Cobbler allows anyone to connect to cobbler XML-RPC server with a known password and make changes
Cobbler, a Linux installation server that allows for rapid setup of network installation environments, has an improper authentication vulnerability starting in version 3.0.0 and prior to versions 3.2.3 and 3.3.7. `utils.get_shared_secret()` always returns `-1`, which allows anyone to connect to cobbler XML-RPC as user `''` password `-1` and make any changes. This gives anyone with network access to a cobbler server full control of the server. Versions 3.2.3 and 3.3.7 fix the issue.
An issue was discovered in Cobbler before 3.3.1. Files in /etc/cobbler are world readable. Two of those files contain some sensitive information that can be exposed to a local user who has non-privileged access to the server. The users.digest file contains the sha2-512 digest of users in a Cobbler local installation. In the case of an easy-to-guess password, it's trivial to obtain the plaintext string. The settings.yaml file contains secrets such as the hashed default password.
An issue was discovered in Cobbler before 3.3.1. In the templar.py file, the function check_for_invalid_imports can allow Cheetah code to import Python modules via the "#from MODULE import" substring. (Only lines beginning with #import are blocked.)
A flaw was found in cobbler software component version 2.6.11-1. It suffers from an invalid parameter validation vulnerability, leading the arbitrary file reading. The flaw is triggered by navigating to a vulnerable URL via cobbler-web on a default installation.
Cobbler version Verified as present in Cobbler versions 2.6.11+, but code inspection suggests at least 2.0.0+ or possibly even older versions may be vulnerable contains a Incorrect Access Control vulnerability in XMLRPC API (/cobbler_api) that can result in Privilege escalation, data manipulation or exfiltration, LDAP credential harvesting. This attack appear to be exploitable via "network connectivity". Taking advantage of improper validation of security tokens in API endpoints. Please note this is a different issue than CVE-2018-10931.
Cobbler version Verified as present in Cobbler versions 2.6.11+, but code inspection suggests at least 2.0.0+ or possibly even older versions may be vulnerable contains a Cross Site Scripting (XSS) vulnerability in cobbler-web that can result in Privilege escalation to admin.. This attack appear to be exploitable via "network connectivity". Sending unauthenticated JavaScript payload to the Cobbler XMLRPC API (/cobbler_api).
It was found that cobbler 2.6.x exposed all functions from its CobblerXMLRPCInterface class over XMLRPC. A remote, unauthenticated attacker could use this flaw to gain high privileges within cobbler, upload files to arbitrary location in the context of the daemon.
Cobbler version up to 2.8.2 is vulnerable to a command injection vulnerability in the "add repo" component resulting in arbitrary code execution as root user.
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.

CVE-2014-3225
Absolute path traversal vulnerability in the web interface in Cobbler 2.4.x through 2.6.x allows remote authenticated users to read arbitrary files via the Kickstart field in a profile.
Incomplete blacklist vulnerability in action_power.py in Cobbler 2.2.0 allows remote attackers to execute arbitrary commands via shell metacharacters in the (1) username or (2) password fields to the power_system method in the xmlrpc API.
template_api.py in Cobbler before 2.0.7, as used in Red Hat Network Satellite Server and other products, does not disable the ability of the Cheetah template engine to execute Python statements contained in templates, which allows remote authenticated administrators to execute arbitrary code via a crafted kickstart template file, a different vulnerability than CVE-2008-6954.
The web interface (CobblerWeb) in Cobbler before 1.2.9 allows remote authenticated users to execute arbitrary Python code in cobblerd by editing a Cheetah kickstart template to import arbitrary Python modules.
