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-2021-20108 in the wild and no public exploit code.\n\nAffected product: Manage Engine Asset Explorer Agent. 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-2021-20108/ (Markdown: https://insights.sbomify.com/CVE-2021-20108/index.md)","id":"CVE-2021-20108","markdown":"https://insights.sbomify.com/CVE-2021-20108/index.md","name":"CVE-2021-20108","record":{"aliases":["GHSA-x7m4-fg9v-r3j5"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Asset Explorer Agent","requires_auth":"none","summary":"Remote attackers can crash the Manage Engine Asset Explorer Agent by sending repeated commands that trigger memory leaks due to missing certificate validation and improper memory management.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"tenable","cpe":[{"product":"manageengine_assetexplorer","vendor":"zohocorp"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-401","name":"Missing Release of Memory after Effective Lifetime"}],"description":"Manage Engine Asset Explorer Agent 1.0.34 listens on port 9000 for incoming commands over HTTPS from Manage Engine Server. The HTTPS certificates are not verified which allows any arbitrary user on the network to send commands over port 9000. While these commands may not be executed (due to authtoken validation), the Asset Explorer agent will reach out to the manage engine server for an HTTP request. During this process, AEAgent.cpp allocates 0x66 bytes using \"malloc\". This memory is never free-ed in the program, causing a memory leak. Additionally, the instruction sent to aeagent (ie: NEWSCAN, DELTASCAN, etc) is converted to a unicode string, but is never freed. These memory leaks allow a remote attacker to exploit a Denial of Service scenario through repetitively sending these commands to an agent and eventually crashing it the agent due to an out-of-memory condition.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Denial of service in Manage Engine Asset Explorer Agent","id":"CVE-2021-20108","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in Manage Engine Asset Explorer Agent","id":"CVE-2021-20109"},"packages":[],"prev":{"headline":"Missing authorization in SLOAN","id":"CVE-2021-20107"},"products":["Manage Engine Asset Explorer Agent"],"published":"2021-07-19","related":[{"cvss_score":9.8,"headline":"Integer overflow in Manage Engine Asset Explorer Agent","id":"CVE-2021-20110","kev_date_added":null,"published":"2021-07-19"},{"cvss_score":9.1,"headline":"Server-side request forgery in n/a","id":"CVE-2019-12994","kev_date_added":null,"published":"2019-08-08"},{"cvss_score":8.8,"headline":"Server-side request forgery in n/a","id":"CVE-2019-12959","kev_date_added":null,"published":"2019-08-08"},{"cvss_score":8.5,"headline":"XML external entity in n/a","id":"CVE-2019-14693","kev_date_added":null,"published":"2019-08-08"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2023-26601","kev_date_added":null,"published":"2023-03-06"},{"cvss_score":7.5,"headline":"Information disclosure in n/a","id":"CVE-2022-35403","kev_date_added":null,"published":"2022-07-12"}],"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":["n/a"]},"summary":"Remote attackers can crash the Manage Engine Asset Explorer Agent by sending repeated commands that trigger memory leaks due to missing certificate validation and improper memory management.","url":"https://insights.sbomify.com/CVE-2021-20108/"}
