Vulnerability AssessmentAI

Exploitation No special conditions - remote unauthenticated exploitation against default configurations of the imvks786 Student Management System admin login page. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 base score of 5.5 (Medium) reflects low individual impact ratings (VC:L/VI:L/VA:L) on paper, but the attack conditions are maximally permissive: network-reachable, no authentication, no complexity, no user interaction (AV:N/AC:L/AT:N/PR:N/UI:N). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An unauthenticated remote attacker sends a crafted HTTP POST request to admin/admin_login.php with a SQL injection payload in the a_usr or a_pwd parameter - for example, setting a_usr to a value such as ' OR '1'='1'-- to manipulate the authentication query logic. Because a public proof-of-concept has been released via the project's GitHub issue tracker, the specific payload and technique are already disclosed and readily usable with no special tooling. …
Remediation No vendor-released patch has been identified at time of analysis - the project maintainer was notified via a GitHub issue report but has not responded. … Detailed patch versions, workarounds, and compensating controls in full report.

Threat intelligence, references, and detailed analysis are available after sign-in.
