SourceCodester Patient Appointment Scheduler System v1.0 is vulnerable to arbitrary code execution (RCE) via /scheduler/classes/SystemSettings.php?f=update_settings.
AnalysisAI
SourceCodester Patient Appointment Scheduler System v1.0 suffers from SQL injection in the SystemSettings.php update_settings function, allowing authenticated high-privilege administrators to execute arbitrary SQL queries. While tagged as RCE, the CVSS vector (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:N/A:N) and SSVC framework indicate limited confidentiality impact with no confirmed integrity or availability consequences; this is primarily a SQL injection vulnerability requiring administrative credentials with no public exploit code identified at time of analysis.
Technical ContextAI
The vulnerability resides in CWE-89 (SQL Injection) within SourceCodester's Patient Appointment Scheduler System, specifically in the /scheduler/classes/SystemSettings.php file's update_settings parameter handler. The application fails to properly sanitize or parameterize SQL queries constructed from the 'f' parameter input, enabling authenticated attackers with high-privilege (PR:H per CVSS) administrative roles to inject malicious SQL. While the CVE is tagged as RCE, the actual attack vector is SQL injection; RCE claims may be derivative assumptions about potential secondary impact rather than direct code execution.
RemediationAI
No vendor-released patch identified at time of analysis. Immediate mitigation requires updating to a patched version if SourceCodester releases a security update; however, given the placeholder CPE and missing vendor contact data, organizations should contact SourceCodester directly or monitor their GitHub repository (referenced in cveorg link) for patches. In the interim, restrict administrative access to the /scheduler/classes/SystemSettings.php endpoint via web application firewall rules, implement input validation on the 'f' parameter using prepared statements or parameterized queries, enforce strong administrative password policies, and audit all administrator accounts for unauthorized access.
