Summary

CVE-2024-9570 is a high-severity Classic Buffer Overflow (CWE-120) vulnerability in Dlink Dir-619L Firmware. Its CVSS base score is 8.7 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked in the top 14% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

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 vulnerability classified as critical exists in the D-Link DIR-619L B1 firmware version 2.06. It resides in the formEasySetTimezone function of the /goform/formEasySetTimezone endpoint, where improper handling of the curTime argument triggers a buffer overflow (CWE-120). The flaw is remotely reachable and carries a CVSS 4.0 score of 8.7 reflecting high impact on confidentiality, integrity, and availability.

An attacker with low privileges can send a crafted HTTP request to the affected endpoint and trigger the overflow, potentially achieving arbitrary code execution or denial of service on the device. Public proof-of-concept code has already been released, lowering the barrier for exploitation.

Vendor references direct users to D-Link for firmware updates or further guidance, while third-party trackers such as VulDB document the issue and link to the disclosed exploit. No additional mitigation details beyond standard device hardening are provided in the available advisories.

EPSS for this CVE rose from a low baseline to a peak of 0.3514 before receding to the current value of 0.2363, indicating measurable post-disclosure interest in exploitation attempts.

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and analysis can find missing size checks before deployment.

SI-10 Information Input Validation good match

Input validation directly enforces size checks before buffer copies.

SA-8 Security and Privacy Engineering Principles partial match

Engineering principles require bounds checking and safe buffer handling in design.

SI-16 Memory Protection partial match

Memory protection limits the impact of an overflow once it occurs.

prevents

Secure development life cycle mandates processes that can include input validation and bounds checking to prevent buffer overflows.

A.8.26 Application security requirements partial match
prevents

Application security requirements can specify input-size validation and safe buffer handling to mitigate classic buffer overflows.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure system architecture and engineering principles promote defensive coding patterns that reduce the likelihood of unchecked buffer copies.
