CVE-2023-48849

CVSS 9.8v3.1pub. 2023-12-06upd. 2024-11-21

Ruijie EG Series Routers version EG_3.0(1)B11P216 and before allows unauthenticated attackers to remotely execute arbitrary code due to incorrect filtering.

🤖 AI Analysis
How it works

The vulnerability results from improper filtering of data transmitted to the device, which allows an attacker to craft a malicious network request without requiring authentication. The lack of proper input validation enables the submission and execution of arbitrary code directly on the vulnerable device. The attack is possible remotely over the network without any prerequisites on the attacker's side.

Impact

An attacker can gain full control of the device by executing arbitrary code with its privileges, which may lead to compromises of confidentiality, integrity, and availability of the entire network infrastructure served by the router.

Mitigation & patch

Update firmware to a version newer than EG_3.0(1)B11P216. Apply patches available from the manufacturer according to the references. Until updates are implemented, it is recommended to restrict access to the device management interface only to trusted IP addresses and isolate routers from the public Internet using a firewall.

Who is affected

Ruijie EG Series Routers (RG-EG1000C, RG-EG1000E, RG-EG105G) with firmware version EG_3.0(1)B11P216 and earlier
