An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-13579 in the wild and no public exploit code.\n\nAffected product: Softmaker Software. 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-2020-13579/ (Markdown: https://insights.sbomify.com/CVE-2020-13579/index.md)","id":"CVE-2020-13579","markdown":"https://insights.sbomify.com/CVE-2020-13579/index.md","name":"CVE-2020-13579","record":{"aliases":["GHSA-9rhj-8q3f-7x84"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Office suite","requires_auth":"none","summary":"An attacker can execute arbitrary code by tricking a user into opening a specially crafted document in SoftMaker Office PlanMaker.","user_interaction":"required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"talos","cpe":[{"product":"planmaker_2021","vendor":"softmaker"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"An exploitable integer overflow vulnerability exists in the PlanMaker document parsing functionality of SoftMaker Office 2021’s PlanMaker application. A specially crafted document can cause the document parser perform arithmetic that may overflow which can result in an undersized heap allocation. Later when copying data from the file into this allocation, a heap-based buffer overflow will occur which can corrupt memory. These types of memory corruptions can allow for code execution under the context of the application. An attacker can entice the victim to open a document to trigger this vulnerability.","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":"Integer overflow in Softmaker Software","id":"CVE-2020-13579","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"integer_overflow","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in Softmaker Software","id":"CVE-2020-13580"},"packages":[],"prev":{"headline":"Null dereference in Genivia","id":"CVE-2020-13578"},"products":["Softmaker Software"],"published":"2021-02-04","related":[{"cvss_score":8.8,"headline":"Memory corruption in Softmaker","id":"CVE-2020-28587","kev_date_added":null,"published":"2021-02-23"},{"cvss_score":8.8,"headline":"Memory corruption in SoftMaker","id":"CVE-2020-13581","kev_date_added":null,"published":"2021-02-10"},{"cvss_score":8.8,"headline":"Memory corruption in SoftMaker","id":"CVE-2020-27250","kev_date_added":null,"published":"2021-02-10"},{"cvss_score":8.8,"headline":"Memory corruption in Softmaker Software","id":"CVE-2020-13580","kev_date_added":null,"published":"2021-02-04"},{"cvss_score":8.8,"headline":"Memory corruption in Softmaker","id":"CVE-2020-13586","kev_date_added":null,"published":"2021-02-04"},{"cvss_score":8.8,"headline":"Memory corruption in Softmaker","id":"CVE-2020-27247","kev_date_added":null,"published":"2021-02-04"}],"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 code by tricking a user into opening a specially crafted document in SoftMaker Office PlanMaker.","url":"https://insights.sbomify.com/CVE-2020-13579/"}
