AI Analysis

Impact

This vulnerability permits an unauthenticated attacker with network access over HTTP to trigger a partial denial of service to the Siebel Apps – Marketing component of Oracle Siebel CRM. The impact is limited to availability, as the attack can cause the application to become unavailable for certain users while other functions remain operational.

Affected Systems

The affected product is Oracle Siebel CRM – Siebel Apps – Marketing (the Email Marketing component) in versions 17.0 through 26.9. Only those installations running the specified versions are susceptible.

Risk and Exploitability

The CVSS score of 3.7 indicates low severity, with the attack vector and required conditions reflected by a network-based, high attack complexity, unauthenticated scenario. The EPSS score is not available, and the vulnerability is not listed in the CISA KEV catalog, suggesting a modest likelihood of exploitation. Because the impact is confined to service availability and requires no privileges, the overall risk is moderate for organizations that rely on uninterrupted marketing operations.
