Any signed-in user can exploit it over the network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-24356 and fix it if it is affected.\n\nWhat it is: CVE-2021-24356 is a high-severity missing authorization vulnerability in Unknown Simple 301 Redirects by BetterLinks, published on 14 Jun 2021. Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-24356 in the wild and no public exploit code.\n\nAffected product: Unknown Simple 301 Redirects by BetterLinks. 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-2021-24356/ (Markdown: https://insights.sbomify.com/CVE-2021-24356/index.md)","id":"CVE-2021-24356","markdown":"https://insights.sbomify.com/CVE-2021-24356/index.md","name":"CVE-2021-24356","record":{"aliases":["GHSA-x8rw-vx6w-9xw8"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["privilege_escalation","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"low_privilege","summary":"Authenticated users can activate arbitrary plugins due to missing capability checks, potentially leading to privilege escalation or site compromise.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"simple_301_redirects","vendor":"wpdeveloper"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"In the Simple 301 Redirects by BetterLinks WordPress plugin before 2.0.4, a lack of capability checks and insufficient nonce check on the AJAX action, simple301redirects/admin/activate_plugin, made it possible for authenticated users to activate arbitrary plugins installed on vulnerable sites.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2023-08-09","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2023-08-09T18:24:19Z","kind":"github_poc","ref":"https://github.com/RandomRobbieBF/CVE-2021-24356","stars":0,"title":"Simple 301 Redirects by BetterLinks - 2.0.0 – 2.0.3 - Subscriber + Arbitrary Plugin Installation"}],"tier":"poc_unverified"},"has_fix":null,"headline":"Simple 301 Redirects by BetterLinks - 2.0.0 – 2.0.3 - Arbitrary Plugin Activation","id":"CVE-2021-24356","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"FooGallery \u003c 2.0.35 - Authenticated Stored Cross-Site Scripting","id":"CVE-2021-24357"},"packages":[],"prev":{"headline":"Simple 301 Redirects by BetterLinks - 2.0.0 – 2.0.3 - Update and Retrieve Wildcard Value","id":"CVE-2021-24355"},"products":["Simple 301 Redirects by BetterLinks"],"published":"2021-06-14","related":[{"cvss_score":8.8,"headline":"Simple 301 Redirects by BetterLinks - 2.0.0 – 2.0.3 - Unauthenticated Redirect Export","id":"CVE-2021-24352","kev_date_added":null,"published":"2021-06-14"},{"cvss_score":8.8,"headline":"Simple 301 Redirects by BetterLinks - 2.0.0 – 2.0.3 - Unauthenticated Redirect Import","id":"CVE-2021-24353","kev_date_added":null,"published":"2021-06-14"},{"cvss_score":8.8,"headline":"Simple 301 Redirects by BetterLinks - 2.0.0-2.0.3 - Arbitrary Plugin Installation","id":"CVE-2021-24354","kev_date_added":null,"published":"2021-06-14"},{"cvss_score":4.3,"headline":"Simple 301 Redirects by BetterLinks - 2.0.0 – 2.0.3 - Update and Retrieve Wildcard Value","id":"CVE-2021-24355","kev_date_added":null,"published":"2021-06-14"}],"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["Unknown"]},"summary":"Authenticated users can activate arbitrary plugins due to missing capability checks, potentially leading to privilege escalation or site compromise.","url":"https://insights.sbomify.com/CVE-2021-24356/"}
