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.
Detection & mitigation playbook
VulnerabilityDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for the affected component. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of the affected component has shipped for CVE-2026-35868 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2026-35868 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2026-35868. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
