Title: K9 Web Protection Authentication Bypass Vulnerabilities

Severity: MODERATE

Description:

K9 Web Protection is a web-based application to filter content on home computers.

The application is prone to multiple authentication-bypass vulnerabilities. Specifically, an attacker can disable execution of JavaScript in the browser and access the following admin pages locally:

http://127.0.0.1:2372/summary
http://127.0.0.1:2372/detail
http://127.0.0.1:2372/overrides
http://127.0.0.1:2372/pwemail

The attacker can exploit these issues to gain unauthorized access to the affected application; other attacks are also possible.

K9 Web Protection 4.0.230 Beta is vulnerable; other versions may also be affected.

Affected Products:

  • Blue Coat Systems K9 Web Protection 4.0.230 Beta
