CVE-2023-45579 is a critical-severity Out-of-bounds Write (CWE-787) vulnerability in Dlink Di-7003G Firmware. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Security Account Manager (T1003.002); ranked in the top 31% 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.
A buffer overflow vulnerability affects multiple D-Link router models, specifically DI-7003GV2.D1 versions up to 23.08.25D1, DI-7100G+V2.D1 and DI-7100GV2.D1 up to 23.08.23D1, DI-7200G+V2.D1 and DI-7200GV2.E1 up to 23.08.23E1 or 23.08.23D1, and DI-7300G+V2.D1 plus DI-7400G+V2.D1 up to 23.08.23D1. The flaw, tracked as CWE-787, resides in the jingx.asp function and is triggered by the ip/type parameter, enabling out-of-bounds writes.
An unauthenticated remote attacker can send a crafted HTTP request over the network to exploit the issue, achieving arbitrary code execution with no user interaction required. The vulnerability carries a CVSS 3.1 score of 9.8, reflecting full impact on confidentiality, integrity, and availability.
Public references consist of GitHub reports detailing the buffer overflow but provide no official vendor advisories or patch information. The associated EPSS score has remained in the 0.08–0.09 range with only minor fluctuation since disclosure.
