CVE-2026-21924VulnerabilityPublished 20 Jan 2026

CVE-2026-21924: Easily exploitable vulnerability allows low privileged attacker with network access via HTTP to compromise Oracle Utilities Application Framework. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Utilities Application Framework, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Utilities Application Framework accessible data as well as unauthorized read access to a subset of Oracle Utilities Application Framework accessible data.

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: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
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: 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.

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

1. Apply official Oracle patches and updates as soon as they become available to address CVE-2026-21924. 2. Restrict network access to Oracle Utilities Application Framework interfaces, limiting exposure to trusted internal networks and VPNs only. 3. Implement strict access controls and least privilege principles to minimize the privileges of users interacting with the framework. 4. Conduct targeted user awareness training focusing on social engineering and phishing risks to reduce the likelihood of successful user interaction exploitation. 5. Monitor logs and network traffic for unusual activities related to Oracle Utilities Application Framework, including unauthorized data modification attempts. 6. Employ multi-factor authentication (MFA) for all users accessing the framework to add an additional security layer. 7. Segment the network to isolate critical utility management systems from general corporate networks. 8. Regularly audit and review user permissions and data access patterns within the framework to detect anomalies early. 9. Collaborate with Oracle support and security advisories to stay informed about emerging threats and mitigation strategies related to this vulnerability. 10. Develop and test incident response plans specifically addressing potential exploitation scenarios of this vulnerability.

Description

CVE-2026-21924 is a medium severity vulnerability in Oracle Utilities Application Framework versions 4.4.0.3.0 through 25.10. It allows a low privileged attacker with network access via HTTP to perform unauthorized read and write operations on accessible data. Exploitation requires user interaction from a person other than the attacker, and successful attacks can impact additional products beyond the framework itself. The vulnerability affects confidentiality and integrity but not availability, with a CVSS 3.1 base score of 5.

Impact

For European organizations, especially those in the utilities sector, this vulnerability poses a risk of unauthorized data manipulation and disclosure. Utilities often manage critical infrastructure such as electricity, water, and gas distribution, making data integrity and confidentiality paramount. Exploitation could lead to unauthorized changes in operational data, potentially disrupting service management or causing incorrect billing and reporting. Unauthorized read access could expose sensitive customer or operational data, leading to privacy violations and regulatory non-compliance under GDPR. The requirement for user interaction increases the risk of targeted social engineering attacks against employees or contractors. Given the interconnected nature of utility systems, a successful attack may cascade to other integrated Oracle products, amplifying the impact. While availability is not directly affected, the compromise of data integrity and confidentiality can undermine trust and operational reliability. European utilities are increasingly targeted by cyber adversaries, making timely mitigation critical to prevent potential espionage, sabotage, or fraud.
