CVE-2019-3877 SUSE CVE security@suse.de SUSE Security Team SUSE CVE-2019-3877 Interim 1 7 2025-02-17T02:20:32Z current 2021-05-30T14:22:54Z 2025-02-17T02:20:32Z cve-database/bin/generate-cvrf-cve.pl 2020-12-27T01:00:00Z CVE-2019-3877 A vulnerability was found in mod_auth_mellon before v0.14.2. An open redirect in the logout URL allows requests with backslashes to pass through by assuming that it is a relative URL, while the browsers silently convert backslash characters into forward slashes treating them as an absolute URL. This mismatch allows an attacker to bypass the redirect URL validation logic in apr_uri_parse function.
