An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2020-27652 and fix it if it is affected.\n\nWhat it is: CVE-2020-27652 is a high-severity vulnerability in Synology Diskstation Manager, published on 29 Oct 2020. 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-2020-27652 in the wild and no public exploit code.\n\nAffected product: Synology Diskstation Manager. 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-2020-27652/ (Markdown: https://insights.sbomify.com/CVE-2020-27652/index.md)","id":"CVE-2020-27652","markdown":"https://insights.sbomify.com/CVE-2020-27652/index.md","name":"CVE-2020-27652","record":{"aliases":["GHSA-c4cp-hjxc-9m9g"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"NAS management software","requires_auth":"none","summary":"Man-in-the-middle attackers can downgrade encryption algorithms in Synology DSM QuickConnect to spoof servers and obtain sensitive information.","user_interaction":"required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"synology","cpe":[{"product":"diskstation_manager","vendor":"synology"},{"product":"skynas_firmware","vendor":"synology"}],"cvss":{"score":8.3,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-327","name":"Use of a Broken or Risky Cryptographic Algorithm"}],"description":"Algorithm downgrade vulnerability in QuickConnect in Synology DiskStation Manager (DSM) before 6.2.3-25426-2 allows man-in-the-middle attackers to spoof servers and obtain sensitive information via unspecified vectors.","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":"Weak cryptography in DiskStation Manager (DSM)","id":"CVE-2020-27652","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"synology:diskstation_manager","products":["synology:diskstation_manager"],"type":"weak_cryptography","year":"2020"},"n_packages":0,"n_references":2,"next":{"headline":"Weak cryptography in Synology Router Manager (SRM)","id":"CVE-2020-27653"},"packages":[],"prev":{"headline":"Information disclosure in Synology Router Manager (SRM)","id":"CVE-2020-27651"},"products":["DiskStation Manager (DSM)"],"published":"2020-10-29","related":[{"cvss_score":10,"headline":"Memory corruption in DiskStation Manager (DSM)","id":"CVE-2022-27624","kev_date_added":null,"published":"2022-10-20"},{"cvss_score":10,"headline":"Memory corruption in DiskStation Manager (DSM)","id":"CVE-2022-27625","kev_date_added":null,"published":"2022-10-20"},{"cvss_score":10,"headline":"Race condition in DiskStation Manager (DSM)","id":"CVE-2022-27626","kev_date_added":null,"published":"2022-10-20"},{"cvss_score":10,"headline":"Path traversal in n/a","id":"CVE-2013-6955","kev_date_added":null,"published":"2014-01-09"},{"cvss_score":9.8,"headline":"Memory corruption in DiskStation Manager (DSM)","id":"CVE-2022-22687","kev_date_added":null,"published":"2022-03-25"},{"cvss_score":9.8,"headline":"Use after free in DiskStation Manager (DSM)","id":"CVE-2021-27649","kev_date_added":null,"published":"2021-06-23"},{"cvss_score":9.8,"headline":"Race condition in Synology DiskStation Manager (DSM)","id":"CVE-2021-26569","kev_date_added":null,"published":"2021-03-12"}],"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":"2024-09-16","vendors":["Synology"]},"summary":"Man-in-the-middle attackers can downgrade encryption algorithms in Synology DSM QuickConnect to spoof servers and obtain sensitive information.","url":"https://insights.sbomify.com/CVE-2020-27652/"}
