Prior to 2.7.8, the mport_fetch_index(), mport_fetch_bootstrap_index(), and mport_fetch_bundle() paths in libmport/fetch.c accepted non-HTTPS repository and package mirror URLs without a url_is_https() enforcement check. When a cleartext URL was configured or returned by mirror data, a network-positioned attacker could tamper with package index or package download traffic and compromise package selection or integrity. This issue is fixed in version 2.7.8.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-319","CWE-345"],"vendors":[],"products":[],"references":[{"url":"https://github.com/MidnightBSD/mport/commit/9b4d0f9192b243ee32266afa36dce430b257b921","tags":[]},{"url":"https://github.com/MidnightBSD/mport/pull/121","tags":[]},{"url":"https://github.com/MidnightBSD/mport/releases/tag/2.7.8","tags":[]},{"url":"https://github.com/MidnightBSD/mport/security/advisories/GHSA-v5pv-7gxw-74r5","tags":[]}],"exploitRefs":[{"url":"https://github.com/MidnightBSD/mport/commit/9b4d0f9192b243ee32266afa36dce430b257b921","tags":[]},{"url":"https://github.com/MidnightBSD/mport/pull/121","tags":[]},{"url":"https://github.com/MidnightBSD/mport/releases/tag/2.7.8","tags":[]},{"url":"https://github.com/MidnightBSD/mport/security/advisories/GHSA-v5pv-7gxw-74r5","tags":[]}],"hasPoc":true,"ai":null}
