What is CVE-2026-35869?

A Command Injection vulnerability has been identified in the bs_SetLimitCli_info function of the libshare.so library used in LB-link Router AC450M. This issue arises from inadequate validation and sanitization processes of user inputs before these are utilized in executing system-level commands. By taking advantage of this vulnerability, an attacker can inject specially crafted shell metacharacters or malicious payloads into the affected parameter, leading to the execution of arbitrary operating system commands. Such exploitation can significantly jeopardize the security posture of the affected system, allowing unauthorized access and control.
