Ocuco Innovation Privilege Escalation Vulnerability via TCP Packet Modification

A privilege escalation vulnerability has been identified in Ocuco Innovation Tracking.exe version 2.10.24.51. This vulnerability allows local attackers to gain unauthorized administrative access by intercepting and modifying TCP packets. The manipulation of packet data can bypass authentication checks, enabling attackers to access sensitive functions within the software as an administrator.

Impact

Exploitation of this vulnerability could lead to unauthorized administrative access, allowing attackers to manipulate critical data, disrupt normal operations, and potentially cause legal and reputational damage.

Reproduction

To reproduce this vulnerability, log into the Ocuco Innovation software with a privileged account. Then, intercept the TCP packets being sent during the login process. Modify the intercepted packets by replacing certain bytes with whitespace, effectively erasing the original data. This alteration can create an access violation error, indicating that the software has attempted to read a memory address it is not permitted to access. However, this modification also bypasses the authentication requirement, granting access to the application as an administrator. Once logged in, navigate to the user management section to create a new administrative user, successfully exploiting the vulnerability.

Remediation

It is recommended to restrict network access to this software to authorized users only, until a patched version is available. Additionally, implementing stronger authentication mechanisms, using encrypted communication channels, and conducting regular security audits can help mitigate this vulnerability.
