Deeper analysis

CVE-2023-47464 is an insecure permissions vulnerability, tracked under CWE-22, that affects the upload API function in GL.iNet AX1800 firmware versions 4.0.0 through 4.4.x. The flaw permits path traversal or unauthorized file placement during upload operations, enabling remote code execution on the device.

An attacker with valid low-privileged credentials can reach the affected API over the network and supply crafted upload requests. Successful exploitation grants the ability to write arbitrary files, resulting in full compromise of confidentiality, integrity, and availability on the router.

Public disclosure is documented in the GL.iNet CVE repository, which details the arbitrary file creation vector through the upload endpoint and identifies the fixed release as version 4.5.0. The associated EPSS score has remained at 0.7010 with no indicated upward trajectory after publication.
