SA15388

VERIFY ADVISORY:
http://secunia.com/advisories/15388/

CRITICAL:
Moderately critical

IMPACT:
Security Bypass, DoS

WHERE:
>From remote

SOFTWARE:
ignitionServer 0.1.x
http://secunia.com/product/3123/
ignitionServer 0.2.x
http://secunia.com/product/3124/
ignitionServer 0.3.x
http://secunia.com/product/3565/

DESCRIPTION:
Two vulnerabilities have been reported in ignitionServer, which can
be exploited by malicious users to delete access entries or prevent
protected operators from accessing certain channels.

1) According to the IRCX draft, only owners are allowed to delete
access entries set by owners. However, this is not checked before
access entries are deleted, which breaches channel security and
allows hosts to delete access entries set by owners.

2) Due to a design error, protected IRC operators can't access
channels created and locked by normal users.

SOLUTION:
The vulnerabilities have been fixed in version 0.3.6-P1.
