High impact if exploited, but EPSS currently rates exploitation as unlikely (1.36%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

A Command Injection vulnerability exists in the bs_SetLimitCli_info function within the libshare.so library of LB-link Router AC2100_AZ3 V1.0.4. This flaw occurs due to insufficient validation and sanitization of user-supplied input before it is passed to a system-level command execution context. An attacker can exploit this vulnerability by injecting specially crafted shell metacharacters or payloads into the vulnerable parameter, resulting in the execution of arbitrary operating system commands.
