CVE-2022-3365 in Remote Mouse Server
Summary
by MITRE • 01/28/2025
Due to reliance on a trivial substitution cipher, sent in cleartext, and the reliance on a default password when the user does not set a password, the Remote Mouse Server by Emote Interactive can be abused by attackers to inject OS commands over theproduct's custom control protocol. A Metasploit module was written and tested against version 4.110, the current version when this CVE was reserved.

The vulnerability in Remote Mouse Server by Emote Interactive represents a critical security flaw that stems from poor cryptographic implementation and weak authentication mechanisms. This issue manifests through the use of a trivial substitution cipher for communication encryption, which operates in cleartext format, making it susceptible to interception and manipulation by malicious actors. The system's reliance on default passwords when users fail to set custom authentication credentials creates an additional attack vector that significantly weakens the overall security posture of the application.
The technical exploitation of this vulnerability occurs through the product's custom control protocol, which allows attackers to inject operating system commands directly into the system. This command injection capability arises from the combination of weak encryption and default credential usage, creating a pathway for remote code execution. The trivial substitution cipher implementation provides minimal security protection, as it can be easily reverse-engineered or brute-forced by attackers who intercept network traffic. This weakness directly aligns with CWE-310, which addresses cryptographic issues and improper implementation of cryptographic functions.
The operational impact of this vulnerability extends beyond simple unauthorized access, as it enables complete system compromise through remote command execution. Attackers can leverage this vulnerability to gain full control over affected systems, potentially leading to data theft, system corruption, or further network infiltration. The Metasploit module developed for this exploit demonstrates the practical nature of the threat, as it was specifically tested against version 4.110, indicating that the vulnerability remains active in the current release when this CVE was reserved. This represents a significant risk to organizations that deploy this software without proper security hardening measures.
Security mitigation strategies should focus on immediate credential management and cryptographic strengthening. Organizations must enforce mandatory password policies and disable default accounts immediately upon installation. Network segmentation and firewall rules should restrict access to the Remote Mouse Server ports to minimize attack surface. The implementation of stronger encryption protocols and authentication mechanisms would address the core issues identified in this vulnerability. Additionally, regular security assessments and vulnerability scanning should be conducted to identify similar cryptographic weaknesses in other network services. This vulnerability exemplifies the importance of following security best practices as outlined in the ATT&CK framework, particularly in the credential access and execution domains where weak authentication and command injection vulnerabilities can lead to complete system compromise.
