{"id":"DEBIAN-CVE-2024-47252","details":"Insufficient escaping of user-supplied data in mod_ssl in Apache HTTP Server 2.4.63 and earlier allows an untrusted SSL/TLS client to insert escape characters into log files in some configurations.  In a logging configuration where CustomLog is used with \"%{varname}x\" or \"%{varname}c\" to log variables provided by mod_ssl such as SSL_TLS_SNI, no escaping is performed by either mod_log_config or mod_ssl and unsanitized data provided by the client may appear in log files.","modified":"2026-09-15T09:02:58.337114179Z","published":"2025-07-10T17:15:46.400Z","upstream":["CVE-2024-47252"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2024-47252"}],"affected":[{"package":{"name":"apache2","ecosystem":"Debian:12","purl":"pkg:deb/debian/apache2?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.4.65-1~deb12u1"}]}],"versions":["2.4.57-2","2.4.57-3","2.4.58-1","2.4.59-1","2.4.59-1~deb10u1","2.4.59-1~deb11u1","2.4.59-1~deb12u1","2.4.59-2","2.4.60-1","2.4.61-1","2.4.61-1~deb11u1","2.4.61-1~deb12u1","2.4.62-1","2.4.62-1~deb11u1","2.4.62-1~deb11u2","2.4.62-1~deb12u1","2.4.62-1~deb12u2","2.4.62-2","2.4.62-3","2.4.62-4","2.4.62-5","2.4.62-6","2.4.63-1","2.4.64-1","2.4.65-1~deb11u1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2024-47252.json"}},{"package":{"name":"apache2","ecosystem":"Debian:13","purl":"pkg:deb/debian/apache2?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.4.64-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2024-47252.json"}},{"package":{"name":"apache2","ecosystem":"Debian:14","purl":"pkg:deb/debian/apache2?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.4.64-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2024-47252.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
