AnalysisAI

Session fixation (CWE-384) in ningzichun Student Management System allows a remote attacker to pre-set a victim's session identifier via login.php, then hijack the authenticated session after the victim logs in. The login.php file's use of session_start fails to regenerate the session ID upon successful authentication, making any pre-supplied session ID persist into the authenticated state. …

Vulnerability AssessmentAI

Exploitation The attacker must be able to deliver a crafted link or set a session cookie on the victim's browser before the victim logs in - typically via phishing, a shared network, or a co-located web page. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 score of 2.1 reflects the realistic impact accurately: attack vector is network, complexity is low, and no privileges are required from the attacker, but user interaction (UI:P) is mandatory - the victim must both receive a crafted link and complete a login workflow with the fixed session. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation No vendor-released patch has been identified at time of analysis - the project maintainer has not responded to the GitHub issue disclosure. … Detailed patch versions, workarounds, and compensating controls in full report.
