Synopsis
The management application running on the remote host is affected by multiple vulnerabilities.Description
According to its self-reported version number, the version of Cisco Prime Security Manager running on the remote host is prior to 9.3.3.2.It is, therefore, affected by multiple vulnerabilities in the bundled NTP libraries :
- A security weakness exists due to the config_auth() function improperly generating default keys when no authentication key is defined in the 'ntp.conf' file.
Key size is limited to 31 bits and the insecure ntp_random() function is used, resulting in cryptographically-weak keys with insufficient entropy.
This allows a remote attacker to defeat cryptographic protection mechanisms via a brute-force attack.
(CVE-2014-9293)
- A security weakness exists due the use of a weak seed to prepare a random number generator used to generate symmetric keys. This allows remote attackers to defeat cryptographic protection mechanisms via a brute-force attack. (CVE-2014-9294)
- Multiple stack-based buffer overflows exist due to improperly validated user-supplied input when handling packets in the crypto_recv(), ctl_putdata(), and configure() functions when using autokey authentication.
This allows a remote attacker, via a specially crafted packet, to cause a denial of service condition or execute arbitrary code. (CVE-2014-9295)
- A unspecified vulnerability exists due to missing return statements in the receive() function, resulting in continued processing even when an authentication error is encountered. This allows a remote attacker, via crafted packets, to trigger unintended association changes. (CVE-2014-9296)
Solution
Upgrade to Cisco Prime Security Manager 9.3.3.2. Note that version 9.3.3.2 is scheduled for release on May 15th, 2015.See Also
