Cockpit: cockpit: unauthorized modification of login records via integer overflow
A flaw was found in Cockpit. An authenticated local user with a large user identifier (UID) can cause unauthorized modification and disclosure of login records. On 32-bit systems, an integer overflow during session accounting allows the user's login process to read or overwrite the legacy log entries of other accounts.

Publicación ActualizaciónCockpit: cockpit: denial of service in `cockpit-ws` due to url-root handling without a trailing slash
A flaw was found in `cockpit-ws`. This vulnerability allows a remote, unauthenticated attacker to cause a Denial of Service (DoS) by sending a specially crafted request. When the `WebService.UrlRoot` is configured and a request is made to the exact URL-root prefix without a trailing slash, `cockpit-ws` can terminate unexpectedly. This issue leads to the unavailability of the Cockpit web service.

Publicación ActualizaciónCockpit: cockpit: denial of service via unbounded connection thread spawning
A flaw was found in Cockpit. An unauthenticated remote attacker can exploit this vulnerability by initiating and sustaining numerous simultaneous connections to the `cockpit-tls` service. This forces the service to create an unbounded number of detached threads, consuming system resources such as memory and file descriptors. The primary consequence is a denial of service (DoS), leading to degradation or complete unavailability of the Cockpit service for legitimate users.

Publicación ActualizaciónCockpit-ws: cockpit: cockpit-ws: unauthenticated remote memory leak via cockpitlang cookie in send_login_html
A memory leak flaw was found in cockpit-ws. The login page handler leaks a heap allocation on every unauthenticated request that carries a CockpitLang cookie, allowing a remote unauthenticated attacker to exhaust memory on the host and cause a denial of service.

Publicación ActualizaciónCockpit: cockpit: arbitrary command execution via crafted links in system logs ui
A flaw was found in Cockpit. This vulnerability allows a remote attacker to achieve arbitrary command execution on the host by exploiting unsanitized user-controlled parameters within crafted links in the system logs user interface (UI). An attacker can inject shell metacharacters and command substitutions into these parameters, leading to the execution of arbitrary shell commands on the affected system. This could result in a complete system compromise.

Publicación ActualizaciónCockpit: cockpit: unauthenticated remote code execution due to ssh command-line argument injection
Cockpit's remote login feature passes user-supplied hostnames and usernames from the web interface to the SSH client without validation or sanitization. An attacker with network access to the Cockpit web service can craft a single HTTP request to the login endpoint that injects malicious SSH options or shell commands, achieving code execution on the Cockpit host without valid credentials. The injection occurs during the authentication flow before any credential verification takes place, meaning no login is required to exploit the vulnerability.

Publicación ActualizaciónCockpit: authenticated user can kill any process when enabling pam_env's user_readenv option
A flaw was found in the cockpit package. This flaw allows an authenticated user to kill any process when enabling the pam_env's user_readenv option, which leads to a denial of service (DoS) attack.

Publicación ActualizaciónCockpit: command injection when deleting a sosreport with a crafted name
A flaw was found in Cockpit. Deleting a sosreport with a crafted name via the Cockpit web interface can lead to a command injection vulnerability, resulting in privilege escalation. This issue affects Cockpit versions 270 and newer.

Publicación ActualizaciónCVE-2021-3698
A flaw was found in Cockpit in versions prior to 260 in the way it handles the certificate verification performed by the System Security Services Daemon (SSSD). This flaw allows client certificates to authenticate successfully, regardless of the Certificate Revocation List (CRL) configuration or the certificate status. The highest threat from this vulnerability is to confidentiality.

Publicación ActualizaciónCVE-2021-3660
Cockpit (and its plugins) do not seem to protect itself against clickjacking. It is possible to render a page from a cockpit server via another website, inside an <iFrame> HTML entry. This may be used by a malicious website in clickjacking or similar attacks.

Publicación ActualizaciónCVE-2019-3804
It was found that cockpit before version 184 used glib's base64 decode functionality incorrectly resulting in a denial of service attack. An unauthenticated attacker could send a specially crafted request with an invalid base64-encoded cookie which could cause the web service to crash.
