Ajenti: Privilege escalation to root via unauthenticated/unauthorized plugin install task

Ajenti is a Linux & BSD modular server admin panel. Prior to version 2.2.16, any authenticated user can call /api/core/tasks/start to enqueue InstallPlugin, UnInstallPlugin, or UpgradeAll from plugins/plugins/tasks.py without plugin-management authorization. InstallPlugin and UnInstallPlugin construct a pip package specification from unvalidated name and version fields, and the task worker invokes pip while running as root. A low-privileged user can therefore select or manipulate a package installed with root privileges and can install, remove, or upgrade plugins without administrative permission, resulting in root code execution and full host compromise. This issue is fixed in version 2.2.16.

Missing Anti‑Frame Header Vulnerability in Ajenti UI Allows Clickjacking

ajenti through v2.2.13 has a clickjacking weakness in the browser-facing login and administrative UI. In ajenti-core/aj/http.py, the core HTTP response path initializes an empty header list, forwards handler-added headers verbatim, and finalizes responses through WSGI start_response() without adding anti-framing protections such as X-Frame-Options or a Content-Security-Policy frame-ancestors restriction.

Ajenti 2.1.36 Authenticated Remote Code Execution

Ajenti 2.1.36 contains a post-authenticated remote command execution vulnerability that allows remote attackers to execute arbitrary commands after successful login. Attackers can leverage the /api/terminal/create endpoint to send a netcat reverse shell payload targeting a specified IP and port.

Password bypass when 2FA is activated

ajenti.plugin.core defines all necessary core elements to allow Ajenti to run properly. Prior to 0.112, if the 2FA was activated, it was possible to bypass the password authentication This vulnerability is fixed in 0.112.

ajenti.plugin.core has a race conditions in 2FA

ajenti.plugin.core defines all necessary core elements to allow Ajenti to run properly. Prior to 0.112, if the 2FA was activated, it was possible during a short moment after the authentication of an user to bypass its authentication. This vulnerability is fixed in 0.112.

Ajenti has an authorization bypass during custom package installation

Ajenti is a Linux and BSD modular server admin panel. Prior to 2.2.15, an authenticated user (using the auth_users plugin authentication method) could install a custom package even if this user is not superuser. This vulnerability is fixed in 2.2.15.

Ajenti has a potential Remote Code Execution

Ajenti is a Linux and BSD modular server admin panel. Prior to version 2.2.13, an unauthenticated user could gain access to a server to execute arbitrary code on this server. This is fixed in the version 2.2.13.

A vulnerability has been found in ajenti 2.1.31 and classified as critical. This vulnerability affects unknown code of the component API. The manipulation leads to privilege escalation. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used. Upgrading to version 2.1.32 is able to address this issue. The name of the patch is 7aa146b724e0e20cfee2c71ca78fafbf53a8767c. It is recommended to upgrade the affected component.

Cross-site scripting (XSS) vulnerability in plugins/main/content/js/ajenti.coffee in Eugene Pankov Ajenti 1.2.13 allows remote authenticated users to inject arbitrary web script or HTML via the command field in the Cron functionality.

Multiple cross-site scripting (XSS) vulnerabilities in the respond_error function in routing.py in Eugene Pankov Ajenti before 1.2.21.7 allow remote attackers to inject arbitrary web script or HTML via the PATH_INFO to (1) resources.js or (2) resources.css in ajenti:static/, related to the traceback page.

ajenticp (aka Ajenti Docker control panel) for Ajenti through v1.2.23.13 has XSS via a filename that is mishandled in File Manager.

Ajenti version 2 contains an Information Disclosure vulnerability in Line 176 of the code source that can result in user and system enumeration as well as data from the /etc/ajenti/config.yml file. This attack appears to be exploitable via network connectivity to the web application.

Ajenti version version 2 contains a Improper Error Handling vulnerability in Login JSON request that can result in The requisition leaks a path of the server. This attack appear to be exploitable via By sending a malformed JSON, the tool responds with a traceback error that leaks a path of the server.

Ajenti version version 2 contains a Cross ite Request Forgery (CSRF) vulnerability in the command execution panel of the tool used to manage the server. that can result in Code execution on the server . This attack appear to be exploitable via Being a CSRF, victim interaction is needed, when the victim access the infected trigger of the CSRF any code that match the victim privledges on the server can be executed..

Ajenti version version 2 contains a Input Validation vulnerability in ID string on Get-values POST request that can result in Server Crashing. This attack appear to be exploitable via An attacker can freeze te server by sending a giant string to the ID parameter ..

Ajenti version version 2 contains a Insecure Permissions vulnerability in Plugins download that can result in The download of any plugins as being a normal user. This attack appear to be exploitable via By knowing how the requisition is made, and sending it as a normal user, the server, in response, downloads the plugin.
