Integrity: Low
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: High: The attacker is authorized with (i.e., requires) privileges that provide significant (e.g., administrative) control over the vulnerable component that could affect component-wide settings and files.
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: None: There is no loss of confidentiality within the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 21 Oct 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

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 26 Oct 2026.

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 or the CVSS exploit maturity 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

Enforce strict access controls and monitoring on DBA accounts to prevent unauthorized access or misuse.
Implement multi-factor authentication (MFA) for all privileged database users to reduce the risk of credential compromise.
Monitor audit logs and database activity for unusual modifications or access patterns that could indicate exploitation attempts.
Use database activity monitoring (DAM) tools to detect and alert on unauthorized changes to audit data in real time.
Restrict network access to Oracle Net services to trusted hosts and networks only, using firewalls and network segmentation.
Regularly review and rotate privileged credentials and ensure least privilege principles are applied.
Prepare to apply vendor patches promptly once available; subscribe to Oracle security advisories for updates.
Consider implementing immutable or write-once audit storage solutions to protect audit data integrity.
Conduct periodic security audits and penetration tests focusing on privileged access and audit mechanisms.
Educate database administrators and security teams about the risks associated with audit data tampering and the importance of safeguarding privileged accounts.

Description

Vulnerability in the Unified Audit component of Oracle Database Server. Supported versions that are affected are 23.4-23.9. Easily exploitable vulnerability allows high privileged attacker having DBA privilege with network access via Oracle Net to compromise Unified Audit. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Unified Audit accessible data. CVSS 3.1 Base Score 2.7 (Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:L/A:N).

Impact

For European organizations, the primary impact of CVE-2025-61749 lies in the potential compromise of audit data integrity within Oracle Database environments. Audit logs are essential for regulatory compliance (e.g., GDPR, NIS Directive), internal security monitoring, and forensic investigations. Unauthorized modification of audit records could lead to undetected malicious activities, hinder incident response, and result in non-compliance penalties. Since the vulnerability requires DBA privileges, the risk is heightened if privileged accounts are compromised or mismanaged. Organizations relying heavily on Oracle Database for critical applications, especially in regulated sectors such as finance, healthcare, and government, may face increased risks of audit tampering. Although the CVSS score is low, the strategic importance of audit data means that even limited integrity impacts can have significant operational and legal consequences. The lack of known exploits reduces immediate risk but does not eliminate the threat, especially from insider attackers or advanced persistent threats targeting privileged credentials.

Pillar weaknessCWE Top 25 (2025): #19OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.
MITRE discourages mapping vulnerabilities to this broad entry; the root cause is usually a more specific weakness.
Architecture and Design · Operation
Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
Architecture and Design · Separation of Privilege
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.
