Vulnerability in the Siebel CRM End User product of Oracle Siebel CRM (component: Reports). Supported versions that are affected are 17.0-26.7. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Siebel CRM End User. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Siebel CRM End User accessible data. CVSS 3.1 Base Score 7.5 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N).
AnalysisAI
Unauthenticated remote attackers with HTTP access to the Reports component of Oracle Siebel CRM End User (versions 17.0 through 26.7) can bypass intended access controls and read data they should not be able to reach, giving them unauthorized access to critical data or the full set of data accessible to the Siebel CRM End User application. The flaw carries a CVSS 3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N, confidentiality-only impact), meaning it is trivially reachable and requires no credentials or user interaction, but it does not permit data modification or denial of service. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires network reachability to the Siebel CRM End User Reports HTTP endpoint, and per the CVSS vector (PR:N/UI:N) no authentication and no user interaction are needed, so the conditions are limited to exposure of the Reports component rather than any credential or configuration prerequisite stated in the description. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/C:H/I:N/A:N, 7.5) describes a low-skill, remotely reachable information-disclosure flaw: no authentication, no user interaction, no complexity, and high confidentiality impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the Oracle fix published in the referenced security alert (https://www.oracle.com/security-alerts/cspusep2026.html); Oracle ships Siebel fixes through its Critical Security Patch Update cycle, and the input does not state a discrete patch version number, so treat this as patch available per vendor advisory and confirm the exact bundle with Oracle Support before upgrading. … Detailed patch versions, workarounds, and compensating controls in full report. |
