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-2018-11773 in the wild and no public exploit code.\n\nAffected product: Apache VCL. 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-2018-11773/ (Markdown: https://insights.sbomify.com/CVE-2018-11773/index.md)","id":"CVE-2018-11773","markdown":"https://insights.sbomify.com/CVE-2018-11773/index.md","name":"CVE-2018-11773","record":{"aliases":["GHSA-wmc6-cwxh-j3rp"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["other"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache VCL","requires_auth":"none","summary":"Improper input validation in Apache VCL allows potential attacks on the underlying strtotime function, though exploitation was deemed resistant at discovery.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"virtual_computing_lab","vendor":"apache"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Apache VCL versions 2.1 through 2.5 do not properly validate form input when processing a submitted block allocation. The form data is then used as an argument to the php built in function strtotime. This allows for an attack against the underlying implementation of that function. The implementation of strtotime at the time the issue was discovered appeared to be resistant to a malicious attack. However, all VCL systems running versions earlier than 2.5.1 should be upgraded or patched. This vulnerability was found and reported to the Apache VCL project by ADLab of Venustech.","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":"Other in VCL","id":"CVE-2018-11773","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2018"},"n_packages":0,"n_references":2,"next":{"headline":"SQL injection in VCL","id":"CVE-2018-11774"},"packages":[],"prev":{"headline":"SQL injection in VCL","id":"CVE-2018-11772"},"products":["VCL"],"published":"2019-07-29","related":[{"cvss_score":7.2,"headline":"SQL injection in VCL","id":"CVE-2018-11772","kev_date_added":null,"published":"2019-07-29"},{"cvss_score":7.2,"headline":"SQL injection in VCL","id":"CVE-2018-11774","kev_date_added":null,"published":"2019-07-29"}],"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":"2024-08-05","vendors":["Apache"]},"summary":"Improper input validation in Apache VCL allows potential attacks on the underlying strtotime function, though exploitation was deemed resistant at discovery.","url":"https://insights.sbomify.com/CVE-2018-11773/"}
