Summary

CVE-2025-60554 is a critical-severity Classic Buffer Overflow (CWE-120) vulnerability in Dlink Dir-600L Firmware. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 31th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

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.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2025-60554 is a buffer overflow vulnerability (CWE-120) in D-Link DIR600L Ax firmware version FW116WWb01. It is triggered via the curTime parameter in the formSetEnableWizard function, earning a CVSS v3.1 score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) due to its potential for high-impact confidentiality, integrity, and availability violations.

An unauthenticated remote attacker can exploit this over the network with low complexity by sending a specially crafted request to the vulnerable parameter. Exploitation could result in arbitrary code execution on the device, enabling full control, data exfiltration, configuration changes, or device crashes.

The vulnerability is documented in a GitHub proof-of-concept at https://github.com/luckysmallbird/DLINK-DIR600LAx-Vulnerability/blob/main/08-buffer%20overflow-formSetEnableWizard.md. No official D-Link advisories or patches are referenced; security practitioners should monitor for firmware updates, restrict web interface access via firewalls, and consider device replacement for end-of-life models.

Mitigating Controls (NIST 800-53 r5) AI

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

Input validation directly enforces size checks before buffer copies.

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

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

prevents

Secure coding directly requires bounds-checked memory operations, addressing the root cause of CWE-120.

finds

Security testing in development and acceptance can detect buffer overflows through fuzzing and static analysis, though it does not prevent them at the source.

prevents

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

prevents

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

prevents

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