Several vulnerabilities have been discovered in libphp-adodb, the 'adodb' database abstraction layer for PHP, which is embedded in moodle, a course management system for online learning. The Common Vulnerabilities and Exposures project identifies the following problems:
Andreas Sandblad discovered that improper user input sanitisation results in a potential remote SQL injection vulnerability enabling an attacker to compromise applications, access or modify data, or exploit vulnerabilities in the underlying database implementation. This requires the MySQL root password to be empty. It is fixed by limiting access to the script in question.
A dynamic code evaluation vulnerability allows remote attackers to execute arbitrary PHP functions via the 'do' parameter.
Andy Staudacher discovered an SQL injection vulnerability due to insufficient input sanitising that allows remote attackers to execute arbitrary SQL commands.
GulfTech Security Research discovered multiple cross-site scripting vulnerabilities due to improper user-supplied input sanitisation. Attackers can exploit these vulnerabilities to cause arbitrary scripts to be executed in the browser of an unsuspecting user's machine, or result in the theft of cookie-based authentication credentials.
The old stable distribution (woody) does not contain moodle packages.
For the stable distribution (sarge) these problems have been fixed in version 1.4.4.dfsg.1-3sarge1.
For the unstable distribution these problems will be fixed soon.
We recommend that you upgrade your moodle package.
