CVE-2013-7489
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe Beaker library through 1.11.0 for Python is affected by deserialization of untrusted data, which could lead to arbitrary code execution.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Beaker library (a session/caching library for Python) through version 1.11.0 contains a deserialization vulnerability where untrusted data is deserialized without proper validation. This unsafe deserialization can be exploited to achieve arbitrary code execution on the host system.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check if Beaker library is installedRun 'pip show beaker' or 'pip list' to see if the Beaker package is present in your Python environmentAffected if Beaker is not installed or the package is not found in your environment
-
Identify the installed Beaker versionRun 'pip show beaker' and look for the Version field, or run Python and execute 'import beaker; print(beaker.__version__)'Affected if The installed version is 1.11.0 or any version lower (for example, 1.10.0, 1.9.0, etc.)
-
Check if Beaker is configured with unsafe serializationInspect your Beaker configuration (in code or configuration files) for session or cache settings that use 'serializer' set to 'pickle' or similar unsafe deserializers. Look for Beaker session or cache creation code that may specify serializer settingsAffected if Beaker is configured to use pickle or another unsafe serializer for session or cache data, and that data originates from untrusted sources
-
Audit code that passes data to Beaker sessions or cacheSearch your application codebase for instances where user-supplied or external data is passed to Beaker session.save() or cache set methods without prior validationAffected if Your application passes untrusted or user-supplied data directly to Beaker session or caching mechanisms without validation
You are affected if Beaker version 1.11.0 or lower is installed AND your application passes untrusted data to Beaker's session or caching serialization mechanisms.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade Beaker to a version newer than 1.11.0 that includes the security fix, and ensure that any data being passed to Beaker's session or caching mechanisms is from trusted sources or properly validated before deserialization.
