Ocuco Innovation Privilege Escalation Vulnerability in INNOVASERVICEINTF.EXE

A vulnerability in Ocuco Innovation's INNOVASERVICEINTF.EXE version 2.10.24.17 allows attackers to bypass authentication and escalate privileges to Administrator. This is achieved by intercepting and modifying TCP packets, manipulating the login process to gain unauthorized administrative access.

Impact

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

Reproduction

To reproduce this vulnerability, log into the Ocuco Innovation software 'Innovations Service Interface' with a privileged account. Intercept the TCP packets and modify them by changing certain bytes to whitespace in hexadecimal. This manipulation causes an access violation error, indicating that the program attempted to read a memory address it was not authorized to access. After this modification, the software no longer requires privileged login, effectively granting administrative rights. With these rights, access can be gained to all functions of the software, including user management features.

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.
