CVE-2009-10007: Catalyst::Plugin::Authentication versions before 0.10_027 for Perl is susceptible to session fixation attacks
Catalyst::Plugin::Authentication versions before 0.10_027 for Perl is susceptible to session fixation attacks.
Catalyst::Plugin::Authentication does not automatically change the session id after authentication. An attacker that obtains a session id cookie can use this to impersonate the victim.
Security readout for executives and security teams
This issue can let someone reuse a victim’s web session after login if a Catalyst application does not rotate the session ID during authentication. The attacker must already obtain or influence the session cookie. Sources do not provide CVSS, confirmed exploitation, or broad product impact. Exposure is most likely in older Perl Catalyst applications using Catalyst::Plugin::Authentication before 0.10_027 and session cookies for authenticated users. The source bundle does not identify CPEs, downstream distributions, or hosted services. Prioritize legacy Catalyst applications that handle customer, admin, or financial sessions. The business risk is account impersonation, but urgency depends on whether affected versions are deployed and whether session ID rotation is absent. Mitigation focus: Upgrade Catalyst::Plugin::Authentication to 0.10_027 or later where applicable.; Ensure authentication flow rotates session IDs immediately after successful login.; Review vendor release notes and project guidance before changing legacy Catalyst behavior..

Session Fixation
Session Fixation represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
