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

Attack Vector: Local: The vulnerable component is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either: the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or remotely (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., tricking a legitimate user into opening a malicious document).
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: 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 10 Jun 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

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 2026-10-25.

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

To mitigate CVE-2025-33060, organizations should prioritize upgrading from Windows 10 Version 1507 to a supported and fully patched Windows version, as this legacy build is no longer maintained and lacks security updates. Until an official patch is released by Microsoft, restrict local access to affected systems by enforcing strict access controls and limiting user privileges to the minimum necessary. Employ endpoint protection solutions that monitor for unusual local activity or memory access patterns. Conduct regular audits of user accounts and remove or disable unnecessary accounts with local access rights. Use application whitelisting and system hardening to reduce the attack surface. Additionally, implement memory protection technologies such as Data Execution Prevention (DEP) and Address Space Layout Randomization (ASLR) where possible to hinder exploitation of memory vulnerabilities. Monitor security advisories from Microsoft for the release of patches or workarounds and apply them promptly. Finally, educate users about the risks of unauthorized local access and enforce policies to prevent physical or remote local access by untrusted individuals.

Description

Out-of-bounds read in Windows Storage Management Provider allows an authorized attacker to disclose information locally.

Impact

The primary impact of CVE-2025-33060 is unauthorized disclosure of sensitive information due to an out-of-bounds read vulnerability. Although the attacker must have authorized local access with limited privileges, the ability to read memory beyond intended boundaries can expose confidential data such as credentials, encryption keys, or other sensitive information residing in memory. This can facilitate further attacks like privilege escalation or lateral movement if attackers gain additional intelligence. The vulnerability does not affect system integrity or availability, so it does not cause crashes or data corruption. The limited attack vector (local access required) reduces the risk of widespread exploitation, but organizations with legacy Windows 10 Version 1507 deployments remain at risk. The absence of known exploits in the wild currently lowers immediate threat levels, but the medium CVSS score indicates a meaningful confidentiality risk. Enterprises relying on this outdated Windows version, especially in environments with multiple users or shared access, could face data leakage risks. This vulnerability underscores the importance of maintaining up-to-date systems to minimize exposure to such memory safety issues.

The product reads data past the end, or before the beginning, of the intended buffer.
Implementation · Input Validation
Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
