CVE-2023-1854Public exploitNetwork attack vector

Persistent admin access after session removal

Published Apr 5, 2023 · Updated Aug 2, 2024

Insufficient session expiration in SourceCodester Online Graduate Tracer System 1.0 allows remote authenticated users to retain admin access. Administrative pages continue serving privileged functions after the browser cookies carrying the authenticated session are deleted, rather than requiring a valid session on each request. Exploitation requires an established administrator login and preserves access to administrative functions after the session material is removed.
