Base vector

AV:N/AC:L/Au:N/C:P/I:P/A:P

Name of the Vulnerable Software and Affected Versions: Cistron RADIUS daemon (radiusd-cistron) versions 1.6.6 and earlier

Description: The issue allows remote attackers to cause a denial of service and possibly execute arbitrary code via a large value in an NAS-Port attribute. This attribute is interpreted as a negative number, causing a buffer overflow.

Recommendations: For versions 1.6.6 and earlier, update to a version later than 1.6.6 to resolve the issue. As a temporary workaround, consider restricting access to the NAS-Port attribute to minimize the risk of exploitation.
