Cross references: php - --------------------------------------------------------------------- 1. Topic: The GUI portion of Piranha may allow any remote attacker to execute commands on the server. This may lead to remote compromise of the server, as well as exposure or defacement of the website. 2. Relevant releases/architectures: Red Hat Linux 6.2 - i386 alpha sparc 3. Problem description: Piranha when it is installed generates a 'secure' web interface ID using the HTML .htaccess method. The information for the account is placed in /home/httpd/html/piranha/secure/passwords which was supposed to be released with a blank password. In fact the password that is actually on the CD is either 'q' or 'piranha'. It was intended that when the administrator loaded the piranha package onto their box, that it was their resonsibility to change that password. This is not a hidden account. It is meerly used to protect the web pages from unauthorized access. The security problem arises from the /home/httpd/html/piranha/secure/passwd.php3 file from which it is possible to execute commands by inserting them into the change password option eg entering 'blah;/bin/command to execute' into the field, and again to verify, everything after the semicolon is executed with the same privilege as the webserver. It is possible at this point to compromise the webserver or do serious damage to the site. 4. Solution: For each RPM for your particular architecture, run: rpm -Fvh [filename] where filename is the name of the RPM. Temporarily, you should set a password on the web pages as should be done when you first install the package for the sake of speed you can issue the following command htpasswd -c -b /home/httpd/html/piranha/secure/passwords piranha 'password of choice' In theory, this means only you have access to that area and you are hardly likely to try and exploit the problem yourself. When you install the update for the piranha-gui, please take a moment to login into the gui frontend and set a password on the account (http://localhost/piranha) 5.

Our key is available at: http://www.redhat.com/corp/contact.html You can verify each package with the following command: rpm --checksig <filename> If you only wish to verify that each package has not been corrupted or tampered with, examine only the md5sum with the following command: rpm --checksig --nogpg <filename> 10.
