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-2023-4537 in the wild and no public exploit code.\n\nAffected product: Comarch ERP XL. 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-2023-4537/ (Markdown: https://insights.sbomify.com/CVE-2023-4537/index.md)","id":"CVE-2023-4537","markdown":"https://insights.sbomify.com/CVE-2023-4537/index.md","name":"CVE-2023-4537","record":{"aliases":["GHSA-58qw-vfcj-x2hg"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"ERP client software","requires_auth":"none","summary":"Attackers can force unencrypted communication in Comarch ERP XL clients, enabling interception and modification of sensitive data.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERT-PL","cpe":[{"product":"erp_xl","vendor":"comarch"}],"cvss":{"score":7.4,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-755","name":"Improper Handling of Exceptional Conditions"}],"description":"Comarch ERP XL client is vulnerable to MS SQL protocol downgrade request from a server side, what could lead to an unencrypted communication vulnerable to data interception and modification.\n\nThis issue affects ERP XL: from 2020.2.2 through 2023.2.","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":"Protocol Downgrade in Comarch ERP XL","id":"CVE-2023-4537","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"weak_cryptography","year":"2023"},"n_packages":0,"n_references":2,"next":{"headline":"Shared Key in Comarch ERP XL","id":"CVE-2023-4538"},"packages":[],"prev":{"headline":"My Account Page Editor \u003c 1.3.2 - Subscriber+ Arbitrary File Upload","id":"CVE-2023-4536"},"products":["ERP XL"],"published":"2024-02-15","related":[{"cvss_score":7.5,"headline":"Hardcoded password in Comarch ERP XL","id":"CVE-2023-4539","kev_date_added":null,"published":"2024-02-15"},{"cvss_score":6.2,"headline":"Shared Key in Comarch ERP XL","id":"CVE-2023-4538","kev_date_added":null,"published":"2024-02-15"}],"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-10-10","vendors":["Comarch"]},"summary":"Attackers can force unencrypted communication in Comarch ERP XL clients, enabling interception and modification of sensitive data.","url":"https://insights.sbomify.com/CVE-2023-4537/"}
