An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2020-20523 exists.\n\nAffected packages and fixed versions:\n- gilacms/gila (Packagist): affected all versions; fixed in 1.11.4\n- gilacms/gila (Packagist): affected all versions; fixed in 1.11.4\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-2020-20523/ (Markdown: https://insights.sbomify.com/CVE-2020-20523/index.md)","id":"CVE-2020-20523","markdown":"https://insights.sbomify.com/CVE-2020-20523/index.md","name":"CVE-2020-20523","record":{"aliases":["GHSA-rvjp-j5j4-c9j5"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Gila CMS","requires_auth":"none","summary":"Remote attackers can execute arbitrary code via XSS in the adm_user parameter during Gila CMS installation.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"gila_cms","vendor":"gilacms"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Cross Site Scripting (XSS) vulnerability in adm_user parameter in Gila CMS version 1.11.3, allows remote attackers to execute arbitrary code during the Gila CMS installation.","ecosystems":["Packagist"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Gila CMS Cross-site Scripting Vulnerability","id":"CVE-2020-20523","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"xss","year":"2020"},"n_packages":2,"n_references":1,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2020-20545"},"packages":[{"ecosystem":"Packagist","fixed":["1.11.4"],"introduced":["0"],"last_affected":[],"package":"gilacms/gila","purl":null,"source":"GHSA-rvjp-j5j4-c9j5"},{"ecosystem":"Packagist","fixed":["1.11.4"],"introduced":["0"],"last_affected":[],"package":"gilacms/gila","purl":"pkg:composer/gilacms/gila","source":"GHSA-rvjp-j5j4-c9j5"}],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2020-20522"},"products":["n/a"],"published":"2023-08-11","related":[{"cvss_score":9.9,"headline":"File upload in n/a","id":"CVE-2019-17536","kev_date_added":null,"published":"2019-10-13"},{"cvss_score":9.3,"headline":"Cross-site scripting in n/a","id":"CVE-2019-17535","kev_date_added":null,"published":"2019-10-13"},{"cvss_score":9.1,"headline":"File upload in n/a","id":"CVE-2020-5514","kev_date_added":null,"published":"2020-01-06"},{"cvss_score":8.8,"headline":"GilaCMS Cross Site Request Forgery vulnerability","id":"CVE-2020-20726","kev_date_added":null,"published":"2023-06-20"},{"cvss_score":8.8,"headline":"Cross-Site Request Forgery in GilaCMS","id":"CVE-2020-20693","kev_date_added":null,"published":"2021-09-27"},{"cvss_score":8.8,"headline":"Cross-site request forgery in n/a","id":"CVE-2019-20804","kev_date_added":null,"published":"2020-05-21"},{"cvss_score":8.8,"headline":"Cross-site request forgery in n/a","id":"CVE-2019-11456","kev_date_added":null,"published":"2019-04-22"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-10-09","vendors":["n/a"]},"summary":"Remote attackers can execute arbitrary code via XSS in the adm_user parameter during Gila CMS installation.","url":"https://insights.sbomify.com/CVE-2020-20523/"}
