MITRE ATT&CK
1 technique across 1 tactic: Execution The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | D-Link DIR-619L firmware version 2.06B01 with boa web server enabled; requires valid authentication credentials to access /goform/formSchedule endpoint; affects end-of-life unsupported devices only. |
| Impact | This represents a high real-world risk despite no KEV listing. The CVSS 8.8 score reflects network-accessible (AV:N), low complexity (AC:L) attacks requiring only low privileges (PR:L). The exploit is publicly available on GitHub, significantly increasing risk. While EPSS data is not provided, the combination of public exploit code, remote exploitability, and end-of-life status suggests active exploitation is likely. The SSVC framework would classify this as high priority due to: public exploit (E:P), network automatable attack, and high technical impact (complete system compromise). |
| Exploit ScenarioDerived | An attacker with valid low-privilege credentials (or using default credentials if unchanged) can remotely access the router's web interface and send a specially crafted HTTP request to /goform/formSchedule with an oversized curTime parameter. This triggers a stack overflow, allowing arbitrary code execution with the privileges of the boa web server process. The public exploit code available at https://github.com/wudipjq/my_vuln/blob/main/D-Link7/vuln_89/89.md provides a working proof-of-concept, making attacks trivial to execute. |

Alert meAnalysisAIv1 – Mar 15, 2026
Remote code execution in D-Link DIR-619L 2.06B01 results from a stack-based buffer overflow in the formSchedule function when the curTime parameter is manipulated via the /goform/formSchedule endpoint. An authenticated remote attacker can exploit this vulnerability to achieve full system compromise, and public exploit code is currently available. This vulnerability affects only end-of-life devices that no longer receive security updates.
Earlier versions of this analysis (1)
A stack-based buffer overflow vulnerability exists in the formSchedule function of D-Link DIR-619L router firmware version 2.06B01, allowing remote attackers with low privileges to execute arbitrary code by manipulating the curTime parameter. This vulnerability has a publicly available proof-of-concept exploit and affects end-of-life products no longer supported by D-Link, making patching unlikely.
RemediationAI
No official patch is available as D-Link has discontinued support for the DIR-619L series. Immediate mitigation steps include: 1) Replace affected DIR-619L routers with supported models, 2) If replacement is not immediately possible, disable remote administration features and restrict access to the web interface to trusted local networks only, 3) Monitor for suspicious access attempts to /goform/formSchedule endpoints. The D-Link website (https://www.dlink.com/) should be consulted for recommended replacement products.

Technical ContextAI · show details
The vulnerability resides in the boa web server component, specifically in the /goform/formSchedule endpoint of D-Link DIR-619L routers. This is a classic stack-based buffer overflow (CWE-121) where improper boundary checking on the curTime input parameter allows attackers to overwrite stack memory. The CPE identifier (cpe:2.3:a:d-link:dir-619l:*:*:*:*:*:*:*:*) indicates all versions of the DIR-619L firmware are potentially affected, though the specific confirmed vulnerable version is 2.06B01.

Lifecycle Timeline
3DescriptionCVE.org
A security flaw has been discovered in D-Link DIR-619L 2.06B01. The affected element is the function formSchedule of the file /goform/formSchedule of the component boa. Performing a manipulation of the argument curTime results in stack-based buffer overflow. The attack may be initiated remotely. The exploit has been released to the public and may be used for attacks. This vulnerability only affects products that are no longer supported by the maintainer.
Executive ViewAI
D-Link DIR-619L routers running firmware 2.06B01 are vulnerable to remote code execution through a stack buffer overflow, with public exploits now available. Organizations using these end-of-life devices face immediate risk of compromise, as the vendor will not release patches. This affects network perimeter security and any systems relying on these devices for connectivity or traffic management.
Network segmentation: restrict access to affected devices using firewall rules and ACLs; disable remote management features (telnet, SSH, HTTP/HTTPS access) if not operationally required; place devices behind a WAF or IPS configured to block malicious formSchedule requests with suspicious curTime parameters; monitor for exploitation attempts targeting /goform/formSchedule endpoint; consider blocking WAN access entirely and limiting to trusted LAN sources only. Note: These are temporary measures only—device replacement is mandatory.
