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: High: A successful attack depends on conditions beyond the attacker's control. That is, a successful attack cannot be accomplished at will, but requires the attacker to invest in some measurable amount of effort in preparation or execution against the vulnerable component before a successful attack can be expected. For example, a successful attack may require an attacker to: gather knowledge about the environment in which the vulnerable target/component exists; prepare the target environment to improve exploit reliability; or inject themselves into the logical network path between the target and the resource requested by the victim in order to read and/or modify network communications (e.g., a man in the middle attack).
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: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
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.

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.

What to do

AI-suggested

1. Upgrade affected Oracle Java SE and GraalVM Enterprise Edition versions to the latest patched releases once available from Oracle, as this is the most effective mitigation. 2. Where upgrading is not immediately possible, disable or restrict the use of Java Web Start applications and Java applets that load untrusted code, especially from internet sources. 3. Implement strict application whitelisting and sandboxing policies to prevent execution of untrusted Java code in client environments. 4. Educate users about the risks of interacting with untrusted Java applications or links requiring Java execution, emphasizing the need to avoid clicking suspicious links or running unknown Java content. 5. Monitor network traffic and endpoint behavior for unusual activity related to Java runtime environments, focusing on attempts to load or execute untrusted code. 6. For server environments, ensure only trusted code is deployed and executed, maintaining strict code signing and deployment policies. 7. Review and tighten firewall and network segmentation controls to limit unnecessary network access to client machines running vulnerable Java versions. 8. Consider phasing out legacy Java client technologies like Java Web Start and applets in favor of modern, more secure application delivery methods.

Description

Vulnerability in the Oracle Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: JavaFX). Supported versions that are affected are Oracle Java SE: 8u391; Oracle GraalVM Enterprise Edition: 20.3.12 and 21.3.8. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE, Oracle GraalVM Enterprise Edition. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Java SE, Oracle GraalVM Enterprise Edition accessible data. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability does not apply to Java deployments, typically in servers, that load and run only trusted code (e.g., code installed by an administrator). CVSS 3.1 Base Score 3.1 (Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:L/A:N).

Impact

For European organizations, the impact of CVE-2024-20925 is generally low but context-dependent. Organizations that still use Oracle Java SE 8u391 or affected GraalVM versions in client environments running sandboxed Java Web Start applications or applets that load untrusted code are at risk of unauthorized data modification within those Java runtimes. This could lead to integrity issues in client-side applications, potentially affecting local data or application behavior. However, since the vulnerability requires user interaction and is difficult to exploit, the risk of widespread compromise is limited. Server-side environments, which are more common in enterprise deployments, are not affected if they only run trusted code. The vulnerability does not impact confidentiality or availability, reducing the severity of potential damage. Nonetheless, organizations relying on legacy Java client technologies should assess exposure, especially in sectors where Java applets or Web Start are still in use, such as financial services, manufacturing, or government agencies with legacy systems. The absence of known exploits reduces immediate threat but does not eliminate the need for vigilance.
