Attack Vector: Network
Attack Complexity: Low
Privileges Required: None

Scope: Unchanged
Confidentiality: Low
Integrity: None
Availability: None

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

CVE published 15 Jul 2025
Detectable: no evidence on record.
No public nuclei template indexed

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-25.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

European organizations should immediately assess their deployment of Siebel CRM End User versions 25.0 through 25.5 to determine exposure. Since no patches are currently linked, organizations should implement compensating controls such as restricting network access to the Siebel CRM End User interface to trusted internal networks only, using network segmentation and firewall rules to block unauthorized HTTP access. Employing Web Application Firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the User Interface component can reduce risk. Monitoring network traffic and application logs for unusual access patterns or unauthorized data retrieval attempts is critical. Organizations should also review and tighten access controls and authentication mechanisms around the CRM environment, even though this vulnerability does not require authentication, to reduce overall attack surface. Preparing for rapid deployment of patches or updates from Oracle once available is essential. Additionally, conducting security awareness and incident response exercises focused on data exposure scenarios can improve readiness. Finally, organizations should verify compliance with GDPR and other relevant data protection laws by documenting risk assessments and mitigation efforts related to this vulnerability.

Description

Vulnerability in the Siebel CRM End User product of Oracle Siebel CRM (component: User Interface). Supported versions that are affected are 25.0-25.5. 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 read access to a subset of Siebel CRM End User accessible data. CVSS 3.1 Base Score 5.3 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N).

Impact

For European organizations using Oracle Siebel CRM End User versions 25.0 to 25.5, this vulnerability poses a risk of unauthorized disclosure of sensitive CRM data. Since Siebel CRM is widely used in sectors such as finance, telecommunications, manufacturing, and government services across Europe, unauthorized data exposure could lead to breaches of GDPR and other data protection regulations, resulting in legal penalties and reputational damage. The unauthorized read access could expose customer personal information, business intelligence, or other confidential data, undermining trust and potentially facilitating further targeted attacks. Although the vulnerability does not allow data modification or service disruption, the confidentiality breach alone is significant, especially for organizations handling sensitive or regulated data. The ease of exploitation without authentication or user interaction increases the risk, particularly if the Siebel CRM End User interface is exposed to untrusted networks or insufficiently segmented internal networks. The absence of known exploits currently reduces immediate risk, but the medium severity and ease of exploitation warrant prompt attention.

Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
