CVE-2023-22335 in SS1
Summary
by MITRE • 03/06/2023
Improper access control vulnerability in SS1 Ver.13.0.0.40 and earlier and Rakuraku PC Cloud Agent Ver.2.1.8 and earlier allows a remote attacker to bypass access restriction and download an arbitrary file of the directory where the product runs. As a result of exploiting this vulnerability with CVE-2023-22336 and CVE-2023-22344 vulnerabilities together, it may allow a remote attacker to execute an arbitrary code with SYSTEM privileges by sending a specially crafted script to the affected device.

This vulnerability represents a critical improper access control flaw affecting SS1 version 13.0.0.40 and earlier, as well as Rakuraku PC Cloud Agent version 2.1.8 and earlier. The weakness stems from inadequate input validation and authentication mechanisms that fail to properly restrict file access within the application's directory structure. Attackers can exploit this vulnerability to bypass normal access controls and download arbitrary files from the system where the vulnerable software operates, effectively compromising the confidentiality and integrity of sensitive data. The vulnerability aligns with CWE-285, which specifically addresses improper authorization issues in software systems.
The technical exploitation of this vulnerability creates a dangerous chain of compromise when combined with CVE-2023-22336 and CVE-2023-22344. These interconnected flaws form a sophisticated attack vector that enables remote code execution with SYSTEM privileges. The attacker can craft malicious scripts and transmit them to the vulnerable device, leveraging the initial access control bypass to establish persistent access to the target system. This multi-stage exploitation approach demonstrates the severity of the vulnerability chain, as it transitions from simple file access to full system compromise. The attack pattern follows typical ATT&CK techniques for privilege escalation and command execution within compromised environments.
The operational impact of this vulnerability extends beyond immediate data theft to encompass complete system takeover capabilities. Organizations running affected versions face potential unauthorized access to sensitive corporate data, system files, and configuration information. The ability to execute code with SYSTEM privileges means attackers can install backdoors, modify system configurations, or establish persistent access points within the network. This vulnerability particularly affects environments where these specific software products are deployed for remote management or cloud services, creating potential entry points for broader network infiltration. The risk is compounded by the remote nature of the attack, which eliminates the need for physical access or local network presence.
Mitigation strategies should prioritize immediate patching of affected software versions to address the core access control flaws. Organizations must implement network segmentation to limit exposure of vulnerable systems and deploy intrusion detection systems to monitor for suspicious file access patterns. Additional protective measures include restricting network access to affected services, implementing strict firewall rules, and conducting comprehensive vulnerability assessments to identify other potential entry points. Security teams should also establish monitoring protocols for unusual file download activities and ensure proper access controls are enforced through regular security audits. The remediation process must include verification that all affected systems have been properly updated and that no residual vulnerabilities remain in the network infrastructure.
