Operationally, exploitation aligns with the MITRE ATT&CK technique Data Obfuscation (T1001); ranked in the top 2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

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.

Patching/maintenance can remediate known path-traversal flaws in deployed software (partial prevention of exploitability) but does nothing to stop the coding defect from being introduced in the first place.

PR.AA-05 none match

PR.AA-05 defines and reviews access policies but does not address code-level pathname neutralization, so neither direction prevents CWE-22.
