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.
