Impact Analysis

Insecure session ID generation can allow attackers to predict or guess valid session IDs.

This can lead to session hijacking, where an attacker gains unauthorized access to a user's session and potentially sensitive information or functionality.

Such unauthorized access can compromise the confidentiality and integrity of user data and application state.

Executive Summary

This vulnerability affects Maypole versions 2.10 through 2.13 for Perl. It involves the insecure generation of session IDs.

The session ID is created using a seed composed of the system time (which can be obtained from HTTP response headers), a call to the built-in rand() function, and the process ID (PID).

Because these values are predictable or accessible, the session IDs can be guessed or reproduced by an attacker.
