CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2023-37791 is a critical-severity Out-of-bounds Write (CWE-787) vulnerability in Dlink Dir-619L 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 4% 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.
D-Link DIR-619L firmware version 2.04(TW) contains a stack-based buffer overflow in the web management interface at the /goform/formLogin endpoint, triggered by the curTime parameter. The flaw is tracked as CVE-2023-37791 with a CVSS 3.1 score of 9.8 and is classified under CWE-787 as an out-of-bounds write.
An unauthenticated attacker with network access can supply a crafted curTime value to overwrite the stack, enabling remote code execution, denial of service, or full device compromise without any user interaction or credentials.
D-Link has published a security bulletin addressing the issue, and public proof-of-concept code demonstrating the overflow has been released on GitHub. The EPSS score rose from lower values to a peak of 0.2862 before receding to the current 0.1482, indicating a period of increased exploitation interest after disclosure.
