CVSS: 7.2EPSS: 0%CPEs: 1EXPL: 0CVE-2021-29439 – Plugins can be installed with minimal admin privileges
https://notcve.org/view.php?id=CVE-2021-29439
The Grav admin plugin prior to version 1.10.11 does not correctly verify caller's privileges. As a consequence, users with the permission `admin.login` can install third-party plugins and their dependencies. By installing the right plugin, an attacker can obtain an arbitrary code execution primitive and elevate their privileges on the instance. The vulnerability has been addressed in version 1.10.11. As a mitigation blocking access to the `/admin` path from untrusted sources will reduce the probability of exploitation. • https://github.com/getgrav/grav-plugin-admin/commit/a220359877fd1281f76ba732e5308e0e3002e4b1 https://github.com/getgrav/grav-plugin-admin/security/advisories/GHSA-wg37-cf5x-55hq • CWE-863: Incorrect Authorization •
CVSS: 9.8EPSS: 84%CPEs: 1EXPL: 3CVE-2021-21425 – Unauthenticated Arbitrary YAML Write/Update leads to Code Execution
https://notcve.org/view.php?id=CVE-2021-21425
Grav Admin Plugin is an HTML user interface that provides a way to configure Grav and create and modify pages. In versions 1.10.7 and earlier, an unauthenticated user can execute some methods of administrator controller without needing any credentials. Particular method execution will result in arbitrary YAML file creation or content change of existing YAML files on the system. Successfully exploitation of that vulnerability results in configuration changes, such as general site information change, custom scheduler job definition, etc. Due to the nature of the vulnerability, an adversary can change some part of the webpage, or hijack an administrator account, or execute operating system command under the context of the web-server user. • https://www.exploit-db.com/exploits/49788 https://github.com/CsEnox/CVE-2021-21425 http://packetstormsecurity.com/files/162283/GravCMS-1.10.7-Remote-Command-Execution.html http://packetstormsecurity.com/files/162457/GravCMS-1.10.7-Remote-Command-Execution.html https://github.com/getgrav/grav-plugin-admin/security/advisories/GHSA-6f53-6qgv-39pj https://pentest.blog/unexpected-journey-7-gravcms-unauthenticated-arbitrary-yaml-write-update-leads-to-code-execution • CWE-284: Improper Access Control •
