It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2023-34634 and fix it if it is affected.\n\nWhat it is: CVE-2023-34634 is a high-severity unsafe deserialization vulnerability in n/a, published on 1 Aug 2023. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-34634 exists.\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-2023-34634/ (Markdown: https://insights.sbomify.com/CVE-2023-34634/index.md)","id":"CVE-2023-34634","markdown":"https://insights.sbomify.com/CVE-2023-34634/index.md","name":"CVE-2023-34634","record":{"aliases":["GHSA-8743-hwvq-mj5j"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Screenshot tool","requires_auth":"none","summary":"An attacker can execute arbitrary code by tricking a user into opening a malicious .greenshot file in Greenshot.","user_interaction":"required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"greenshot","vendor":"getgreenshot"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"Greenshot 1.2.10 and below allows arbitrary code execution because .NET content is insecurely deserialized when a .greenshot file is opened.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2023-07-26","github_poc":1,"max_poc_stars":2,"metasploit":1,"nuclei":0,"refs":[{"date":"2023-08-18T09:00:44Z","kind":"github_poc","ref":"https://github.com/radman404/CVE-2023-34634","stars":2,"title":"Python rewrite of the POC for CVE-2023-34634"},{"date":"2023-07-26","kind":"metasploit","ref":"exploit/windows/fileformat/greenshot_deserialize_cve_2023_34634","stars":null,"title":"Greenshot .NET Deserialization Fileformat Exploit"},{"date":"2023-07-28","kind":"exploitdb","ref":"51633","stars":null,"title":"GreenShot  1.2.10 - Insecure Deserialization Arbitrary Code Execution"}],"tier":"weaponised"},"has_fix":false,"headline":"Deserialization in n/a","id":"CVE-2023-34634","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"deserialization","year":"2023"},"n_packages":0,"n_references":5,"next":{"headline":"SQL injection in n/a","id":"CVE-2023-34635"},"packages":[],"prev":{"headline":"SQL injection in n/a","id":"CVE-2023-34626"},"products":["n/a"],"published":"2023-08-01","related":[{"cvss_score":8.4,"headline":"Greenshot — Insecure .NET deserialization via WM_COPYDATA enables local code execution","id":"CVE-2025-59050","kev_date_added":null,"published":"2025-09-16"},{"cvss_score":7.8,"headline":"Greenshot Vulnerable to OS Command Injection via ExternalCommand Plugin","id":"CVE-2026-22035","kev_date_added":null,"published":"2026-01-08"},{"cvss_score":6.5,"headline":"Greenshot Vulnerable to OS Command Injection via ExternalCommand Plugin","id":"CVE-2026-25792","kev_date_added":null,"published":"2026-03-20"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"attribution","licence":"BSD-3-Clause","name":"Metasploit"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-10-23","vendors":["n/a"]},"summary":"An attacker can execute arbitrary code by tricking a user into opening a malicious .greenshot file in Greenshot.","url":"https://insights.sbomify.com/CVE-2023-34634/"}
