Summary

  • Multiple Cisco products incorporate a version of the ntpd package. Versions of this package are affected by one or more vulnerabilities that could allow an unauthenticated, remote attacker to execute arbitrary code or create a denial of service (DoS) condition.

    On December 19, 2014, NTP.org and US-CERT released security advisories detailing two issues regarding weak cryptographic pseudorandom number generation (PRNG), three buffer overflow vulnerabilities, and an unhandled error condition with an unknown impact. These vulnerabilities are referenced in this document as follows:
    • CVE-2014-9293: Weak Default Key in config_auth()
    • CVE-2014-9294: Noncryptographic Random Number Generator with Weak Seed Used by ntp-keygen to Generate Symmetric Keys
    • CVE-2014-9295: Multiple Buffer Overflow Vulnerabilities in ntpd
    • CVE-2014-9296: ntpd receive(): Missing Return on Error

    On February 4, 2015, NTP.org and US-CERT released two additional vulnerabilities regarding improper validation of vallen in ntp_crypto.c and an IPv6 ::1 ACL bypass vulnerability. These vulnerabilities were added to their original advisory. For completeness, these vulnerabilities are referenced in this document as follows:
    • CVE-2014-9297: NTP ntp_crypto.c Improper Validation Vulnerability
    • CVE-2014-9298: NTP IPv6 ACL Bypass Vulnerability

    This advisory will be updated as additional information becomes available.

    Cisco will release software updates that address these vulnerabilities.

    Workarounds that mitigate these vulnerabilities are available.

    This section will continue to be populated when investigation of each product has concluded.

    No other Cisco products are currently known to be affected by these vulnerabilities.

Details

  • On December 19, 2014, NTP.org and US-CERT released security advisories for ntpd detailing two issues regarding weak cryptographic pseudorandom number generation (PRNG), three buffer overflow vulnerabilities, and an unhandled error condition with an unknown impact. Further, on February 4, 2015, these advisories were updated to include an autokey authentication vulnerability and an IPv6 ACL bypass vulnerability.

    The impact of these vulnerabilities on Cisco products may vary depending on the affected product.

    For Cisco products, refer to the information provided in the Cisco bug IDs listed in the "Affected Products" section of this document.

    Additional information and detailed instructions are available in the Cisco installation, configuration, and maintenance guides for each product. If additional clarification or advice is needed, please contact your support organization.

    The vulnerability names and associated Common Vulnerabilities and Exposures (CVE) IDs are as follows:
    • Weak Default Key in config_auth()

      • An issue in the generation of a random key for ntpd could allow an unauthenticated, remote attacker to guess the generated key. The attacker may be able to use it to send ntpdc query or configuration requests.

      The issue occurs because ntpd automatically generates weak keys if no ntpdc request authentication key was specified in the ntp.conf configuration file. An attacker could exploit this issue by guessing the generated key and matching any configured IP restrictions. An exploit could allow the attacker to send ntpdc query or configuration requests.

      This issue has been assigned CVE ID CVE-2014-9293.

      The Cisco Product Security Incident Response Team (PSIRT) considers this a hardening issue rather than a vulnerability.

    • Noncryptographic Random Number Generator with Weak Seed Used by ntp-keygen to Generate Symmetric Keys

      • An issue in ntp-keygen of ntpd could allow an unauthenticated, remote attacker to guess the generated MD5 keys.

      The issue occurs because ntp-keygen uses a weak method for generating the MD5 keys. An attacker could exploit this issue by guessing the generated MD5 keys. An exploit could allow the attacker to use the guessed MD5 keys to spoof a trusted NTP client or server.

      This issue has been assigned CVE ID CVE-2014-9294.

      Cisco PSIRT considers this a hardening issue rather than a vulnerability.

    • Multiple Buffer Overflow Vulnerabilities in ntpd

      • Vulnerabilities in crypto_recv(), ctl_putdata(), and configure() of ntpd could allow an unauthenticated, remote attacker to cause a stack buffer overflow, which could allow the attacker to execute malicious code with the privilege level of the ntpd process.

      The vulnerabilities are due to incorrect validation checks on the received packets. An attacker could exploit these vulnerabilities by sending crafted request packets. An exploit could allow the attacker to crash the ntpd process. Arbitrary code execution with the privilege level of the ntpd process may also be possible.

      This vulnerability has been assigned CVE ID CVE-2014-9295.

    • ntpd receive(): Missing Return on Error

      • An issue in ntp_proto.c:receive() of ntp in the code path where an error was detected could indicate processing did not stop when a specific rare error occurs.

      The issue is due to a missing return; in the code path where an error was detected. It has not been proven how an attacker could exploit this issue. The impact to the affected system is also unknown.

      This issue has been assigned CVE ID CVE-2014-9296.

      Cisco PSIRT at this stage does not consider this to be a vulnerability.

    • NTP ntp_crypto.c Improper Validation Vulnerability

      • A vulnerability in ntp_crypto.c of ntpd could allow an unauthenticated, remote attacker to obtain sensitive information.

      The vulnerability is due to improper validation of vallen. An attacker could exploit this vulnerability by sending crafted packets to a device running ntpd and configured with autokey authentication. An exploit could allow the attacker to retrieve sensitive information.

      This issue has been assigned CVE ID CVE-2014-9297.

    • NTP IPv6 ACL Bypass Vulnerability

      • A vulnerability in IPv6 address handling could allow an unauthenticated, remote attacker to send IPv6 network packets to a vulnerable system using a spoofed source address of ::1 on an interface not configured for localhost.

      The vulnerability is due to improper IPv6 address processing. An attacker could exploit this issue by sending IPv6 packets with a source address of ::1 to an affected host. An exploit could allow the attacker to bypass application ACLs that rely on IPv6 source address filtering.

      This issue has been assigned CVE ID CVE-2014-9298

Workarounds

  • Mitigations involve preventing the device from processing NTP control queries. In products that allow for editing the ntp.conf file, this is accomplished by the restrict directive. Other products may support ntp access-group commands which can be used to filter NTP control queries. Potential workarounds for each affected Cisco product is referenced in the Cisco Bug ID workarounds section.

    Mitigations that can be deployed on Cisco devices in a network are available in the Cisco Applied Intelligence companion document for this advisory:
    http://tools.cisco.com/security/center/viewAMBAlert.x?alertId=36857

Fixed Software

  • When considering software upgrades, customers are advised to consult the Cisco Security Advisories, Responses, and Notices archive at http://www.cisco.com/go/psirt and review subsequent advisories to determine exposure and a complete upgrade solution.

    In all cases, customers should ensure that the devices to be upgraded contain sufficient memory and confirm that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, customers are advised to contact the Cisco Technical Assistance Center (TAC) or their contracted maintenance providers.

    This section will be populated when investigation of each product has concluded.

Exploitation and Public Announcements

  • Cisco PSIRT is not aware of any public announcements or malicious use of the vulnerabilities described in this advisory.

    These vulnerabilities were reported to Cisco by US-CERT/CC.
