Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-34108 in the wild and no public exploit code.\n\nAffected product: mailcow-dockerized. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2023-34108/ (Markdown: https://insights.sbomify.com/CVE-2023-34108/index.md)","id":"CVE-2023-34108","markdown":"https://insights.sbomify.com/CVE-2023-34108/index.md","name":"CVE-2023-34108","record":{"aliases":["GHSA-mhh4-qchc-pv22"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["privilege_escalation","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"mail server suite","requires_auth":"low_privilege","summary":"An authenticated attacker can manipulate internal Dovecot variables via crafted passwords, leading to unauthorized access or security control bypasses.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"mailcow\\","vendor":"mailcow"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"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=\u003cvalid-password\u003e\", 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.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Manipulation of Internal Dovecot Variables in mailcow via crafted Passwords","id":"CVE-2023-34108","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2023"},"n_packages":0,"n_references":3,"next":{"headline":"User input results in Unbounded resource consumption in @zxcvbn-ts/core","id":"CVE-2023-34109"},"packages":[],"prev":{"headline":"GLPI vulnerable to unauthorized access to KnowbaseItem data","id":"CVE-2023-34107"},"products":["mailcow-dockerized"],"published":"2023-06-07","related":[{"cvss_score":9.1,"headline":"mailcow: dockerized vulnerable to SSTI in Quota and Quarantine Notification Template","id":"CVE-2025-53909","kev_date_added":null,"published":"2025-07-17"},{"cvss_score":8.8,"headline":"Mailcow Docker Container Exposure to Local Network","id":"CVE-2024-24760","kev_date_added":null,"published":"2024-02-02"},{"cvss_score":8.8,"headline":"OS Command Injection in mailcow","id":"CVE-2022-31138","kev_date_added":null,"published":"2022-07-11"},{"cvss_score":8.8,"headline":"Command injection in n/a","id":"CVE-2022-31245","kev_date_added":null,"published":"2022-05-20"},{"cvss_score":8.8,"headline":"Cross-site request forgery in n/a","id":"CVE-2017-8928","kev_date_added":null,"published":"2017-05-14"},{"cvss_score":8.3,"headline":"mailcow-dockerized XSS Vulnerability in Quarantine UI Allows Unauthorized Access and Data Manipulation","id":"CVE-2023-49077","kev_date_added":null,"published":"2023-11-30"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-01-06","vendors":["mailcow"]},"summary":"An authenticated attacker can manipulate internal Dovecot variables via crafted passwords, leading to unauthorized access or security control bypasses.","url":"https://insights.sbomify.com/CVE-2023-34108/"}
