CVE-2023-7055Public exploitNetwork attack vector

Authenticated contact-number tampering

Published Dec 22, 2023 · Updated Aug 2, 2024

Improper access control in PHPGurukul Online Notes Sharing System 1.0 allows remote authenticated users to change contact numbers via crafted requests. The /user/profile.php Contact Information Handler accepts a modified mobilenumber parameter even though the browser form prevents direct editing, allowing unauthorized profile data writes. Login is required and the demonstrated consequence is alteration of the victim user's contact information, which can support impersonation or social engineering.
