{"cve":"CVE-2023-29046","nvd":{"published":"2023-11-02T14:15:11.217","modified":"2026-06-17T05:49:14.660","status":"Modified","description":"Connections to external data sources, like e-mail autoconfiguration, were not terminated in case they hit a timeout, instead those connections were logged. Some connections use user-controlled endpoints, which could be malicious and attempt to keep the connection open for an extended period of time. As a result users were able to trigger large amount of egress network connections, possibly exhausting network pool resources and lock up legitimate requests. A new mechanism has been introduced to cancel external connections that might access user-controlled endpoints. No publicly available exploits are known.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L","score":4.3},"cwes":["CWE-400"],"references":["https://documentation.open-xchange.com/appsuite/security/advisories/csaf/2023/oxas-adv-2023-0004.json","https://software.open-xchange.com/products/appsuite/doc/Release_Notes_for_Patch_Release_6243_7.10.6_2023-08-01.pdf","https://documentation.open-xchange.com/appsuite/security/advisories/csaf/2023/oxas-adv-2023-0004.json","https://software.open-xchange.com/products/appsuite/doc/Release_Notes_for_Patch_Release_6243_7.10.6_2023-08-01.pdf"],"products":["open-xchange:open-xchange_appsuite"],"source":"nvd","synced_at":"2026-10-19T21:40:11.519948003+00:00"},"epss":{"cve":"CVE-2023-29046","score":0.00478,"percentile":0.41267,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
