An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2018-16303 and fix it if it is affected.\n\nWhat it is: CVE-2018-16303 is a high-severity vulnerability in Pdf-Xchange Pdf-Xchange Editor, published on 1 Sep 2018. An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-16303 in the wild and no public exploit code.\n\nAffected product: Pdf-Xchange Pdf-Xchange Editor. 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-2018-16303/ (Markdown: https://insights.sbomify.com/CVE-2018-16303/index.md)","id":"CVE-2018-16303","markdown":"https://insights.sbomify.com/CVE-2018-16303/index.md","name":"CVE-2018-16303","record":{"aliases":["GHSA-55ph-9w63-r34w"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"PDF editor","requires_auth":"none","summary":"Remote attackers can cause denial of service in PDF-XChange Editor via crafted XML metadata, requiring users to update the software.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"pdf-xchange_editor","vendor":"pdf-xchange"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-611","name":"Improper Restriction of XML External Entity Reference"}],"description":"PDF-XChange Editor through 7.0.326.1 allows remote attackers to cause a denial of service (resource consumption) via a crafted x:xmpmeta structure, a related issue to CVE-2003-1564.","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":"XML external entity in n/a","id":"CVE-2018-16303","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"pdf-xchange:pdf-xchange_editor","products":["pdf-xchange:pdf-xchange_editor"],"type":"xxe","year":"2018"},"n_packages":0,"n_references":1,"next":{"headline":"Server-side request forgery in n/a","id":"CVE-2018-16307"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2018-16302"},"products":["n/a"],"published":"2018-09-01","related":[{"cvss_score":7.8,"headline":"PDF-XChange Editor AcroForm Use-After-Free Remote Code Execution Vulnerability","id":"CVE-2025-0899","kev_date_added":null,"published":"2025-02-11"},{"cvss_score":7.8,"headline":"PDF-XChange Editor Doc Object Out-Of-Bounds Read Remote Code Execution Vulnerability","id":"CVE-2025-0901","kev_date_added":null,"published":"2025-02-11"},{"cvss_score":7.8,"headline":"PDF-XChange Editor RTF File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability","id":"CVE-2025-0903","kev_date_added":null,"published":"2025-02-11"},{"cvss_score":7.8,"headline":"PDF-XChange Editor U3D File Parsing Out-Of-Bounds Write Remote Code Execution Vulnerability","id":"CVE-2025-0910","kev_date_added":null,"published":"2025-02-11"},{"cvss_score":7.8,"headline":"PDF-XChange Editor PDF File Parsing Out-Of-Bounds Write Remote Code Execution Vulnerability","id":"CVE-2024-7352","kev_date_added":null,"published":"2024-11-22"},{"cvss_score":7.8,"headline":"This vulnerability allows remote attackers to execute arbitrary code on affected installations of PDF-XChange Editor.","id":"CVE-2022-37349","kev_date_added":null,"published":"2023-03-29"},{"cvss_score":7.8,"headline":"Memory corruption in PDF-XChange Editor","id":"CVE-2022-37350","kev_date_added":null,"published":"2023-03-29"}],"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":"2024-08-05","vendors":["n/a"]},"summary":"Remote attackers can cause denial of service in PDF-XChange Editor via crafted XML metadata, requiring users to update the software.","url":"https://insights.sbomify.com/CVE-2018-16303/"}
