CVE-2014-9293

CVSS v2.0

7.5

High

VectorAV:N/AC:L/Au:N/C:P/I:P/A:P
Name of the Vulnerable Software and Affected Versions NTP versions prior to 4.2.7p11 NTP versions 4.2.6p5 and earlier
Description The issue is related to the config auth function in NTP, which generates a cryptographically-weak default key when no authentication key is defined. This makes it easier for remote attackers to defeat cryptographic protection mechanisms via a brute-force attack. The vulnerability can be exploited remotely and may lead to a violation of confidentiality, integrity, and availability of protected information.
Recommendations For NTP versions prior to 4.2.7p11, update to version 4.2.7p11 or later to resolve the issue. For NTP versions 4.2.6p5 and earlier, consider disabling the config auth function until a patch is available. As a temporary workaround, restrict access to the NTP service to minimize the risk of exploitation.
