2DescriptionCVE.org
A vulnerability was identified in SourceCodester Student Grades Management System 1.0. Affected by this issue is some unknown functionality of the file students.php. The manipulation of the argument Remarks leads to cross site scripting. Remote exploitation of the attack is possible. The exploit is publicly available and might be used.
AnalysisAI
Cross-site scripting in SourceCodester Student Grades Management System 1.0 allows a low-privileged authenticated attacker to inject malicious JavaScript via the unvalidated 'Remarks' parameter in students.php, executing arbitrary scripts in the context of a victim's browser session upon passive viewing. A public proof-of-concept exists on GitHub; however, this CVE is not listed in the CISA KEV catalog and the EPSS score of 0.03% (9th percentile) reflects very low real-world exploitation probability. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to hold a valid, low-privilege authenticated account within the Student Grades Management System (PR:L per CVSS 4.0 vector) with write access to the Remarks field in students.php. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Multiple signals converge on low real-world risk despite the existence of a public proof-of-concept. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An authenticated low-privilege user - such as a student or data-entry clerk with write access to the Remarks field - injects a JavaScript payload (e.g., a cookie-stealing script) into the Remarks parameter via students.php. When a higher-privileged user such as a teacher or administrator subsequently views the student record containing the injected content, the script executes in their browser session, potentially enabling session token theft or unauthorized UI manipulation. … |
| Remediation | No vendor-released patch has been identified at the time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report. |
