Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-5751 in the wild and no public exploit code.\n\nAffected product: TCExam. 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-2020-5751/ (Markdown: https://insights.sbomify.com/CVE-2020-5751/index.md)","id":"CVE-2020-5751","markdown":"https://insights.sbomify.com/CVE-2020-5751/index.md","name":"CVE-2020-5751","record":{"aliases":["GHSA-q83w-2c4p-x7mv"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"TCExam web application","requires_auth":"low_privilege","summary":"Remote authenticated attackers can execute persistent cross-site scripting attacks in TCExam by creating a crafted operator, potentially leading to session hijacking or malicious code execution.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"tenable","cpe":[{"product":"tcexam","vendor":"tecnick"}],"cvss":{"score":5.4,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/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":"Insufficient output sanitization in TCExam 14.2.2 allows a remote, authenticated attacker to conduct persistent cross-site scripting (XSS) attacks by creating a crafted operator.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Cross-site scripting in TCExam","id":"CVE-2020-5751","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Path traversal in Druva inSync Windows Client","id":"CVE-2020-5752"},"packages":[],"prev":{"headline":"Cross-site scripting in TCExam","id":"CVE-2020-5750"},"products":["TCExam"],"published":"2020-05-07","related":[{"cvss_score":7.5,"headline":"Information disclosure in TCExam","id":"CVE-2021-20114","kev_date_added":null,"published":"2021-07-29"},{"cvss_score":7.4,"headline":"Cross-site request forgery in TCExam","id":"CVE-2020-5745","kev_date_added":null,"published":"2020-05-07"},{"cvss_score":6.8,"headline":"SQL injection in n/a","id":"CVE-2012-4237","kev_date_added":null,"published":"2012-08-20"},{"cvss_score":6.8,"headline":"File upload in n/a","id":"CVE-2010-2153","kev_date_added":null,"published":"2010-06-03"},{"cvss_score":6.5,"headline":"Missing authorisation in TCExam","id":"CVE-2023-6554","kev_date_added":null,"published":"2024-01-11"},{"cvss_score":6.1,"headline":"Cross-site scripting in TCExam","id":"CVE-2021-20115","kev_date_added":null,"published":"2021-08-05"},{"cvss_score":6.1,"headline":"Cross-site scripting in TCExam","id":"CVE-2021-20116","kev_date_added":null,"published":"2021-08-05"}],"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":"Remote authenticated attackers can execute persistent cross-site scripting attacks in TCExam by creating a crafted operator, potentially leading to session hijacking or malicious code execution.","url":"https://insights.sbomify.com/CVE-2020-5751/"}
