Synopsis
A database server installed on the remote host is affected by multiple vulnerabilities.
Description
The version of IBM Informix Dynamic Server installed on the remote host is 11.50.xCn prior to 11.50.xC9, 11.70.xCn prior to 11.70.xC9, or 12.10.xCn prior to 12.10.xC8W2. It is, therefore, affected by a multiple vulnerabilities :
- A vulnerability, known as SWEET32, exists in the OpenSSL component 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)
- A remote code execution vulnerability exists in the Open Admin Tool that allows an unauthenticated, remote attacker to execute arbitrary code with administrator privileges. (CVE-2017-1092)
- A denial of service vulnerability exists due to an overflow condition in the FORMAT_UNITS() function caused by improper validation of user-supplied input. An authenticated, remote attacker can exploit this to write large assertion failure files to the server, resulting in a crash of the server. Note that this vulnerability only affects the 12.10 version branch. (CVE-2017-1310)
Solution
Upgrade to IBM Informix Dynamic Server version 11.50.xC9 / 11.70.xC9 / 12.10.xC8W2 or later.
