Description
The SMS control function of IE-SR-2TX-WL-4G devices can require a password for SMS commands via the 'Enable Password Authorization' setting. The device increments a retry counter on each failed SMS password attempt; after 5 consecutive failed attempts, SMS password authorization is automatically disabled. An unauthenticated remote attacker who is able to send SMS messages to the device can deliberately trigger this by submitting 5 or more invalid passwords, after which subsequent SMS commands are executed without requiring a password, resulting in potential limited configuration tampering, limited information leakage and potentially full loss of availability.
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-2026-63587 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-2026-63587 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-2026-63587. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
