DescriptionCVE.org

A vulnerability was determined in SourceCodester Syllabus-Aligned Learning Management & Examination System 1.0. The impacted element is an unknown function of the file auth_process.php of the component Login. This manipulation causes session fixiation. It is possible to initiate the attack remotely. The exploit has been publicly disclosed and may be utilized.

AnalysisAI

Session fixation in SourceCodester Syllabus-Aligned Learning Management & Examination System 1.0 allows unauthenticated remote attackers to pre-plant a session identifier via the auth_process.php login endpoint, then hijack the authenticated session after a victim logs in. The auth_process.php component fails to regenerate the session ID upon successful authentication, enabling full account takeover of any user who can be socially engineered into authenticating through a crafted link. …

Vulnerability AssessmentAI

Exploitation The attack requires the victim to authenticate to the LMS using an attacker-controlled session identifier, which means the attacker must first deliver a crafted login URL to the victim and persuade them to use it to log in (UI:P/UI:A - active user interaction is mandatory). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The provided CVSS 4.0 score of 2.1 with VC:L/VI:L/VA:L materially understates real-world impact: successful session fixation yields a fully authenticated session, which in practice means C:H/I:H against the victim's account data and capabilities. … 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. … Detailed patch versions, workarounds, and compensating controls in full report.
