CVE-2001-1377 has been classified as a denial of service vulnerability which could potentially lead to system crashes.
To mitigate CVE-2001-1377, update your RADIUS implementation to a version that properly validates the Vendor-Length attribute.
CVE-2001-1377 affects multiple RADIUS implementations including FreeRADIUS, Lucent RADIUS, and several versions of OpenRADIUS and Yard RADIUS.
Yes, CVE-2001-1377 can be exploited remotely, allowing attackers to cause a denial of service by sending specially crafted requests.
Failing to address CVE-2001-1377 may result in service interruptions or crashes, affecting the availability of RADIUS services.
