DescriptionCVE.org

A weakness has been identified in SourceCodester Onlne Examination & Learning Management System 1.0. Affected by this issue is some unknown functionality of the file /announcements.php. Executing a manipulation can lead to unrestricted upload. The attack can be executed remotely. The exploit has been made available to the public and could be used for attacks. The name of the affected product appears to have a typo in it.

AnalysisAI

Unrestricted file upload in SourceCodester's "Onlne Examination & Learning Management System" 1.0 (note: product name contains a known typo per CVE data) exposes the /announcements.php endpoint to arbitrary file upload by low-privileged authenticated users. A publicly available proof-of-concept, referenced under the title 'OE-LMS-RCE-3-announcements.md', demonstrates that the flaw can be leveraged for remote code execution - a significantly more severe real-world impact than the low CIA metrics in the provided CVSS 4.0 score suggest. …

Vulnerability AssessmentAI

Exploitation Exploitation requires a valid low-privileged account on the SourceCodester LMS installation - the CVSS 4.0 vector specifies PR:L, meaning unauthenticated exploitation is not possible. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The provided CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N) confirms low-complexity, network-accessible, low-privilege exploitation with no user interaction - strong exploitability signals. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An authenticated user with low-privileged access (e.g., a student or staff account) navigates to /announcements.php and uploads a PHP webshell file disguised with a crafted filename. Because the server performs no meaningful file type validation, the malicious .php file is stored in a web-accessible directory. …
Remediation No vendor-released patch has been identified at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report.
