CVE-2024-41197: Critical Authentication Bypass in Ocuco Innovation Software

Overview

The vulnerability in question, designated as CVE-2024-41197, poses a significant threat to organizations utilizing Ocuco Innovation – INVCLIENT.EXE v2.10.24.5. This vulnerability allows attackers to bypass authentication and escalate privileges to an Administrator level through the use of a crafted TCP packet. The implications of this vulnerability are serious, as it could potentially lead to system compromise and data leakage. It is therefore critical for entities using this software to understand the vulnerability and take immediate steps to mitigate its effects.

Ocuco Innovation – INVCLIENT.EXE | v2.10.24.5

How the Exploit Works

The exploit takes advantage of a flaw in the authentication process of the INVCLIENT.EXE software. By sending a specially crafted TCP packet to a vulnerable system, an attacker can bypass the standard authentication processes. This gives the attacker the ability to escalate their privileges to that of an Administrator, granting them virtually unrestricted access to the system.

Conceptual Example Code

The following pseudocode illustrates a potential way this vulnerability may be exploited:

import socket
target_ip = "target.example.com"
target_port = 1234  # the port where INVCLIENT.EXE is listening
# craft a malicious TCP packet
packet = "crafted_packet_to_bypass_authentication"
# create a socket object
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
# connect to the target
s.connect((target_ip, target_port))
# send the malicious TCP packet
s.send(packet)
# close the connection
s.close()

In this hypothetical example, an attacker creates a malicious TCP packet designed to bypass the authentication process of the INVCLIENT.EXE software. The attacker then sends this packet to the target system, resulting in an authentication bypass and the escalation of their privileges to Administrator level.

Recommendation for Mitigation

Users of Ocuco Innovation’s INVCLIENT.EXE v2.10.24.5 are advised to apply the vendor patch as soon as it becomes available. Until then, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary mitigation measures. Regular monitoring and updating of systems can also help to prevent future vulnerabilities.
