An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2020-5775 exists.\n\nAffected packages and fixed versions:\n- canvaslms (Bitnami): affected from 2020-07-29.0.0 up to 2020-07-29.0.0; no fix listed\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-2020-5775/ (Markdown: https://insights.sbomify.com/CVE-2020-5775/index.md)","id":"CVE-2020-5775","markdown":"https://insights.sbomify.com/CVE-2020-5775/index.md","name":"CVE-2020-5775","record":{"aliases":["BIT-canvaslms-2020-5775","GHSA-wp9p-6x4v-9fxx"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Canvas LMS","requires_auth":"none","summary":"Remote unauthenticated attackers can force Canvas LMS to make arbitrary HTTP GET requests, potentially accessing internal resources or bypassing network restrictions.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"tenable","cpe":[{"product":"canvas_learning_management_service","vendor":"instructure"}],"cvss":{"score":5.8,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"}],"description":"Server-Side Request Forgery in Canvas LMS 2020-07-29 allows a remote, unauthenticated attacker to cause the Canvas application to perform HTTP GET requests to arbitrary domains.","ecosystems":["Bitnami"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":1,"refs":[{"date":null,"kind":"nuclei","ref":"http/cves/2020/CVE-2020-5775.yaml","stars":null,"title":"Canvas LMS v2020-07-29 - Blind Server-Side Request Forgery"}],"tier":"weaponised"},"has_fix":false,"headline":"Server-side request forgery in Instructure Canvas Learning Management System (LMS)","id":"CVE-2020-5775","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"ssrf","year":"2020"},"n_packages":1,"n_references":1,"next":{"headline":"Cross-Site Request Forgery in MAGMI","id":"CVE-2020-5776"},"packages":[{"ecosystem":"Bitnami","fixed":[],"introduced":["2020-07-29.0.0"],"last_affected":["2020-07-29.0.0"],"package":"canvaslms","purl":"pkg:bitnami/canvaslms","source":"BIT-canvaslms-2020-5775"}],"prev":{"headline":"Auth bypass in Tenable Nessus","id":"CVE-2020-5774"},"products":["Instructure Canvas Learning Management System (LMS)"],"published":"2020-08-21","related":[{"cvss_score":6.5,"headline":"Missing authorization in n/a","id":"CVE-2021-36539","kev_date_added":null,"published":"2023-01-26"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"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":"attribution","licence":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Remote unauthenticated attackers can force Canvas LMS to make arbitrary HTTP GET requests, potentially accessing internal resources or bypassing network restrictions.","url":"https://insights.sbomify.com/CVE-2020-5775/"}
