use the affected Oracle Common Applications Calendar versions, an attacker could read, modify, or delete some of your calendar data. They could also disrupt calendar services, leading to partial unavailability.

Compliance Impact

This vulnerability could potentially impact compliance with GDPR and HIPAA due to unauthorized data access and modification risks. Unauthorized read, update, or delete access to calendar data may violate confidentiality requirements under both regulations. The partial denial of service could also disrupt access to critical data, affecting availability standards.

Mitigation Strategies

Apply the latest Oracle Critical Patch Update for E-Business Suite. Restrict network access to the Calendar Synchronizations component via firewall rules. Monitor and audit user permissions in the Oracle Common Applications Calendar module to ensure least privilege access.
