OS Command Injection in Realtek rtl819x Jungle SDK boa formWsc targetAPSsid

IdentifiersCVE-2023-50381CWE-78· Improper Neutralization of Special…

CVE-2023-50381 is an OS command injection vulnerability in the boa web server's formWsc functionality in Realtek rtl819x Jungle SDK v3.4.11. The issue is associated with the targetAPSsid request parameter. A specially crafted series of HTTP requests can cause attacker-controlled input from targetAPSsid to be incorporated into an OS command without proper neutralization, resulting in arbitrary command execution on the affected device.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows arbitrary OS command execution on the vulnerable device. On affected embedded Realtek-based routers or IoT devices, this can enable full device compromise, including malware deployment, botnet enrollment, configuration tampering, persistence establishment, and use of the device for follow-on activity such as DDoS operations or proxying.

Mitigation

If you can’t patch tonight, do this now.

Restrict or eliminate exposure of the boa management interface from untrusted networks, especially the public Internet. Disable remote administration and WSC-related functionality if not required. Place management interfaces behind VPNs or trusted network boundaries, enforce network ACLs, and monitor HTTP requests targeting formWsc and anomalous command execution on embedded devices. Where possible, segment vulnerable devices and apply compensating controls until patched firmware is available.

Remediation

Patch, then assume compromise.

Upgrade to a vendor-provided fixed firmware or SDK build that addresses CVE-2023-50381. Because rtl819x Jungle SDK is incorporated into downstream OEM firmware, remediation may require obtaining updated firmware from the device manufacturer rather than Realtek directly. If no patch is available, replace affected devices or firmware with supported versions that do not include the vulnerable formWsc implementation.
