============================================= INTERNET SECURITY AUDITORS ALERT 2013-009 - Original release date: March 15th, 2013 - Last revised: June 4th, 2013 - Discovered by: Manuel Garcia Cardenas - Severity: 4,8/10 (CVSS Base Score) - CVE-ID: CVE-2013-2621, CVE-2013-2623, CVE-2013-2624 =============================================
Multiple Vulnerabilities in Telaen <= 1.3.0
Telaen is a webmail reader application supporting both IMAP and POP3 protocols. It can be installed without dependence of any PHP's extra modules or a separate database. It is Open source software published under GNU General Public License (GPL).
The last version of Telaen is 1.3.0 released on January 2012.
Telaen 1.3.0 and lower versions contain a flaw that allows a remote redirection attack. This flaw exists because the application does not properly sanitise the file "redir.php". This allows an attacker to create a specially crafted URL, that if clicked, would redirect a victim from the intended legitimate web site to an arbitrary web site of the attacker's choice.
Due to the errors caused by the application Telaen 1.3.0 and lower versions, we can display the full webapp installation path.
FULL PATH DISCLOSURE: http://vulnerablesite.com/telaen/inc/init.php
REDIRECT: An attacker can redirect any user to any malicious website. Below I have mentioned the vulnerable URL.
FULL PATH DISCLOSURE: An attacker can obtain the full path to the applitation and if the webroot is getting leaked, attackers may abuse the knowledge and use it in combination with file inclusion vulnerabilites to steal configuration files regarding the web application or the rest of the operating system.
Versions of Telaen < v1.3.1.
REDIRECT AND XSS: All data received by the application and can be modified by the user, before making any kind of transaction with them must be validated.
FULL PATH DISCLOSURE: Turn off display errors in the configuration and unify the error pages.
