CVE-2022-31138 WRITEUP HIGH WRITEUP
mailcow <2022-06a - Privilege Escalation
mailcow is a mailserver suite. Prior to mailcow-dockerized version 2022-06a, an extended privilege vulnerability can be exploited by manipulating the custom parameters regexmess, skipmess, regexflag, delete2foldersonly, delete2foldersbutnot, regextrans2, pipemess, or maxlinelengthcmd to execute arbitrary code. Users should update their mailcow instances with the `update.sh` script in the mailcow root directory to 2022-06a or newer to receive a patch for this issue. As a temporary workaround, the Syncjob ACL can be removed from all mailbox users, preventing changes to those settings.
CVSS 8.8
CVE-2024-24760 WRITEUP HIGH WRITEUP
mailcow <2024-01c - Info Disclosure
mailcow is a dockerized email package, with multiple containers linked in one bridged network. A security vulnerability has been identified in mailcow affecting versions < 2024-01c. This vulnerability potentially allows attackers on the same subnet to connect to exposed ports of a Docker container, even when the port is bound to 127.0.0.1. The vulnerability has been addressed by implementing additional iptables/nftables rules. These rules drop packets for Docker containers on ports 3306, 6379, 8983, and 12345, where the input interface is not `br-mailcow` and the output interface is `br-mailcow`.
CVSS 8.8
CVE-2024-41958 WRITEUP MEDIUM WRITEUP
mailcow < 2024-07 - Authenticated Two-Factor Authentication Bypass
mailcow: dockerized is an open source groupware/email suite based on docker. A vulnerability has been discovered in the two-factor authentication (2FA) mechanism. This flaw allows an authenticated attacker to bypass the 2FA protection, enabling unauthorized access to other accounts that are otherwise secured with 2FA. To exploit this vulnerability, the attacker must first have access to an account within the system and possess the credentials of the target account that has 2FA enabled. By leveraging these credentials, the attacker can circumvent the 2FA process and gain access to the protected account. This issue has been addressed in the `2024-07` release. All users are advised to upgrade. There are no known workarounds for this vulnerability.
CVSS 6.6
CVE-2023-34108 WRITEUP HIGH WRITEUP
mailcow - Authenticated Dovecot Variable Injection via Crafted Password
mailcow is a mail server suite based on Dovecot, Postfix and other open source software, that provides a modern web UI for user/server administration. A vulnerability has been discovered in mailcow which allows an attacker to manipulate internal Dovecot variables by using specially crafted passwords during the authentication process. The issue arises from the behavior of the `passwd-verify.lua` script, which is responsible for verifying user passwords during login attempts. Upon a successful login, the script returns a response in the format of "password=<valid-password>", indicating the successful authentication. By crafting a password with additional key-value pairs appended to it, an attacker can manipulate the returned string and influence the internal behavior of Dovecot. For example, using the password "123 mail_crypt_save_version=0" would cause the `passwd-verify.lua` script to return the string "password=123 mail_crypt_save_version=0". Consequently, Dovecot will interpret this string and set the internal variables accordingly, leading to unintended consequences. This vulnerability can be exploited by an authenticated attacker who has the ability to set their own password. Successful exploitation of this vulnerability could result in unauthorized access to user accounts, bypassing security controls, or other malicious activities. This issue has been patched in version `2023-05a`. Users are advised to upgrade. There are no known workarounds for this vulnerability.
CVSS 8.8
CVE-2024-23824 WRITEUP MEDIUM WRITEUP
mailcow < 2024-01 - Denial of Service via Pixel Flood Attack
mailcow is a dockerized email package, with multiple containers linked in one bridged network. The application is vulnerable to pixel flood attack, once the payload has been successfully uploaded in the logo the application goes slow and doesn't respond in the admin page. It is tested on the versions 2023-12a and prior and patched in version 2024-01.
CVSS 4.7
CVE-2024-41959 WRITEUP HIGH WRITEUP
mailcow < 2024-07 - Unauthenticated Stored Cross-Site Scripting via API Log Injection
mailcow: dockerized is an open source groupware/email suite based on docker. An unauthenticated attacker can inject a JavaScript payload into the API logs. This payload is executed whenever the API logs page is viewed, potentially allowing an attacker to run malicious scripts in the context of the user's browser. This could lead to unauthorized actions, data theft, or further exploitation of the affected system. This issue has been addressed in the `2024-07` release. All users are advised to upgrade. There are no known workarounds for this vulnerability.
CVSS 7.6
CVE-2024-41960 WRITEUP LOW WRITEUP
mailcow < 2024-07 - Authenticated Stored Cross-Site Scripting via Relay Hosts Configuration
mailcow: dockerized is an open source groupware/email suite based on docker. An authenticated admin user can inject a JavaScript payload into the Relay Hosts configuration. The injected payload is executed whenever the configuration page is viewed, enabling the attacker to execute arbitrary scripts in the context of the user's browser. This could lead to data theft, or further exploitation. This issue has been addressed in the `2024-07` release. All users are advised to upgrade. There are no known workarounds for this vulnerability.
CVSS 3.8
CVE-2025-53909 WRITEUP CRITICAL WRITEUP
mailcow: dockerized <2025-07 - SSTI
mailcow: dockerized is an open source groupware/email suite based on docker. A Server-Side Template Injection (SSTI) vulnerability exists in versions prior to 2025-07 in the notification template system used by mailcow for sending quota and quarantine alerts. The template rendering engine allows template expressions that may be abused to execute code in certain contexts. The issue requires admin-level access to mailcow UI to configure templates, which are automatically rendered during normal system operation. Version 2025-07 contains a patch for the issue.
