Deeper analysis
Microsoft Dynamics 365 (On-Premises) contains an information disclosure vulnerability tracked as CVE-2024-35263. The flaw is rated 5.7 under CVSS 3.1 with the vector AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:N/A:N and is associated with CWE-200. It affects the on-premises deployment of the Dynamics 365 platform and permits exposure of sensitive data without requiring elevated privileges beyond a standard authenticated account.
An attacker with low-privileged network access can trigger the issue by sending a crafted request that elicits confidential information from the server. User interaction is required on the part of the victim, after which the attacker obtains high-confidentiality data while integrity and availability remain unaffected.
Microsoft has published an advisory describing the vulnerability and associated updates at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2024-35263. The EPSS score has remained flat at 0.0556 since disclosure, indicating no material increase in observed exploitation interest.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Automated marking applies security attributes to system outputs, making it harder for attackers to exploit unmarked sensitive information leading to unauthorized exposure.
Proper attribute retention and permitted-value enforcement limits unauthorized actors from accessing sensitive information lacking correct labels.
Prevents unauthorized exposure of sensitive information by prohibiting untrusted external systems from processing or storing it.
By enforcing authorization matching prior to sharing, the control reduces the risk of exposing sensitive information to unauthorized actors.
Review and removal of nonpublic information from publicly accessible systems directly prevents exposure of sensitive data to unauthorized actors.
Data mining protection mechanisms detect and block unauthorized bulk extraction of sensitive data, directly mitigating exposure to unauthorized actors.
Literacy training teaches users to recognize and avoid actions that result in unauthorized exposure of sensitive information.
Retaining and monitoring training records confirms personnel have completed privacy and security awareness training on handling sensitive data, reducing the chance of unauthorized exposure due to lack of knowledge.
