MITRE ATT&CK
2 techniques across 2 tactics: Collection, Discovery The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | No authentication is required (CVSS PR:N) and no user interaction is needed (UI:N), confirming this is a remotely exploitable, unauthenticated flaw against any network-accessible Siebel 25.0-25.5 deployment. Attack complexity is low (AC:L), indicating no race condition or special precondition is described. The primary limiting factor is product version: only Siebel CRM versions 25.0-25.5 are confirmed vulnerable. Deployments on earlier version lines or those not yet upgraded to the 25.x release series are not confirmed affected. The scope is contained (S:U), so exploitation does not pivot to other system components. |
| Impact | The CVSS 3.1 vector AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N reflects a low-complexity, unauthenticated network attack with confidentiality impact limited to a partial data subset - no integrity or availability degradation is claimed. Real-world risk is moderate but not urgent: the scope is bounded (C:L, not C:H), no public exploit code exists, and CISA KEV does not list this CVE. EPSS data was not provided, but the combination of missing POC and low-impact scope suggests a below-average exploitation probability in the near term. Even a mid-sized municipal IT team in inowroclaw running Siebel CRM in a public-facing configuration should treat this as a prompt but non-emergency patch cycle rather than a crisis response, given that the data exposure is constrained to what the authenticated user layer would normally see. Deployments where the Siebel web tier is exposed directly to the internet or untrusted networks represent the highest-risk posture; internal-only deployments face materially lower exposure. |
| Exploit ScenarioDerived | An unauthenticated attacker with HTTP access to the Siebel CRM web tier sends a crafted request to the vulnerable User Interface endpoint, causing the application to return data that should require authorization to view. No credentials, special tooling, or user interaction are required. No public proof-of-concept has been identified at time of analysis, so exploitation is likely opportunistic rather than scripted. |

Alert meAnalysisAIv1 – Sep 02, 2026
Unauthenticated information disclosure in Oracle Siebel CRM's End User User Interface component allows remote attackers to read a subset of CRM data over HTTP without credentials. Versions 25.0 through 25.5 are confirmed affected. Oracle has released a fix in the July 2025 Critical Patch Update; no public exploit or active exploitation has been identified at time of analysis.
RemediationAI
Apply the Oracle Critical Patch Update for July 2025, available at https://www.oracle.com/security-alerts/cpujul2025.html. Oracle does not publish granular patch version numbers outside the CPU documentation, so consult the advisory for the exact patch identifier and installation instructions applicable to your Siebel 25.x environment. As a compensating control where immediate patching is not feasible, restricting network access to the Siebel web tier - via firewall rules or reverse-proxy ACLs - to authenticated, trusted network segments will reduce exposure, at the cost of limiting legitimate remote end-user access. No workaround is described in the advisory beyond applying the patch.

Technical ContextAI · show details
Oracle Siebel CRM is a large-scale enterprise customer relationship management platform with a web-based User Interface layer that serves end-user-facing functionality over HTTP. The affected component falls under CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor), indicating that the UI layer surfaces or transmits accessible data without enforcing proper authorization checks on that data path. The CPE string cpe:2.3:a:oracle:siebel_crm:*:*:*:*:*:*:*:* covers the full Siebel CRM application product line; affected versions are narrowed to 25.0-25.5 per the Oracle CPU advisory. The vulnerability is reachable over standard HTTP, meaning it requires no special protocol or network position beyond TCP connectivity to the Siebel web tier.
