The vulnerability is related to the injection of HTTP headers via a CORS ExposeHeader tag. The newline character in the ExposeHeader tag in the CORS configuration file generates a header injection in the response when the CORS request is made. In addition, the prior bug fix for CVE-2020-10753 did not account for the use of \\r as a header separator, thus a new flaw has been created.",null,[],[],[],[14],{"_key":15},"CVE-2021-3524",[17,19,21],{"_key":18},"USN-4998-1",{"_key":20},"USN-5128-1",{"_key":22},"USN-7706-1",[],[25,26,27],{"_key":18},{"_key":20},{"_key":22},"2021-05-17T17:15:00Z","2026-04-22T12:56:03.763163Z",{"cisa_kev":31,"cisa_ransomware":31,"cisa_vendor":9,"epss_severity":9,"epss_score":9,"severity":9,"severity_score":9,"severity_version":9,"severity_source":9,"severity_vector":9,"severity_status":9},false,[33,39,44,48,52],{"url":34,"sources":35,"tags":37},"https://ubuntu.com/security/CVE-2021-3524",[36],"osv_ubuntu",[38],"REPORT",{"url":40,"sources":41,"tags":42},"https://ubuntu.com/security/notices/USN-4998-1",[36],[43],"Advisory",{"url":45,"sources":46,"tags":47},"https://ubuntu.com/security/notices/USN-5128-1",[36],[43],{"url":49,"sources":50,"tags":51},"https://www.cve.org/CVERecord?id=CVE-2021-3524",[36],[38],{"url":53,"sources":54,"tags":55},"https://ubuntu.com/security/notices/USN-7706-1",[36],[43],[],[],[59],{"source":36,"cvss_v2_0":9,"cvss_v3_0":9,"cvss_v3_1":60,"cvss_v4_0":9},{"baseScore":61,"baseSeverity":9,"vectorString":62,"impactScore":63,"exploitabilityScore":64},6.5,"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N",6,7.2,[66],{"ecosystem":67,"name":68,"vendor":69,"product":68,"cpe_part":9,"purl_type":70,"purl_namespace":69,"purl_name":68,"source":9,"versions":71},"Ubuntu","ceph","ubuntu","deb",[72,78,81],{"version":73,"is_range":74,"range_type":75,"version_start":9,"version_start_type":9,"version_end":76,"version_end_type":77,"fixed_in":9},"lt10_2_11_0ubuntu0_16_04_3+esm2",true,"ecosystem","10.2.11-0ubuntu0.16.04.3+esm2","excluding",{"version":79,"is_range":74,"range_type":75,"version_start":9,"version_start_type":9,"version_end":80,"version_end_type":77,"fixed_in":9},"lt12_2_13_0ubuntu0_18_04_10","12.2.13-0ubuntu0.18.04.10",{"version":82,"is_range":74,"range_type":75,"version_start":9,"version_start_type":9,"version_end":83,"version_end_type":77,"fixed_in":9},"lt15_2_12_0ubuntu0_20_04_1","15.2.12-0ubuntu0.20.04.1"]
