An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-39830 in the wild and no public exploit code.\n\nAffected product: Mattermost Mattermost. 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-2024-39830/ (Markdown: https://insights.sbomify.com/CVE-2024-39830/index.md)","id":"CVE-2024-39830","markdown":"https://insights.sbomify.com/CVE-2024-39830/index.md","name":"CVE-2024-39830","record":{"aliases":["GHSA-vmvm-jjvw-qwpw"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Mattermost collaboration platform","requires_auth":"none","summary":"Attackers can retrieve remote cluster tokens via timing attacks when shared channels are enabled, potentially bypassing authentication.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Mattermost","cpe":[{"product":"mattermost","vendor":"mattermost"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-203","name":"Observable Discrepancy"},{"id":"CWE-287","name":"Improper Authentication"}],"description":"Mattermost versions 9.8.x \u003c= 9.8.0, 9.7.x \u003c= 9.7.4, 9.6.x \u003c= 9.6.2 and 9.5.x \u003c= 9.5.5, when shared channels are enabled, fail to use constant time comparison for remote cluster tokens which allows an attacker to retrieve the remote cluster token via a timing attack during remote cluster token comparison.","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":"Timing attack during remote cluster token comparison when shared channels are enabled","id":"CVE-2024-39830","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"mattermost:mattermost","products":["mattermost:mattermost"],"type":"information_disclosure","year":"2024"},"n_packages":0,"n_references":1,"next":{"headline":"AccessTokenManager has an use after free vulnerability","id":"CVE-2024-39831"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2024-39828"},"products":["Mattermost"],"published":"2024-07-03","related":[{"cvss_score":9.1,"headline":"Path traversal in n/a","id":"CVE-2019-20851","kev_date_added":null,"published":"2020-06-19"},{"cvss_score":8.7,"headline":"Malicious remote can add users to arbitrary teams and channels","id":"CVE-2024-39274","kev_date_added":null,"published":"2024-08-01"},{"cvss_score":8.7,"headline":"Malicious remote can invite itself to an arbitrary local channel","id":"CVE-2024-39777","kev_date_added":null,"published":"2024-08-01"},{"cvss_score":8.1,"headline":"Lack of server certificate validation in websockets connection","id":"CVE-2023-3615","kev_date_added":null,"published":"2023-07-17"},{"cvss_score":7.5,"headline":"Information disclosure in n/a","id":"CVE-2020-13891","kev_date_added":null,"published":"2020-06-26"},{"cvss_score":7.4,"headline":"Existing local user overwritten by malicious remote","id":"CVE-2024-36492","kev_date_added":null,"published":"2024-08-01"}],"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":"2024-08-02","vendors":["Mattermost"]},"summary":"Attackers can retrieve remote cluster tokens via timing attacks when shared channels are enabled, potentially bypassing authentication.","url":"https://insights.sbomify.com/CVE-2024-39830/"}
