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: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.
Exploit Code Maturity: Unproven: No exploit code is available, or an exploit is theoretical.
Remediation Level: Official Fix: A complete vendor solution is available. Either the vendor has issued an official patch, or an upgrade is available.
Report Confidence: Confirmed: Detailed reports exist, or functional reproduction is possible (functional exploits may provide this). Source code is available to independently verify the assertions of the research, or the author or vendor of the affected code has confirmed the presence of the vulnerability.

Exploitation evidence

Disclosed: evidence found.
CVE published 8 Jul 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 2026-10-26.

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. Immediate prioritization of upgrading all Windows 10 Version 1507 systems to a supported and patched Windows version to eliminate exposure to this vulnerability. 2. Implement strict network segmentation to isolate legacy systems from sensitive network segments and limit potential data leakage paths. 3. Deploy network monitoring tools capable of detecting anomalous data flows related to GDI or unusual graphical data transmissions over the network. 4. Use endpoint detection and response (EDR) solutions to identify suspicious processes interacting with the GDI subsystem. 5. Restrict network access to legacy systems using firewalls and access control lists (ACLs), allowing only trusted hosts and services. 6. Conduct a thorough asset inventory to identify all systems running Windows 10 Version 1507 and prioritize their remediation. 7. Educate IT staff about the vulnerability and encourage vigilance for unusual network activity or signs of information leakage. 8. Once available, promptly apply official patches or security updates from Microsoft. 9. Consider deploying application whitelisting to prevent unauthorized code execution that might exploit the vulnerability. 10. Review and enhance data encryption practices to protect sensitive information even if disclosed.

Description

Protection mechanism failure in Windows GDI allows an unauthorized attacker to disclose information over a network.

Impact

For European organizations, the primary impact of CVE-2025-47984 is the unauthorized disclosure of sensitive information, which could include confidential graphical data or memory contents processed by the GDI. This breach of confidentiality could facilitate further attacks such as social engineering, credential theft, or targeted espionage. Organizations in sectors like government, finance, healthcare, and critical infrastructure that rely on legacy Windows 10 Version 1507 systems are particularly vulnerable. The lack of required privileges or user interaction lowers the barrier for attackers, increasing the risk of widespread exploitation if the vulnerability is weaponized. Although the vulnerability does not affect system integrity or availability, the exposure of sensitive data can lead to regulatory non-compliance under GDPR and damage organizational reputation. The absence of known exploits currently provides a window for proactive mitigation, but the high CVSS score (7.5) and network attack vector necessitate urgent attention. The impact is exacerbated in environments where network segmentation is weak and legacy systems are interconnected with critical assets.
