Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-11091 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-2018-11091/ (Markdown: https://insights.sbomify.com/CVE-2018-11091/index.md)","id":"CVE-2018-11091","markdown":"https://insights.sbomify.com/CVE-2018-11091/index.md","name":"CVE-2018-11091","record":{"aliases":["GHSA-ph56-52p3-8fjx"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"MyBiz MyProcureNet","requires_auth":"low_privilege","summary":"Attackers can upload malicious scripts by manipulating extension whitelists, leading to arbitrary command execution and server takeover.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"myprocurenet","vendor":"mybiz"}],"cvss":{"score":9.9,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-434","name":"Unrestricted Upload of File with Dangerous Type"}],"description":"An issue was discovered in MyBiz MyProcureNet 5.0.0. A malicious file can be uploaded to the webserver by an attacker. It is possible for an attacker to upload a script to issue operating system commands. This vulnerability occurs because an attacker is able to adjust the \"HiddenFieldControlCustomWhiteListedExtensions\" parameter and add arbitrary extensions to the whitelist during the upload. For instance, if the extension .asp is added to the \"HiddenFieldControlCustomWhiteListedExtensions\" parameter, the server accepts \"secctest.asp\" as a legitimate file. Hence malicious files can be uploaded in order to execute arbitrary commands to take over the server.","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":"File upload in n/a","id":"CVE-2018-11091","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"file_upload","year":"2018"},"n_packages":0,"n_references":5,"next":{"headline":"Cross-site request forgery in n/a","id":"CVE-2018-11092"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2018-11090"},"products":["n/a"],"published":"2018-05-14","related":[{"cvss_score":6.1,"headline":"Cross-site scripting in n/a","id":"CVE-2018-11090","kev_date_added":null,"published":"2018-05-14"}],"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":"2026-05-29","vendors":["n/a"]},"summary":"Attackers can upload malicious scripts by manipulating extension whitelists, leading to arbitrary command execution and server takeover.","url":"https://insights.sbomify.com/CVE-2018-11091/"}
