Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-42940 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-2021-42940/ (Markdown: https://insights.sbomify.com/CVE-2021-42940/index.md)","id":"CVE-2021-42940","markdown":"https://insights.sbomify.com/CVE-2021-42940/index.md","name":"CVE-2021-42940","record":{"aliases":["GHSA-qjr7-64vh-gjxw"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Projeqtor project management","requires_auth":"low_privilege","summary":"An attacker can execute arbitrary JavaScript in the victim's browser by uploading a malicious SVG file to the attachment handler.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"projeqtor","vendor":"projeqtor"}],"cvss":{"score":9.9,"severity":"critical","source":"nvd","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-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"A Cross Site Scripting (XSS) vulnerability exists in Projeqtor 9.3.1 via /projeqtor/tool/saveAttachment.php, which allows an attacker to upload a SVG file containing malicious JavaScript code.","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":"Cross-site scripting in n/a","id":"CVE-2021-42940","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2021-42943"},"packages":[],"prev":{"headline":"Code injection in n/a","id":"CVE-2021-42923"},"products":["n/a"],"published":"2022-02-11","related":[{"cvss_score":8.8,"headline":"File upload in n/a","id":"CVE-2024-29387","kev_date_added":null,"published":"2024-04-04"},{"cvss_score":8.8,"headline":"File upload in n/a","id":"CVE-2018-18924","kev_date_added":null,"published":"2018-11-04"},{"cvss_score":8.8,"headline":"File upload in n/a","id":"CVE-2017-11760","kev_date_added":null,"published":"2017-07-31"},{"cvss_score":7.5,"headline":"SQL injection in n/a","id":"CVE-2013-6164","kev_date_added":null,"published":"2013-11-14"},{"cvss_score":6.1,"headline":"Cross-site scripting in n/a","id":"CVE-2023-49034","kev_date_added":null,"published":"2024-02-20"},{"cvss_score":5.4,"headline":"SQL injection in n/a","id":"CVE-2024-29386","kev_date_added":null,"published":"2024-04-04"}],"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":"2024-08-04","vendors":["n/a"]},"summary":"An attacker can execute arbitrary JavaScript in the victim's browser by uploading a malicious SVG file to the attachment handler.","url":"https://insights.sbomify.com/CVE-2021-42940/"}
