Description
PLANET IGS-5225-8P2T4S industrial managed switch V1 and V2 firmware versions bfore 1.2412b260707 and 2.2412b260519 contain a stack-based buffer overflow in the web server. Insufficient bounds checking on data copied into a stack buffer allows a remote administrator to cause a denial of service or potentially execute arbitrary code on the underlying operating system.
Detection & mitigation playbook
VulnerabilityDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for the affected component, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
No patched version of the affected component has shipped for CVE-2026-81945 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2026-81945 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2026-81945. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2026-81945 in your dependencies?
O3 Security finds CVE-2026-81945 across dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
