DESCRIPTION:
Kacper Szczesniak has discovered a vulnerability in Gadu-Gadu, which
can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to an error when processing certain
HTML content and can be exploited to inject malicious content via a
Man-in-the-Middle (MitM) attack and execute an arbitrary program.
Successful exploitation allows execution of arbitrary code, but
requires intercepting the communication between the client and
certain web servers.
The vulnerability is confirmed in version 10.5. Other versions may
also be affected.
SOLUTION:
Filter malicious characters and character sequences in a proxy.
