Summary

CVE-2022-37055 is a critical-severity Classic Buffer Overflow (CWE-120) vulnerability in Dlink Go-Rt-Ac750 Firmware. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique NTDS (T1003.003); ranked in the top 1.0% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities 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.

D-Link Go-RT-AC750 routers running firmware GORTAC750_revA_v101b03 and GO-RT-AC750_revB_FWv200b02 contain a buffer overflow vulnerability (CWE-120) reachable through the cgibin hnap_main component. The flaw carries a CVSS 3.1 base score of 9.8 and permits unauthenticated network access that can result in full confidentiality, integrity, and availability impact.

An attacker with network adjacency to an affected device can send crafted requests to the HNAP endpoint without credentials or user interaction, enabling arbitrary code execution or device takeover. The published EPSS score of 0.8048 (peak 0.8291) indicates sustained exploitation interest since disclosure.

D-Link has issued security publication SAP10308 and corresponding bulletins at supportannouncement.us.dlink.com and www.dlink.com/en/security-bulletin/ that address the affected firmware versions.
