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: 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: 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 11 Nov 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

1. Monitor Microsoft’s official channels for patches or updates addressing CVE-2025-62206 and apply them promptly once released. 2. Restrict network access to the on-premises Dynamics 365 servers by implementing strict firewall rules and network segmentation to limit exposure to untrusted networks. 3. Employ multi-factor authentication and robust access controls to reduce the risk of user interaction leading to exploitation. 4. Conduct user awareness training to educate employees about phishing and social engineering tactics that could trigger the vulnerability. 5. Implement comprehensive logging and monitoring of Dynamics 365 access and network traffic to detect unusual activities indicative of exploitation attempts. 6. Review and minimize the amount of sensitive data stored within Dynamics 365 where feasible, applying data classification and encryption at rest and in transit. 7. Consider deploying web application firewalls (WAFs) or intrusion detection/prevention systems (IDS/IPS) to detect and block suspicious network requests targeting Dynamics 365. 8. Regularly audit and update security configurations of the Dynamics 365 environment to adhere to best practices and reduce attack surface.

Description

Exposure of sensitive information to an unauthorized actor in Microsoft Dynamics 365 (on-premises) allows an unauthorized attacker to disclose information over a network.

Impact

For European organizations, the primary impact of CVE-2025-62206 is the unauthorized disclosure of sensitive information, which can include customer data, financial records, or proprietary business information managed within Microsoft Dynamics 365. This exposure risks violating data protection regulations such as the GDPR, potentially resulting in legal penalties and reputational damage. The vulnerability could be exploited by external attackers to gain insights into internal operations or confidential data without needing credentials, increasing the risk of targeted phishing or social engineering campaigns. While the vulnerability does not affect system integrity or availability, the confidentiality breach alone can have severe consequences, including loss of competitive advantage and erosion of customer trust. Organizations in regulated industries such as finance, healthcare, and government are particularly vulnerable due to the sensitivity of their data. The medium severity score suggests that while the threat is serious, it is not critical, but timely mitigation is essential to prevent exploitation. The lack of known exploits in the wild provides a window for proactive defense, but the ease of network-based exploitation without privileges means attackers could potentially leverage this vulnerability in targeted attacks.

The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
MITRE discourages mapping vulnerabilities to this broad entry; the root cause is usually a more specific weakness.
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.
