CVE Alert: CVE-2025-11151 – Beyaz Bilgisayar Software Design Industry and Trade Ltd. Co. – CityPLus

Risk verdict

High risk: remote unauthenticated disclosure of sensitive information via unpublicized CityPLus pages; exploitation requires no user interaction.

Why this matters

Attackers can enumerate hidden resources and extract sensitive data, enabling targeted exfiltration or credential harvesting. For organisations using CityPLus, the vulnerability threatens regulatory compliance, reputational damage, and potential service exposure.

Most likely attack path

External actors scan internet-facing CityPLus endpoints for undocumented pages; no credentials and low attack complexity enable discovery. Successful hits reveal confidential data or internal structure hints, supporting further intrusion or data theft.

Who is most exposed

Deployments with internet-facing CityPLus web interfaces are most at risk, especially on-prem or cloud-hosted instances and multi-tenant setups where misconfigurations expose internal pages.

Detection ideas

• Probes targeting non-documented endpoints from distributed sources.
• Unexpected 200 OK responses or verbose error messages for unknown pages.
• Logs showing access to internal paths or leakage of server/version details.
• Spikes in unauthenticated GET requests to sensitive areas.
• WAF/IDS alerts for information-disclosure patterns or directory listing attempts.

Mitigation and prioritisation

• Patch to V24.29500.1.0 or newer immediately.
• Disable directory listing; remove exposure of internal pages; enforce authentication/least privilege.
• Tighten access controls (MFA, IP allowlists for admin endpoints).
• Harden error handling; ensure responses do not reveal sensitive data.
• Validate fixes in staging before production; monitor logs post-patch.
