The remote service has multiple denial of service vulnerabilities.
According to its banner, the version of JanaServer running on the
remote host has the following denial of service vulnerabilities :
- The 'http-server' module (TCP port 2506) does not
correctly process requests containing a lot of
occurences of the '%' character, causing it to
consume a large amount of CPU resources.
- The 'pna-proxy' module (TCP port 1090) has an infinite
loop vulnerability when it receives a data block size
larger than the amount of data that is actually sent.
A remote attacker can reportedly freeze the server after fifteen or
more attempts to exploit these vulnerabilities.
