Synopsis
The version of Arista Networks EOS running on the remote device is affected by multiple vulnerabilities.Description
The version of Arista Networks EOS running on the remote device is affected by multiple vulnerabilities in the included OpenSSL library :- An information disclosure vulnerability exists in the dsa_sign_setup() function in dsa_ossl.c due to a failure to properly ensure the use of constant-time operations.
An unauthenticated, remote attacker can exploit this, via a timing side-channel attack, to disclose DSA key information. (CVE-2016-2178)
- A vulnerability exists, known as SWEET32, in the 3DES and Blowfish algorithms due to the use of weak 64-bit block ciphers by default. A man-in-the-middle attacker who has sufficient resources can exploit this vulnerability, via a 'birthday' attack, to detect a collision that leaks the XOR between the fixed secret and a known plaintext, allowing the disclosure of the secret text, such as secure HTTPS cookies, and possibly resulting in the hijacking of an authenticated session.
(CVE-2016-2183)
Solution
Contact the vendor for a fixed version. Alternatively, apply the recommended mitigations referenced in the vendor advisory.See Also
