The vulnerability stems from CWE-434 (Unrestricted Upload of File with Dangerous Type), a class of flaw that on PHP-backed NAS web interfaces frequently enables follow-on code execution by uploading a web shell. A public proof-of-concept exploit is available, elevating the realistic risk beyond what the moderate CVSS 4.0 base score of 6.9 alone would suggest, though no CISA KEV listing confirms active in-the-wild campaigns at time of analysis.
Unrestricted file upload in D-Link DNS-320 NAS firmware 1.0.2 exposes the `/web/web_file/upload.php` endpoint to unauthenticated remote attackers who can upload arbitrary file types - including PHP webshells - enabling effective remote code execution on the device. The CVSS 4.0 base vector confirms no authentication, user interaction, or special attack conditions are required (PR:N/UI:N/AC:L). A public exploit has been disclosed (CVSS 4.0 E:P modifier, corroborated by a referenced Feishu exploit document), and the DNS-320 is an end-of-life device for which no vendor patch has been identified, leaving exposed deployments persistently vulnerable.
Least-privilege violation in the D-Link DIR-823G router (firmware 1.0.2B05_20181207) stems from insecure configuration of the Boa web server via /etc/boa/boa.conf, allowing an authenticated remote attacker to abuse over-broad privileges to compromise confidentiality, integrity, and availability. Publicly available exploit code exists, but the CVSS 4.0 vector rates attack complexity high (AC:H) and vendor guidance notes exploitation is difficult; there is no public exploit identified as actively exploited (not in CISA KEV). EPSS data was not supplied, but the low-privilege network vector combined with full CIA impact makes this a meaningful risk on exposed devices.
