CVE-2014-125112
Description
A vulnerability was identified in Plack::Middleware::Session::Cookie when session data is deserialized from cookies using Storable::thaw. If the secret parameter is not configured or is compromised, an attacker can craft a malicious session cookie containing serialized objects. Because Storable::thaw processes untrusted data without restrictions, this may lead to execution of arbitrary code during object deserialization.
Statement

Understanding the Weakness (CWE)
Confidentiality,Integrity,Availability
Technical Impact: Modify Application Data; Execute Unauthorized Code or Commands
Attackers can easily modify cookies, within the browser or by implementing the client-side code outside of the browser. Reliance on cookies without detailed validation and integrity checking can allow attackers to bypass authentication, conduct injection attacks such as SQL injection and cross-site scripting, or otherwise modify inputs in unexpected ways.
Access Control
Technical Impact: Gain Privileges or Assume Identity
It is dangerous to use cookies to set a user's privileges. The cookie can be manipulated to escalate an attacker's privileges to an administrative level.
