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-2021-32795 in the wild and no public exploit code.\n\nAffected product: JustArchiNET ArchiSteamFarm. 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-2021-32795/ (Markdown: https://insights.sbomify.com/CVE-2021-32795/index.md)","id":"CVE-2021-32795","markdown":"https://insights.sbomify.com/CVE-2021-32795/index.md","name":"CVE-2021-32795","record":{"aliases":["GHSA-5v34-4prm-9474"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Steam bot application","requires_auth":"none","summary":"An unauthenticated attacker can crash the ArchiSteamFarm application by sending a crafted Steam chat message, causing a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"archisteamfarm","vendor":"archisteamfarm_project"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"ArchiSteamFarm is a C# application with primary purpose of idling Steam cards from multiple accounts simultaneously. In versions prior to 4.3.1.0 a Denial of Service (aka DoS) vulnerability which allows attacker to remotely crash running ASF instance through sending a specifically-crafted Steam chat message exists. The user sending the message does not need to be authorized within the bot or ASF process. The attacker needs to know ASF's `CommandPrefix` in advance, but majority of ASF setups run with an unchanged default value. This attack does not allow attacker to gain any potentially-sensitive information, such as logins or passwords, does not allow to execute arbitrary commands and otherwise exploit the crash further. The issue is patched in ASF V4.3.1.0. The only workaround which guarantees complete protection is running all bots with `OnlineStatus` of `0` (Offline). In this setup, ASF is able to ignore even the specifically-crafted message without attempting to interpret it.","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":"Denial of Service via Steam chat in ArchiSteamFarm","id":"CVE-2021-32795","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2021"},"n_packages":0,"n_references":3,"next":{"headline":"Misinterpretation of malicious XML input in xmldom","id":"CVE-2021-32796"},"packages":[],"prev":{"headline":"Accidental removal of IPCPassword (\u003c 5.1.2.4)","id":"CVE-2021-32794"},"products":["ArchiSteamFarm"],"published":"2021-07-26","related":[{"cvss_score":6.8,"headline":"Accidental removal of IPCPassword (\u003c 5.1.2.4)","id":"CVE-2021-32794","kev_date_added":null,"published":"2021-07-26"},{"cvss_score":5,"headline":"Inadequate access verification when using proxy commands in ArchiSteamFarm","id":"CVE-2022-23627","kev_date_added":null,"published":"2022-02-08"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["JustArchiNET"]},"summary":"An unauthenticated attacker can crash the ArchiSteamFarm application by sending a crafted Steam chat message, causing a denial of service.","url":"https://insights.sbomify.com/CVE-2021-32795/"}
