CVE-2023-6672: Stored XSS in National Keep's CyberMath
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in National Keep Cyber Security Services CyberMath allows Stored XSS.
This issue affects CyberMath: from v1.4 before v1.5.
Security readout for executives and security teams
Plain-English summary
CyberMath v1.4 has a stored cross-site scripting flaw. An authenticated user could save malicious content that later runs in another user’s browser when viewed. Business impact is mainly limited data exposure or unauthorized actions in the application context, not system takeover based on the published CVSS.
Executive priority
Treat as a normal-priority application security update unless CyberMath is internet-facing or used by many untrusted users. The issue can affect user trust and session integrity, but published severity is moderate and no active exploitation is cited.
Technical view
CVE-2023-6672 is CWE-79 stored XSS in National Keep Cyber Security Services CyberMath from v1.4 before v1.5. CVSS 3.1 is 5.4: network reachable, low complexity, low privileges required, user interaction required, changed scope, low confidentiality and integrity impact, no availability impact.
Likely exposure
Exposure is limited to organizations running CyberMath v1.4 or versions in the v1.4-to-before-v1.5 range. The vulnerable surface is the CyberMath web application where authenticated users can submit content later rendered to other users.
Exploitation context
The source bundle does not report active exploitation, and CISA KEV status is false. Exploitation would require a low-privileged authenticated user and a victim user to view affected stored content. No public exploit status is provided in the cited sources.
Researcher notes
The record is sparse: it identifies stored XSS, affected range, and CVSS only. Do not assume affected endpoints or payload behavior from the CVE text. One listed USOM URL is marked broken in the bundle; use the available Turkish cybersecurity advisory and CVE records for confirmation.
Mitigation direction
Identify any deployed CyberMath instances and versions.
Upgrade CyberMath affected versions to v1.5 or later, per the affected-version boundary.
Review the Turkish government advisory for vendor-specific guidance.
If upgrade is delayed, restrict untrusted user access where operationally feasible.
Validation and detection
Confirm CyberMath version is not v1.4 or before v1.5.
Review application logs for suspicious stored content changes by low-privileged users.
Verify input/output handling changes after applying the vendor update.
Check vendor or government advisory pages for any revised remediation details.

Client-side and session-facing weaknesses should be reviewed alongside initial-access and user-execution behaviors. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.
