CVE-2024-7107 Overview
CVE-2024-7107 is an information disclosure vulnerability in National Keep Cyber Security Services CyberMath. The flaw is classified under [CWE-552] as Files or Directories Accessible to External Parties. Authenticated local actors can collect data from common resource locations that should not be reachable. The issue affects all CyberMath versions prior to CYBM.240816253. Turkey's national cyber security authority USOM published advisory TR-24-1549 documenting the issue.
Critical Impact
A low-privileged local user can read sensitive files from common resource locations within the CyberMath application, exposing confidential data without triggering integrity or availability changes.
Affected Products
- National Keep Cyber Security Services CyberMath (all versions before CYBM.240816253)
- Deployments exposing local file resources to authenticated users
- Environments where CyberMath stores sensitive configuration or user data on the host

Technical Details for CVE-2024-7107
Vulnerability Analysis
The vulnerability lets local, authenticated users access files and directories that CyberMath stores in predictable, common resource locations. Because access controls do not restrict these paths to their intended consumers, an attacker with basic application privileges can enumerate and read sensitive content. The result is confidentiality loss without any impact to integrity or availability. Exploitation is straightforward and requires no user interaction beyond normal authenticated access to the host.
Root Cause
The root cause is missing or insufficient access control on files and directories placed in predictable locations, tracked as [CWE-552]. CyberMath does not enforce a boundary that prevents unauthorized principals from opening these resources. Attackers benefit from location predictability, since well-known paths under the application directory allow direct requests without discovery effort.
Attack Vector
The attack vector is local. An attacker needs low-privileged access to the system hosting CyberMath, then queries the common resource locations exposed by the application. No specialized tooling is required. The vulnerability supports data collection consistent with MITRE ATT&CK technique T1552.001 (Credentials In Files) and T1005 (Data from Local System), depending on the content stored in the exposed paths.
No public proof-of-concept exploit is listed in Exploit-DB, and the vulnerability is not tracked in the CISA Known Exploited Vulnerabilities catalog. Refer to the USOM Notification TR-24-1549 and the Siber Güvenlik Advisory TR-24-1549 for vendor guidance.
Detection Methods for CVE-2024-7107
Indicators of Compromise
- Unexpected read access from low-privileged accounts to CyberMath application directories and resource folders
- File access telemetry showing enumeration of configuration, log, or backup files under known CyberMath paths
- Outbound data transfers immediately following local reads of CyberMath resource locations
Detection Strategies
- Monitor file system audit logs for read operations against CyberMath resource directories by non-service accounts
- Baseline normal CyberMath file access patterns and alert on deviations, especially bulk reads by interactive users
- Correlate local authentication events with subsequent access to sensitive application directories
Monitoring Recommendations
- Enable object access auditing on the host filesystem for the CyberMath installation directory
- Ship endpoint file access telemetry to a central data lake for retention and correlation
- Alert when the same low-privileged user reads multiple files across CyberMath common resource locations within a short window
How to Mitigate CVE-2024-7107
Immediate Actions Required
- Upgrade CyberMath to version CYBM.240816253 or later on all hosts
- Inventory user accounts with local access to CyberMath systems and remove unnecessary privileges
- Review CyberMath resource directories and remove sensitive files that do not need to reside on disk
Patch Information
The vendor has released a fixed build. Upgrade CyberMath to version CYBM.240816253 or later, which addresses the file exposure. Consult the USOM Notification TR-24-1549 and the Siber Güvenlik Advisory TR-24-1549 for the official fix details and any deployment notes.
Workarounds
- Restrict filesystem permissions on CyberMath common resource locations to the application service account only
- Limit local logon rights to the CyberMath host to administrators and required operators
- Encrypt sensitive files at rest so that unauthorized reads do not expose plaintext content
