Subject: Re: CVE Request -- Multiple security issues in various versions of AWStats
Jan!
Petr was not right :-). And I CCed this letter, to let him know about it.
1. As I wrote in my previous letter there is CVE entry already for
Redirector vulnerability - Open redirect vulnerability
(http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2009-5020). And as I
showed in my advisory in case of #2, this fix can be bypassed, so there can
be made update for this CVE entry or made new entry.
So CVE, Mitre and all others, who made such entries in their vulnerability
databases (including developer, who tried to fix it, but incorrectly and it
can be bypassed) already recognized it as vulnerability.
2. Yes, awredir.pl is url redirector and it's only one thing that it should
do, but in result we have 7 holes: 3 XSS, 1 SQLi, 1 HTTPRS, 1 CLRFi and one
Redirector hole (even redirecting should be done flawless). To which holes
redirectors can lead I wrote in my article Redirectors: the phantom menace.
3. Petr and everyone who don't know about Redirector vulnerabilities should
read articles about this type of holes:
URL Redirector Abuse (WASC-38) in WASC 2.0
http://projects.webappsec.org/w/page/13246981/URL%20Redirector%20Abuse
And my articles (first one on Ukrainian and others are on English):
Redirectors (I wrote this article, with few examples of redirectors, before
I posted multiple redirector vulnerabilities in search engines in my 2007's
project Month of Search Engines Bugs)
http://websecurity.com.ua/987/
Redirectors: the phantom menace
http://websecurity.com.ua/3495/
Attacks via closed redirectors
http://websecurity.com.ua/3531/
P.S.
Since you wrote me, then you can listen my music.
In September I've released my first commercial album Originality
(http://soundcloud.com/mustlive/sets/originality). And soon I'll release my
new single. So you can listen these and other my compositions ;-). I hope
you'll enjoy my music.
