Mitigating Controls (NIST 800-53 r5)AI
SI-10 requires validation of all information inputs, directly addressing the improper neutralization of input that enables this XSS vulnerability.
SI-15 mandates filtering of information prior to output on web pages, preventing the execution of injected scripts in this web page generation flaw.
SI-2 ensures timely identification, reporting, and correction of flaws like this specific XSS vulnerability via patching as advised by Microsoft.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
XSS vulnerability in public-facing web application (Dynamics 365 Field Service online) directly enables remote exploitation for initial access or privilege escalation via T1190: Exploit Public-Facing Application.
NVD Description
Improper neutralization of input during web page generation ('cross-site scripting') in Dynamics 365 Field Service (online) allows an authorized attacker to perform spoofing over a network.
Deeper analysisAI
CVE-2025-62210 is a cross-site scripting (XSS) vulnerability stemming from improper neutralization of input during web page generation, mapped to CWE-79. It affects Dynamics 365 Field Service (online). Published on 2025-11-11T18:15:48.273, the vulnerability carries a CVSS v3.1 base score of 8.7 (AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:N), indicating high severity due to network accessibility, low attack complexity, and significant confidentiality and integrity impacts.
An authorized attacker with low privileges (PR:L) can exploit this flaw over the network (AV:N) by tricking a user into performing an action (UI:R), such as interacting with a maliciously crafted web page. Exploitation enables spoofing attacks with a changed scope (S:C), potentially compromising high levels of confidentiality and integrity for affected users.
