Title: Adcycle AdLibrary.pm Session Access Vulnerability
Severity: HIGH
Description:
Adcycle is a package of perl scripts available from Adcycle.com. The scripts are designed to manage banner ad rotation through a web interface, backended with a MySQL database. This is done by using adcycle as the intermediary software between the HTTP interface, and the MySQL database.
A problem with the Adcycle software could allow remote users to execute arbitrary commands on the SQL database. It may also be possible for a remote user to gain local and possibly administrative access.
The problem occurs in the handling of input by the Adcycle software. Authentication is validated by the AdLibrary.pm script, which accepts input from remote users and compares it against the authentication tables in the database, and currently active users in the database. The scripts, however, do not compare the contents of each transaction with other information that is client/server specific, such as cookie or PID.
Due to the lack of authentication of session specific information, it is possible for a malicious user to create a custom crafted URL, allowing access to the database, the ability to execute SQL commands, and the possibility of gaining local access and elevated privileges on the database.
Affected Products:
- Adcycle.com Adcycle 0.77.0
