CVE-2023-50612 is a high-severity vulnerability identified in fit2cloud Cloud Explorer Lite version 1.4.1. The vulnerability stems from insecure permissions related to the 'cloud accounts' parameter, which allows local attackers to escalate their privileges and access sensitive information. Specifically, the flaw is categorized under CWE-276, which involves improper permissions or access control settings. An attacker with local access to the affected system can exploit this vulnerability to gain higher privileges than intended, potentially leading to unauthorized disclosure of sensitive cloud account credentials or configuration data. The CVSS 3.1 base score of 7.8 reflects a high impact on confidentiality, integrity, and availability, with low attack complexity and requiring only low privileges but no user interaction. Although no public exploits are currently known, the vulnerability poses a significant risk due to the sensitive nature of cloud account information and the potential for privilege escalation within the environment. The lack of vendor or product details beyond the version and product name limits the scope of technical specifics, but the core issue revolves around improper permission settings that can be leveraged locally to compromise system security.

For European organizations, this vulnerability could have serious implications, especially for those relying on fit2cloud Cloud Explorer Lite for managing cloud resources. Unauthorized privilege escalation could lead to exposure of cloud account credentials, enabling attackers to manipulate cloud environments, exfiltrate data, or disrupt services. This risk is heightened in sectors with stringent data protection requirements such as finance, healthcare, and critical infrastructure, where cloud environments often hold sensitive or regulated data. The compromise of cloud accounts could also lead to lateral movement within corporate networks, further amplifying the impact. Given the local attack vector, insider threats or attackers who have gained initial footholds could exploit this vulnerability to deepen their access. The absence of known exploits in the wild currently reduces immediate risk but does not diminish the urgency for remediation, as attackers may develop exploits once the vulnerability details become widely known.

Organizations should immediately review and harden permission settings related to the cloud accounts parameter in fit2cloud Cloud Explorer Lite. Specific steps include: (1) Restricting local user permissions to the minimum necessary, ensuring that only authorized administrators have access to sensitive configuration files or parameters. (2) Implementing strict access control policies and auditing permission changes regularly to detect misconfigurations. (3) Monitoring local user activities for unusual privilege escalation attempts. (4) Applying any available patches or updates from the vendor as soon as they are released. (5) If patches are not yet available, consider isolating or limiting the use of the affected software, especially on systems with multiple users or where local access cannot be tightly controlled. (6) Employing endpoint detection and response (EDR) tools to identify suspicious local privilege escalation behaviors. (7) Educating system administrators and users about the risks of local privilege escalation and enforcing strong local account management practices.
