Improper Authorization in cobbler/cobbler

Improper Authorization in GitHub repository cobbler/cobbler prior to 3.3.2.

• Auf 2.4.1-0ubuntu2+esm1 aktualisieren

CVE-2021-45083

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.

CVE-2021-45081

An issue was discovered in Cobbler through 3.3.1. Routines in several files use the HTTP protocol instead of the more secure HTTPS.

CVE-2021-45082

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.)

• Auf 2.4.1-0ubuntu2+esm1 aktualisieren

CVE-2021-40325

Cobbler before 3.3.0 allows authorization bypass for modification of settings.

• Auf 2.4.1-0ubuntu2+esm1 aktualisieren

CVE-2021-40324

Cobbler before 3.3.0 allows arbitrary file write operations via upload_log_data.

• Auf 2.4.1-0ubuntu2+esm1 aktualisieren

CVE-2021-40323

CVE-2018-1000226

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.

• Auf 2.4.1-0ubuntu2+esm1 aktualisieren

CVE-2018-1000225

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).

• Auf 2.4.1-0ubuntu2+esm1 aktualisieren

CVE-2018-10931

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.

• Auf 2.4.1-0ubuntu2+esm1 aktualisieren

CVE-2017-1000469

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.

• Auf 2.4.1-0ubuntu2+esm1 aktualisieren
