CVE-2013-7489
Description
A flaw was found in python-beaker, where it is affected by the deserialization of untrusted data. This flaw allows an attacker to enter malicious payloads into the cache database (for example, if they are on the network and have credentials for the database), to perform remote code execution on the machine running Beaker, due to the deserialization of data from the cache database by Pickle.
Mitigation
Implementing proper access control on the Beaker cache database, to prevent unauthorized writes into the database, will mitigate exploitation of this flaw. This flaw also cannot be triggered if the Cache functionality of Beaker is not used. When using the Session feature of Beaker, use the signing functionality to verify the integrity of the data retrieved from the database before deserialization.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
