An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: Yes. Attackers have exploited CVE-2023-37580 in the wild since at least 27 Jul 2023.\n\nAffected product: Synacor Zimbra Collaboration Suite. 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-2023-37580/ (Markdown: https://insights.sbomify.com/CVE-2023-37580/index.md)","id":"CVE-2023-37580","markdown":"https://insights.sbomify.com/CVE-2023-37580/index.md","name":"CVE-2023-37580","record":{"aliases":["GHSA-vw6f-667c-3jv3"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Zimbra Collaboration","requires_auth":"none","summary":"Cross-site scripting in Zimbra Classic Web Client allows attackers to execute scripts or hijack sessions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"zimbra_collaboration_suite","vendor":"synacor"}],"cvss":{"score":6.1,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/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":"Zimbra Collaboration (ZCS) 8 before 8.8.15 Patch 41 allows XSS in the Zimbra Classic Web Client.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":1,"refs":[{"date":null,"kind":"nuclei","ref":"http/cves/2023/CVE-2023-37580.yaml","stars":null,"title":"Zimbra Collaboration Suite (ZCS) v.8.8.15 - Cross-Site Scripting"}],"tier":"exploited"},"has_fix":false,"headline":"Synacor Zimbra Collaboration Suite (ZCS) Cross-Site Scripting (XSS)","id":"CVE-2023-37580","indexable":true,"kev":{"dateAdded":"2023-07-27","dueDate":"2023-08-17","knownRansomwareCampaignUse":"Unknown","product":"Zimbra Collaboration Suite (ZCS)","requiredAction":"Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.","vendorProject":"Synacor","vulnerabilityName":"Synacor Zimbra Collaboration Suite (ZCS) Cross-Site Scripting (XSS) Vulnerability"},"kind":"cve","links":{"ecosystem":null,"product":"synacor:zimbra_collaboration_suite","products":["synacor:zimbra_collaboration_suite"],"type":"xss","year":"2023"},"n_packages":0,"n_references":3,"next":{"headline":"Cross-site scripting in Apache Roller","id":"CVE-2023-37581"},"packages":[],"prev":{"headline":"Apache Pulsar Function Worker: Incorrect Authorization for Function Worker Can Leak Sink/Source Credentials","id":"CVE-2023-37579"},"products":["n/a"],"published":"2023-07-31","related":[{"cvss_score":10,"headline":"Synacor Zimbra Collaboration Suite (ZCS) Command Execution","id":"CVE-2024-45519","kev_date_added":"2024-10-03","published":"2024-10-02"},{"cvss_score":9.8,"headline":"Synacor Zimbra Collaboration Suite (ZCS) Arbitrary File Upload","id":"CVE-2022-41352","kev_date_added":"2022-10-20","published":"2022-09-26"},{"cvss_score":9.8,"headline":"Synacor Zimbra Collaboration Suite (ZCS) Authentication Bypass","id":"CVE-2022-37042","kev_date_added":"2022-08-11","published":"2022-08-11"},{"cvss_score":9.8,"headline":"Synacor Zimbra Collaboration Suite (ZCS) Command Injection","id":"CVE-2022-27924","kev_date_added":"2022-08-04","published":"2022-04-20"},{"cvss_score":9.8,"headline":"Synacor Zimbra Collaboration Suite (ZCS) Server-Side Request Forgery","id":"CVE-2020-7796","kev_date_added":"2026-02-17","published":"2020-02-18"},{"cvss_score":9.8,"headline":"Synacor Zimbra Collaboration Suite (ZCS) Improper Restriction of XML External Entity Reference","id":"CVE-2019-9670","kev_date_added":"2022-01-10","published":"2019-05-29"},{"cvss_score":9,"headline":"Synacor Zimbra Collaboration Suite (ZCS) Cross-Site Scripting (XSS)","id":"CVE-2023-34192","kev_date_added":"2025-02-25","published":"2023-07-06"}],"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":"open","licence":"CC0 1.0","name":"CISA KEV"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"attribution","licence":"MIT","name":"Nuclei templates"}],"ssvc":{"automatable":"no","exploitation":"active","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-10-30","vendors":["n/a"]},"summary":"Cross-site scripting in Zimbra Classic Web Client allows attackers to execute scripts or hijack sessions.","url":"https://insights.sbomify.com/CVE-2023-37580/"}
