CVE-2024-58275 is a command injection vulnerability classified under CWE-88, affecting Easywall version 0.3.1, a network management or firewall-related software developed by jpylypiw. The vulnerability resides in the /ports-save endpoint, which processes input parameters without properly neutralizing argument delimiters such as shell metacharacters. This improper sanitization allows an authenticated attacker to inject arbitrary shell commands, leading to remote code execution on the server hosting Easywall. The vulnerability requires the attacker to have valid credentials (privileged or otherwise) to access the endpoint, but does not require further user interaction. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no user interaction (UI:N), and privileges required (PR:L), with high impact on confidentiality, integrity, and availability (all rated high). This means an attacker with limited privileges can escalate control by executing arbitrary commands, potentially compromising the entire system. No patches or fixes are currently linked, and no known exploits have been reported in the wild, but the vulnerability is publicly disclosed and should be considered critical for affected users. The flaw can be exploited to manipulate firewall rules, exfiltrate data, or pivot within the network, posing significant risks to organizational security.

For European organizations, this vulnerability poses a significant risk to network security and operational continuity. Easywall is likely used in network perimeter defense or internal segmentation, so exploitation could lead to unauthorized access, data breaches, or disruption of network services. The ability to execute arbitrary commands can allow attackers to disable security controls, install malware, or move laterally within the network. Confidentiality is at risk due to potential data exfiltration, integrity is compromised by unauthorized changes to firewall or network configurations, and availability may be impacted by service disruption or denial-of-service conditions. Organizations in critical infrastructure sectors, government, finance, and telecommunications are particularly vulnerable due to the strategic importance of their network defenses. The requirement for authentication limits exposure but does not eliminate risk, especially if credential theft or weak authentication mechanisms exist. The lack of known exploits currently provides a window for proactive mitigation before active exploitation occurs.

Immediate mitigation should focus on restricting access to the /ports-save endpoint to only highly trusted administrators and implementing multi-factor authentication to reduce the risk of credential compromise. Network segmentation and firewall rules should limit exposure of Easywall management interfaces to internal networks or VPNs. Input validation and sanitization must be applied to all parameters accepted by the /ports-save endpoint to neutralize shell metacharacters and prevent injection. If possible, upgrade to a patched version once available or apply vendor-provided workarounds. Monitoring and logging of access to the vulnerable endpoint should be enhanced to detect suspicious activities indicative of exploitation attempts. Conduct regular credential audits and enforce strong password policies to minimize the risk of unauthorized authentication. Consider deploying application-layer firewalls or intrusion detection systems capable of detecting command injection patterns targeting Easywall. Finally, prepare incident response plans specific to potential compromise scenarios involving Easywall.
