Ocuco Innovation Report Server Authentication Bypass and Privilege Escalation Vulnerability

An authentication bypass vulnerability allowing unauthorized privilege escalation to Administrator has been identified in Ocuco Innovation's Report Server component, specifically in version 2.10.24.13. This vulnerability arises from improper authorization checks, enabling attackers to manipulate the login process via crafted TCP packets, thereby gaining administrative access without authentication.

Impact

Exploitation of this vulnerability allows unauthorized users to gain administrative access to the Ocuco Innovation software, bypassing authentication requirements. This access can be used to manipulate sensitive data, disrupt normal operations, and create new administrative users, all of which could lead to significant security risks and potential legal consequences.

Reproduction

To reproduce this vulnerability, intercept TCP packets sent during the login process of the Report Server application. Modify the intercepted packets by replacing certain bytes with whitespace, then send the modified packet. This manipulation causes the application to crash, indicating a successful bypass of authentication. After the crash, the application no longer requires a privileged login, allowing access as an Administrator. Once logged in, the vulnerability can be demonstrated by creating a new user account with administrative privileges through the application's user management interface.

Remediation

Users are advised to restrict network access to the affected software to authorized personnel only, until a patched version is available. Regular security audits and monitoring of network traffic for suspicious activities can also help mitigate potential exploitation of this vulnerability.
