Crítica

VetorAV:N/AC:L/Au:N/C:C/I:C/A:C
Name of the Vulnerable Software and Affected Versions OpenNDS versions prior to 10.1.3
Description An issue was discovered in the captive portal in OpenNDS. The get query function in http microhttpd.c does not validate the length of the query string of GET requests, leading to a buffer overflow. This can result in a Denial-of-Service condition or allow attackers to inject and execute arbitrary bytecode, achieving Remote Code Execution. The issue can be exploited by sending specially crafted GET requests.
Recommendations For OpenNDS versions prior to 10.1.3, update OpenNDS to version 10.2.0 to fix the issue. As a temporary workaround, consider restricting access to the captive portal or disabling the get query function in http microhttpd.c until a patch is available.
