Technical Analysis
This vulnerability exists due to inadequate sanitization of user-supplied input passed to system-level command execution within the bs_SetLimitCli_info function of the libshare.so library on LB-link Router AC2100_AZ3 V1.0.4. An attacker can inject shell metacharacters or crafted payloads to execute arbitrary operating system commands, potentially leading to full system compromise. The CVSS v3.1 score is 9.8 (critical), reflecting network attack vector, no privileges required, no user interaction, and high impact on confidentiality, integrity, and availability. No patch or official remediation information is currently available, and no known exploits in the wild have been reported.
Potential Impact
Successful exploitation allows remote attackers to execute arbitrary OS commands on the affected router without authentication, leading to complete compromise of the device's confidentiality, integrity, and availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict network access to the affected device and monitor for suspicious activity related to command injection attempts.
