Summary

A command injection vulnerability exists in the bs_SetLimitCli_info function within the libshare.so library of the LB-LINK router AC1900_AZ2 V1.0.2 via shell metacharacters. It is reachable when an actor can make a POST /goform/set_LimitClient_cfg call but does not already have administrative access to the device.

Risk Assessment

An attacker with network access to the router interface can execute arbitrary system commands, leading to full device compromise and traffic manipulation. This may result in data interception, DNS configuration changes, or use of the router as a foothold for further attacks.

Recommendation

Update the LB-LINK AC1900_AZ2 router firmware to a version containing the fix and restrict administrative interface access to trusted networks only. Until patched, disable WAN access to the management panel.
