Security readout for executives and security teams
Plain-English summary
CVE-2025-11151 is a high-severity information disclosure issue in Beyaz Bilgisayar CityPLus before V24.29500.1.0. An unauthenticated remote actor may detect non-public web pages and expose sensitive system information. This can support reconnaissance and follow-on attacks, even though availability impact is not reported.
Executive priority
Treat as a near-term remediation priority for any internet-facing CityPLus deployment. The business risk is disclosure of sensitive pages or system information that could enable broader compromise. No confirmed active exploitation is cited, but the unauthenticated remote attack profile raises urgency.
Technical view
The CVE maps to CWE-200 and CWE-497. CVSS 3.1 is 8.2: network exploitable, low complexity, no privileges, no user interaction, with high confidentiality and low integrity impact. The affected product is CityPLus before V24.29500.1.0. Public sources do not provide exploit details or confirm exploitation.
Likely exposure
Highest concern is externally reachable CityPLus deployments running versions before V24.29500.1.0. Internal-only deployments still matter if attackers gain network access. Organizations not using CityPLus are not exposed based on current sources.
Exploitation context
Sources describe unauthorized detection of unpublicized web pages and sensitive system information exposure. CISA KEV is not indicated, and the provided sources do not state active exploitation. The vulnerability is still urgent because it is unauthenticated, remote, and low complexity.
Researcher notes
Evidence is limited to the CVE record and Turkish government advisory references. The affected boundary is CityPLus before V24.29500.1.0. No public exploit, patch notes, or technical root-cause details are included in the provided sources. Avoid assuming impact beyond information disclosure and limited integrity impact.
Mitigation direction
- Identify all CityPLus deployments and owners.
- Prioritize externally reachable CityPLus systems.
- Upgrade CityPLus instances below V24.29500.1.0 where an update is available.
- Check Beyaz Bilgisayar or government advisory guidance for exact remediation instructions.
- Restrict network access to CityPLus until remediation is complete.
- Review exposed non-public pages and remove unnecessary sensitive information.
Validation and detection
- Confirm installed CityPLus version on each instance.
- Verify no instance remains below V24.29500.1.0.
- Confirm internet-facing exposure through asset inventory or external attack-surface tools.
- Review web access logs for unusual discovery of non-public pages.
- Document compensating controls if immediate upgrade is not possible.
