CVE-2024-41197 is a critical security vulnerability identified in the Ocuco Innovation software component INVCLIENT.EXE version 2.10.24.5. This vulnerability allows an unauthenticated attacker to bypass authentication mechanisms and escalate privileges to Administrator level by sending a specially crafted TCP packet. The vulnerability is classified under CWE-287, which relates to improper authentication. The CVSS v3.1 base score of 9.8 indicates a critical severity, reflecting the high impact on confidentiality, integrity, and availability. The attack vector is network-based (AV:N), requiring no privileges (PR:N) and no user interaction (UI:N), making exploitation relatively straightforward remotely. The scope is unchanged (S:U), meaning the vulnerability affects the same security scope. Successful exploitation grants full administrative control, potentially allowing attackers to manipulate system configurations, access sensitive data, deploy malware, or disrupt services. Although no public exploits are currently known in the wild, the critical nature and ease of exploitation make this a significant threat. The lack of vendor or product details beyond the executable name limits precise identification of affected environments, but the presence of INVCLIENT.EXE suggests usage in specific Ocuco Innovation software deployments, possibly in sectors relying on this software for operational purposes.

For European organizations, this vulnerability poses a severe risk, especially those using Ocuco Innovation software or related products incorporating INVCLIENT.EXE. The ability to bypass authentication and gain administrator privileges remotely can lead to full system compromise, data breaches, operational disruptions, and potential lateral movement within networks. Critical infrastructure, healthcare, financial institutions, and enterprises with sensitive data are particularly vulnerable to exploitation consequences. The attack requires no user interaction and can be executed remotely, increasing the risk of widespread exploitation if the software is exposed to untrusted networks. The absence of a patch or mitigation guidance at this time exacerbates the threat, potentially allowing threat actors to develop exploits rapidly. European organizations must consider the regulatory implications of breaches, including GDPR compliance and potential fines for data loss or unauthorized access.

Given the absence of an official patch, European organizations should immediately undertake the following specific actions: 1) Conduct a thorough inventory to identify all instances of INVCLIENT.EXE version 2.10.24.5 or related Ocuco Innovation software components in their environment. 2) Restrict network exposure of affected systems by implementing strict firewall rules to block inbound TCP traffic to ports used by INVCLIENT.EXE, limiting access to trusted internal networks only. 3) Employ network intrusion detection/prevention systems (IDS/IPS) with custom signatures to detect and block suspicious TCP packets that could exploit this vulnerability. 4) Monitor logs and network traffic for anomalous connection attempts or privilege escalation indicators related to INVCLIENT.EXE. 5) Engage with Ocuco Innovation or software vendors for updates or patches and apply them promptly once available. 6) Implement robust network segmentation to isolate critical systems running the vulnerable software, minimizing lateral movement potential. 7) Enhance endpoint protection with behavioral analytics to detect unauthorized privilege escalations. 8) Prepare incident response plans specific to this vulnerability to enable rapid containment and remediation if exploitation is detected.
