CVE Alert: CVE-2025-11030 – Tutorials-Website – Employee Management System

Risk verdict

High risk: remote, unauthenticated access to a privileged admin function with publicly disclosed exploitation potential could enable data disclosure or manipulation.

Why this matters

The flaw directly enables improper authorization on a key HR control, risking exposure or alteration of all-applied-leave records. In organisations relying on this EMS, attackers could undermine payroll, leave balances, and compliance, with automation making rapid, widespread abuse feasible.

Most likely attack path

An attacker can target the HTTP endpoint /admin/all-applied-leave.php over the network (AV:N, no user interaction required). With PR:N and UI:N, exploitation can occur without credentials, potentially tampering or exfiltrating leave data and extending impact within the same security domain (SC:N, SI:N, SA:N). The combination of remote access and privilege bypass raises the likelihood of rapid data manipulation.

Who is most exposed

Public-facing or internet-accessible EMS deployments, especially those exposing admin endpoints or using rolling release systems, are at greatest risk. Small-to-medium organisations in education, services, or SMB sectors commonly run these apps with limited hardening.

Detection ideas

• Anomalous or repetitive requests to /admin/all-applied-leave.php lacking authentication headers.
• Data modifications or reads to leave records outside normal admin workflows.
• Unexpected parameter tampering or unusual payloads in that endpoint.
• Spike in traffic to the admin path, especially from diverse IPs.
• IOCs from related advisories, e.g., exploit signatures or atypical admin activity patterns.

Mitigation and prioritisation

• Apply vendor patch or upgrade to fixed release; if unavailable, implement strict access controls for the endpoint (VPN/SSO) and require authentication with least privilege.
• Implement deny-by-default for admin paths; add strong input validation and server-side authorization checks.
• Deploy WAF rules to block common tampering attempts and monitor for abnormal admin activity.
• Enable comprehensive logging, alert on anomalous data changes, and perform regular integrity checks of leave data.
• If KEV is present or EPSS ≥ 0.5, treat as priority 1. Otherwise, prioritise based on exposure and likelihood of automated exploitation.
