CVE-2011-4953

Description

From CVE.org

The set_mgmt_parameters function in item.py in cobbler before 2.2.2 allows context-dependent attackers to execute arbitrary code via vectors related to the use of the yaml.load function instead of the yaml.safe_load function, as demonstrated using Puppet.

Statement

This issue did not affect the version of cobbler as shipped with Red Hat Network Satellite Server 5.4 as it did not include the upstream commit d7b30b5fca5097c544ca37ade8c945a3106b1896 that introduced this flaw.

Understanding the Weakness (CWE)

Confidentiality

Technical Impact: Read Files or Directories; Read Application Data

The injected code could access restricted data / files.

Access Control

Technical Impact: Bypass Protection Mechanism

In some cases, injectable code controls authentication; this may lead to a remote vulnerability.

Access Control

Technical Impact: Gain Privileges or Assume Identity

Injected code can access resources that the attacker is directly prevented from accessing.

Integrity,Confidentiality,Availability,Other

Technical Impact: Execute Unauthorized Code or Commands

Code injection attacks can lead to loss of data integrity in nearly all cases as the control-plane data injected is always incidental to data recall or writing. Additionally, code injection can often result in the execution of arbitrary code.

Non-Repudiation

Technical Impact: Hide Activities

Often the actions performed by injected control code are unlogged.
