Lifecycle Timeline
6DescriptionCVE.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.
AnalysisAI
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.
Technical ContextAI
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.
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.
