CVE-2026-58146: CWE-78 Improper neutralization of special elements used in an OS command ('OS command injection') in WNC T-Mobile 5G Box IDU
WNC T-Mobile 5G Box IDU router is vulnerable to OS command injection vulnerability. The vulnerability exists within the /cgi-bin/portal.cgi endpoint, specifically through the cli_cookie POST parameter. The cli_cookie parameter value is directly concatenated into a find command string without proper sanitization. This allows a remote, unauthenticated attacker to inject and execute arbitrary shell commands as root on the underlying operating system. This issue has been fixed in firmware version 1.1.0.651412
AI Analysis
Technical Summary
CVE-2026-58146 is an OS command injection vulnerability in the WNC T-Mobile 5G Box IDU router. The flaw exists because the cli_cookie POST parameter is concatenated unsafely into a find command string in the /cgi-bin/portal.cgi endpoint, enabling remote unauthenticated attackers to execute arbitrary shell commands with root privileges. This vulnerability is addressed by updating to firmware version 1.1.0.651412.
Potential Impact
Successful exploitation allows remote unauthenticated attackers to execute arbitrary commands as root on the underlying operating system, potentially leading to full system compromise. The vulnerability is critical due to the high privileges obtained and the lack of authentication required for exploitation.
Mitigation Recommendations
Apply the official firmware update to version 1.1.0.651412 or later, which fixes this vulnerability. No other mitigations are specified. Ensure devices are updated promptly to prevent exploitation.
