CWE ID Description
CWE-119 The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
CWE-121 A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).

AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability is a stack-based buffer overflow found in the sprintf function of the /goform/formLanSetupRouterSettings component in the Boa Webserver used by D-Link DIR-513 1.0. It occurs due to manipulation of the argument curTime, allowing an attacker to remotely exploit the issue.


How can this vulnerability impact me? :

The vulnerability can lead to a critical security breach, potentially allowing remote attackers to execute arbitrary code or cause a denial of service on affected devices. Since it is a stack-based buffer overflow, it can compromise the integrity, confidentiality, and availability of the system.


What immediate steps should I take to mitigate this vulnerability?

Since the affected products are no longer supported by the maintainer, immediate mitigation steps include discontinuing use of the vulnerable D-Link DIR-513 device or isolating it from the network to prevent remote exploitation. Additionally, monitor network traffic for suspicious activity targeting the /goform/formLanSetupRouterSettings endpoint of the Boa Webserver and consider deploying network-level protections such as firewalls or intrusion prevention systems to block exploit attempts.
