CVE-2025-11959 Overview
CVE-2025-11959 is an information disclosure vulnerability in Premierturk Information Technologies Inc. Excavation Management Information System. The flaw exposes files and directories to external parties and leaks private personal information to unauthorized actors. Authenticated attackers with low privileges can perform footprinting and abuse application functionality over the network. The issue affects all versions prior to v.10.2025.01. The vulnerability is classified under [CWE-359: Exposure of Private Personal Information to an Unauthorized Actor].
Critical Impact
Authenticated network attackers can access restricted files and harvest personally identifiable information (PII) without user interaction, enabling reconnaissance and large-scale data exposure.
Affected Products
- Premierturk Excavation Management Information System versions before v.10.2025.01

Technical Details for CVE-2025-11959
Vulnerability Analysis
The Excavation Management Information System fails to enforce access controls on files, directories, and personal data records. An authenticated user with low privileges can request resources outside their authorization scope. The application returns sensitive content including private personal information belonging to other users or system tenants. The flaw enables both passive footprinting and active functionality misuse, where built-in features are repurposed to retrieve data the caller should not access.
Root Cause
The root cause is missing or improperly enforced authorization checks on data retrieval endpoints. The application trusts client-supplied identifiers and serves files or PII records without validating that the requester owns or may access the resource. This pattern aligns with [CWE-359] exposure of private personal information.
Attack Vector
Exploitation requires network access and a valid low-privileged account. No user interaction is required. An attacker authenticates to the application, then iterates over predictable resource identifiers or invokes legitimate functions with manipulated parameters. The server responds with files, directory listings, and PII intended for other users. The vulnerability impacts both confidentiality and integrity of stored records.
No verified public proof-of-concept code is available. See the USOM Security Notification TR-25-0388 for the official advisory.
Detection Methods for CVE-2025-11959
Indicators of Compromise
- Unusual sequential requests to file or record retrieval endpoints from a single authenticated session
- Large volumes of HTTP 200 responses returning PII fields to a single user account
- Access patterns where one user account retrieves records associated with many distinct tenants or owners
- Outbound transfers of bulk data following normal authentication events
Detection Strategies
- Review application access logs for authenticated users requesting object identifiers outside their normal scope
- Correlate authentication events with download volume per session to identify scraping behavior
- Implement runtime authorization checks and alert when a user accesses records owned by another principal
- Baseline normal per-user data access rates and flag deviations
Monitoring Recommendations
- Enable verbose audit logging on all file and personal data retrieval endpoints
- Forward web server and application logs to a centralized SIEM for correlation
- Monitor for enumeration patterns such as incremental ID requests within short time windows
- Track failed and successful authorization decisions separately to surface broken access control
How to Mitigate CVE-2025-11959
Immediate Actions Required
- Upgrade Excavation Management Information System to v.10.2025.01 or later without delay
- Audit existing user accounts and revoke unnecessary low-privileged access
- Review application logs from the past 90 days for signs of unauthorized data retrieval
- Notify affected data subjects if evidence of PII exposure is found, per applicable regulations
Patch Information
Premierturk Information Technologies Inc. addresses the vulnerability in Excavation Management Information System v.10.2025.01. Apply the vendor update to remediate the access control and information exposure defects. Refer to the USOM Security Notification TR-25-0388 for vendor coordination details.
Workarounds
- Restrict network access to the application using firewall rules or VPN-only access until the patch is applied
- Disable or limit accounts that do not require active access to reduce the authenticated attack surface
- Apply web application firewall (WAF) rules to block enumeration patterns against object identifiers
- Increase logging verbosity and review access events daily until remediation completes
# Example WAF rate-limit rule to slow enumeration of resource identifiers
# (adapt to your WAF syntax; this is illustrative)
