Exploitation Conditions

No special conditions - remote unauthenticated exploitation against default configurations of Online Appointment Booking System 1.0.

Impact

CVSS 4.0 indicates low impact (VC:L/VI:L/VA:L) with network attack vector, no privileges, and no user interaction. EPSS score of 0.04% suggests low likelihood of widespread exploitation. No CISA KEV listing and the product's niche open-source nature point to minimal real-world risk. While the vulnerability is easily triggerable with a public proof-of-concept, the low impact and limited deployment make it a low-priority issue for most organizations. There is no contradiction between the CVSS severity and EPSS; the low impact reduces overall urgency despite easy exploitation.

Exploit ScenarioDerived

An unauthenticated remote attacker sends a crafted HTTP request to /admin/deletemanagerclinic.php with a malicious SQL payload in the 'clinic' parameter, exploiting the injection to extract sensitive data from the database, modify records, or cause denial of service. A publicly available exploit simplifies this attack.

AnalysisAIv1 – Jul 27, 2026

SQL injection in code-projects Online Appointment Booking System 1.0 allows remote attackers to manipulate the 'clinic' parameter in /admin/deletemanagerclinic.php, leading to unauthorized data access, modification, or deletion. A public exploit is available, though no active exploitation has been confirmed (not in CISA KEV), and EPSS indicates low (0.04%) exploitation probability.

RemediationAI

No vendor-released patch has been identified at time of analysis. As a workaround, restrict access to /admin/deletemanagerclinic.php to trusted administrators via IP whitelisting or web server access controls, or disable the endpoint entirely. Apply parameterized queries or strict input validation to the 'clinic' parameter. Monitor the VulDB entry (https://vuldb.com/?id.336982) and GitHub issue for updates.

Technical ContextAI · show details

The vulnerability exists in a PHP web application (anisha:online_appointment_booking_system version 1.0) that uses SQL databases. The /admin/deletemanagerclinic.php script fails to properly neutralize special elements in the 'clinic' parameter before using it in an SQL query, resulting in an injection flaw classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component). This allows attackers to embed arbitrary SQL code.
