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-2020-23591 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2020-23591/ (Markdown: https://insights.sbomify.com/CVE-2020-23591/index.md)","id":"CVE-2020-23591","markdown":"https://insights.sbomify.com/CVE-2020-23591/index.md","name":"CVE-2020-23591","record":{"aliases":["GHSA-4m25-prjm-246w"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"OPTILINK router","requires_auth":"none","summary":"An attacker can upload arbitrary files to the OPTILINK router to execute code, create backdoors, or cause denial of service.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"op-xt71000n_firmware","vendor":"optilinknetwork"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-434","name":"Unrestricted Upload of File with Dangerous Type"}],"description":"A vulnerability in OPTILINK OP-XT71000N Hardware Version: V2.2 , Firmware Version: OP_V3.3.1-191028 allows an attacker to upload arbitrary files through \" /mgm_dev_upgrade.asp \" which can \"delete every file for Denial of Service (using 'rm -rf *.*' in the code), reverse connection (using '.asp' webshell), backdoor.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2022-11-20","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2022-11-20T17:38:06Z","kind":"github_poc","ref":"https://github.com/huzaifahussain98/CVE-2020-23591","stars":0,"title":"ARBITAR FILE UPLOAD LEADS TO \"delete every file for Denial of Service (using 'rm -rf *.*' in the code), reverse connection (using '.asp' webshell), backdoor , Escalation of Privileges, etc\"."}],"tier":"poc_unverified"},"has_fix":null,"headline":"File upload in n/a","id":"CVE-2020-23591","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"file_upload","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Cross-site request forgery in n/a","id":"CVE-2020-23592"},"packages":[],"prev":{"headline":"Cross-site request forgery in n/a","id":"CVE-2020-23590"},"products":["n/a"],"published":"2022-11-23","related":[{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2020-23583","kev_date_added":null,"published":"2022-11-23"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2020-23584","kev_date_added":null,"published":"2022-11-23"},{"cvss_score":8.8,"headline":"Cross-site request forgery in n/a","id":"CVE-2020-23585","kev_date_added":null,"published":"2022-11-23"},{"cvss_score":8.8,"headline":"Cross-site request forgery in n/a","id":"CVE-2020-23592","kev_date_added":null,"published":"2022-11-23"},{"cvss_score":6.5,"headline":"Cross-site request forgery in n/a","id":"CVE-2020-23589","kev_date_added":null,"published":"2022-11-23"},{"cvss_score":6.5,"headline":"Cross-site request forgery in n/a","id":"CVE-2020-23590","kev_date_added":null,"published":"2022-11-23"}],"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-04-29","vendors":["n/a"]},"summary":"An attacker can upload arbitrary files to the OPTILINK router to execute code, create backdoors, or cause denial of service.","url":"https://insights.sbomify.com/CVE-2020-23591/"}
