Description:
Citrix has acknowledged a vulnerability in NetScaler, which can be exploited by malicious people to poison the DNS cache.
The vulnerability is caused due to NetScaler not sufficiently randomising the DNS query port number, which can be exploited to poison the DNS cache.
The vulnerability is reported in NetScaler up to and including version 8.1 build 57.3 when recursive DNS caching is activated or the product is running as NAT device in front of a caching DNS server.
Solution:
A fixed version is planned to be released on August, 4th.
