DescriptionCVE.org

A security vulnerability has been detected in SourceCodester Class and Exam Timetabling System 1.0. This issue affects some unknown processing of the file /edit_subject1.php. The manipulation of the argument ID leads to sql injection. The attack is possible to be carried out remotely. The exploit has been disclosed publicly and may be used.

AnalysisAI

SQL injection in SourceCodester Class and Exam Timetabling System 1.0 exposes the /edit_subject1.php endpoint to unauthenticated remote attackers who can manipulate the ID parameter to execute arbitrary SQL against the underlying database. The vulnerability carries a CVSS 4.0 score of 6.9 with no authentication or user interaction required, and a proof-of-concept exploit has been publicly disclosed via GitHub. …

Vulnerability AssessmentAI

Exploitation No special conditions are required for exploitation beyond network reachability of the `/edit_subject1.php` endpoint. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 score of 6.9 (Medium) reflects limited but real impact across confidentiality, integrity, and availability - all rated Low - consistent with a SQL injection that allows partial data read/write rather than full database compromise or OS-level access. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker identifies an internet-exposed instance of the Class and Exam Timetabling System and sends a crafted HTTP GET or POST request to `/edit_subject1.php` with a malicious SQL payload in the `ID` parameter - for example, appending `' UNION SELECT username,password,3 FROM users-- -`. Because a public proof-of-concept exists on GitHub (https://github.com/i-QvQ-i/first-OvO/issues/7), the attacker can adapt existing exploit code with minimal effort to enumerate database tables, extract credentials, or modify timetable records.
Remediation No vendor-released patch has been identified at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report.
